100 Members !!

100 Members !!

2003-05-04 by Don Lattimer

Amazing! We've hit the 100 mark.  Hopefully we can hold that number 
and increase it over the summer as we find new members.  

A warm welcome to our 100th member Pat from Montreal, Canada !  I 
believe Pat owns a Marcos 3 Litre but I'll let him explain it all.

As for me, I took the Marcos to the Pacific Coast Dream Machines meet 
in Half Moon Bay, CA last weekend for a beautiful day filled with 
cars, planes, steam engines, truck pulls, bikes, and every other 
powered contraption that exists.  Only problem was the 4.5 hour ride 
home in the rain.  Heavy rain!  Yes, it leaks......

Mike and Mark had their Marcos at the Volvo meet in Davis, CA on Sat. 
and then on to Thunderhill Raceway in northern California for a track 
day (also in the rain).  Both enjoyed the excursion.

Any adventures from the rest of you folks??  

Have a good week!

I had my car at the Volvo show in Davis on Sunday and the weather couldn't have been better. As I left the show and headed to Willows, the closest town to the Thunderhill race track, I could see the weather start to change. By the time it got dark it was really raining. The next morning, Monday, I met Mark Petrinovich at the race track. It was wet, windy, and fairly cold (for California). By the time I got through registration and technical inspection I was really soaked. Mark went back to Willows and bought some rain-ex anti fogging stuff which we both smeared liberally all over the interior glass of the Marcos cars. Even with the rain-ex and the windows open we were still having problems with fogging since our clothes were wet. Add the rain on the rear window and the mirrors and we couldn't see much out of the cars. Mark quickly picked up the racing line and seem to be going good for his first encounter with Thunderhill. It probably helps that Mark used to race motorcycles. I was having problems with my DOT approved racing tires. They are wonderful in the dry but in the rain they are sort of marginal. After lunch the rain stopped and the track dried out so I had a good "go" during that session. My drive home was (200 miles) was fairy dry as the weather front moved out of the area. There is a shot of Marks car racing at Thunderhill on the Volvo Web site http://www.scvcoa.org.

Hi Guys,

Reaching 100 is quite the accomplishment. How many of those are in North
America? 

At the local Ancaster British car day last month, someone came up to me and
said they'd seen another car just like mine in nearby Burlington recently. I
figured he must have meant mine because I'm down that way quite often.
However, someone else asked me this weekend if I'd been in St. Catherines,
another nearby town, recently and that's a definite NO. So it appears
there's another Porcshe tangerine Marcos in the area. I wonder if Ron McLeod
has come across it?

I definitely wat to get new rims and tires in the near future and I've been
looking around for rims which fit my bolt pattern, which, if someone could
confirm I'm measuring it right, has a bolt circle (diametrically opposed lug
bolts) of 3 3/4" x 4. It doesn't look like there are many options available
for 14" rims and even less for 15" rims. I'm leaning towards a 205/55VR15
tire, which is made by a number of manufacturers, but coming up with
suitable rims could be a problem. Has anyone come across suitable rims for a
reasonable price? What's involved in changing the pattern to one that's more
common?

Any insight would be much appreciated.

Regards,

Paul Dransfield

Paul,
After squeeling and sliding around the Thunderhill track on my 195/70/13s 
with the nice folks of the Volvo Club of America,I too am motivated to 
upgrade my wheel and tire setup and I did bit of poking around a bit and was 
told that Panastort rims might be of use  to look into ,they are not cheap 
(about $250 each or so) but less costly than a new set of hubs and less 
expencive rims.I was told that they can drill the wheels at the factory to 
fit any bolt pattern.
Mike Denman hase a set of Panasports(14 inchers) so might want to check with 
him to get his oppinion.
A while back Don Lattimer was looking in to this very same subject.
Don?Any progress?

No, I haven't seen this car. Of course, I haven't been out much, as I am getting the new wheel bearings, and rebuilding the master brake cylinder, which I found to be leaking slightly when I go the car out of storage. (Was it cold enough last winter to freeze brake fluid?)

Re: [MarcosManiacs] 100 Members !!

Hi group,
Actually, I have 13 inch Panasport wheels, 7 inches wide (as I recall... I can check if someone really needs to know) with 4 1/4 backspacing. 4 1/4 back spacing is the maximum that will clear everything with 13 inch wheels.The first thing that will hit ( with 13 inch wheels) is the upper "A" arm on the front suspension. If I were to order the same wheels again I think I would go with a 4 inch back spacing to give a little more clearance. Panasport can do any 4 bolt wheel pattern from what I understand. 14 inch wheels weigh more and give you more unsprung weight which is a bad thing. My conversion from wire wheels to Panasports resulted in a savings of almost 60 pounds which made a huge difference in the handling. It also has a pretty big effect on the power to weight ratio since the car only weighs 1780 pounds. The 3 3/4 bolt pattern is correct for the Triumph hubs and the Cortina Rear end was stock at 4 1/4 inches. The Marcos factory would re-drill the Cortina rear axles to the 3 3/4 inch pattern. Unfortunately, the 3 3/4 inch pattern with Triumph studs is not the strongest assembly around. One way around this problem is to fit aluminum hubs in the front drilled to the 4 1/4 pattern and use the stock 4 1/4 Cortina rear axles. The aluminum hubs are expensive but available from Dave Bean Engineering in California. The aluminum hubs are also quite a bit lighter saving almost 3 lbs per front wheel (which is a good thing). I ended up with Toyo RA-1 DOT legal race tires on the recommendation from Roger Krause who sells Vintage race tires as well as modern race tires. I had originally set out to buy Hoosiers which are basically a DOT legal race slick figuring that I didn't ever drive in the rain so they shouldn't be a problem. So far I have had two track days in the rain and got caught on two long trips in the rain. The Toyo tires aren't great in the rain (as I found out at Thunderhill last weekend) but at least they aren't dangerous. In the dry they are great. They have a wear index of 40. (Pure race tires have an wear index of basically 0. My Yokohama AVS "performance tires" had a wear index of 160. So the lower the wear index the better the tire will grip... but the lower the wear index the quicker the tires will wear out.) However, tires get hard as they get old so wearing out the tires is not all bad. When I took the Yokohama AVS off the car they looked like new even though they were 3 years old (not a good thing). Because the Marcos is so light even the Toyo tires will probably last me a couple of years.

www.usacomp.com has "minilites" in just about any size you want.
The Mantulas have the alloy hubs on the front with 4 1/4" PCD to match the rear. The pre-1972 cars had the rears redrilled to 3 3/4" PCD to match the front. So the Mantulas have much more choice when it comes to wheels.
I've communicated with Chris in the UK and he currently runs 205/50-R15's all around but is going to switch to 195/55R15 in the front and 205/55R15 in the rear on his Mantula (with 4 1/4" PCD). He uses 15"x7" wheels with a 37mm offset.
The USAComp site is a big help in figuring this out. The "minilites" run about $240/wheel.

Thanks for the info Don. I was in contact today with an outfit in the US which sells Panasport wheels, which look like minilites. They're a Lotus parts supplier with a web site at www.rdent.com. They sell the 14" wheels with a 3 3/4" PCD for $175 but apparently the hub of the 15" wheel will not accommodate the 3 3/4" bolt pattern. I could get the alloy hubs for the front and redo the rears at 4 1/4" but I'd then need 5 rims and tires instead of 4. Unfortunately I'm not that keen on the minilites and wanted something a little different. I like the look of some of the American Racing wheels but they don't appear to have anything for a 3 3/4" PCD. Nothing's ever easy, is it, though I now know there's at least one option available.
The bottom line is I really like the look of 15" rims with 205/55VR15 tires but 14" rims with 215/60HR14s would be a lot easier to do. What do you think?
Regards,
Paul

Paul,
Looks to me like 205/60R14 tires come the closest to the original 185/70R13 circumference, although a liitle more(215/60R14) would improve ground clearance a little.
In my opinion, going to 14" isn't worth the price for 1/2" more tread width. I also like the looks of the 15" but you're right, "nothing is easy" or inexpensive!
Minilites don't excite me either, especially in the 14" and 15" sizes. They "mini" for a reason. They look great on 13".
The 195/70HR13 tires I have now ride nice (I don't race, yet!), are good in the rain, and fill the wheel well nicely. Guess I'll be satisfied for now but I'll keep looking for other options also. The UK guys have a lot of suggestions, just a matter of sorting them out. Although I like the looks of the 15", I have to keep in mind safety, handling, etc. when changing sizes of wheels and tires.

RE: [MarcosManiacs] 100 Members !!

Don,
I originally had Avon 175SR13s on my car which have a diameter of 23.94", according to the Roger Kraus Racing tire guide. I went to 185/70R13 Michelin ZXs when the Avons wore out and have had them on the car for 21 years now. Obviously I don't put many miles on my car on a yearly basis. The tires perform very well (at least they did), even though they squeal a lot these days, and I don't drive in the rain so the hardened rubber hasn't effected the handfling.
As Mike Denman noted last year, using old tires isn't the best idea and I suspect mine have deteriorated because they won't balance properly any more. A shaking has built up slowly over the years making it less enjoyable to drive, so I thought I should do something before I shake the car to pieces. There are two problems with the 185/70R13s from my perspective. They don't fill the wheel opening properly and they cause my speedometer to over-read. According to the specs, they should only be 2/10" smaller than the originals but they look much smaller than than that, either in actuallity (though I haven't actually measured them) or as an optical illusion.
The 205/60HR14 on paper is slightly smaller than the ZX, so that isn't an option. I reckon the larger 215/60HR14 would fill the wheel opening better and correct the speedo problem as well, and they're only slightly larger than the 195/70HR13 which you use. The 225/55VR14 has the right diameter but it's too wide.
My Cosmic rims are not in very good condition. I've tried to polish them up but they still look battered and dull. I need new rims in any event so I might as well have what I want if they're available anywhere at a reasonable price. That's why I was intrigued by your latest email about Pete Paulsen. I've sent a note off enquiring about the possibility of accommodating the 4 x 3 3/4" PCD. At 15", the 205/55VR15 would be just about right and the Daytona in chrome wouldn't look bad at all.
As a final note, a Canadian, Ted MacGregor, has a red 3 litre Ford. He used to live locally before he moved out west. I've since heard he moved back to Ottawa but he hasn't surfaced in years. Anyway, his car had very wide, low profile tires as I remember and he said they handled very well. I guess the proof is in the pudding as they say.
Regards,
Paul

Paul,
Looks to me like 205/60R14 tires come the closest to the original 185/70R13 circumference, although a liitle more(215/60R14) would improve ground clearance a little.
In my opinion, going to 14" isn't worth the price for 1/2" more tread width. I also like the looks of the 15" but you're right, "nothing is easy" or inexpensive!
Minilites don't excite me either, especially in the 14" and 15" sizes. They "mini" for a reason. They look great on 13".
The 195/70HR13 tires I have now ride nice (I don't race, yet!), are good in the rain, and fill the wheel well nicely. Guess I'll be satisfied for now but I'll keep looking for other options also. The UK guys have a lot of suggestions, just a matter of sorting them out. Although I like the looks of the 15", I have to keep in mind safety, handling, etc. when changing sizes of wheels and tires.

Thanks for the info Don. I was in contact today with an outfit in the US which sells Panasport wheels, which look like minilites. They're a Lotus parts supplier with a web site at www.rdent.com. They sell the 14" wheels with a 3 3/4" PCD for $175 but apparently the hub of the 15" wheel will not accommodate the 3 3/4" bolt pattern. I could get the alloy hubs for the front and redo the rears at 4 1/4" but I'd then need 5 rims and tires instead of 4. Unfortunately I'm not that keen on the minilites and wanted something a little different. I like the look of some of the American Racing wheels but they don't appear to have anything for a 3 3/4" PCD. Nothing's ever easy, is it, though I now know there's at least one option available.
The bottom line is I really like the look of 15" rims with 205/55VR15 tires but 14" rims with 215/60HR14s would be a lot easier to do. What do you think?
Regards,
Paul

www.usacomp.com has "minilites" in just about any size you want.
The Mantulas have the alloy hubs on the front with 4 1/4" PCD to match the rear. The pre-1972 cars had the rears redrilled to 3 3/4" PCD to match the front. So the Mantulas have much more choice when it comes to wheels.
I've communicated with Chris in the UK and he currently runs 205/50-R15's all around but is going to switch to 195/55R15 in the front and 205/55R15 in the rear on his Mantula (with 4 1/4" PCD). He uses 15"x7" wheels with a 37mm offset.
The USAComp site is a big help in figuring this out. The "minilites" run about $240/wheel.

Paul,
After squeeling and sliding around the Thunderhill track on my 195/70/13s with the nice folks of the Volvo Club of America,I too am motivated to upgrade my wheel and tire setup and I did bit of poking around a bit and was told that Panastort rims might be of use to look into ,they are not cheap (about $250 each or so) but less costly than a new set of hubs and less expencive rims.I was told that they can drill the wheels at the factory to fit any bolt pattern.
Mike Denman hase a set of Panasports(14 inchers) so might want to check with him to get his oppinion.
A while back Don Lattimer was looking in to this very same subject.
Don?Any progress?

Paul!

I am the 100th member of this fine group. And I have been waiting for years to chat with Marcos owners, about wheels, tires, gear ratio, etc.
I have Ted MacGregor's former Marcos 3L Ford V6, serial number 3L5365. It still has the 13x8 front and 13x10 rear MINILITES. The tires are the same Pirelli Cinturato CN36 P215R60-13(front) and P235R60-13 (rear). They are 23.15" O.D and 24.10" O.D respectively. I am due for new tires but cannot find replacement. I am considering to go to P235R50-14 (25.10" O.D)at the rear. I want to preserve the look of that car and will have to go with similar looking wheels. I would much prefer to leave it the way it is if I could find tires. Considering that I rarely use the car, I could probably make good with racing tires. I am also planning to install different rear end gear ratio. The existing 3.58 @ 1 is terrible on the expressway. 3.0 @ 1 would be better. I will likely end up replacing the whole unit as there isn't any choice with this Salisbury unit. I would have better luck with a Ford 8" unit as equipped with 2.8L V6 Capri or Mustang. I have plenty of projects but no time. I enjoy reading your letter and will get back to you with information about the wheels when I get back home. I live near Montreal, Quebec but work in Saint John, New-Brunswick. I have my Daimler SP250 here with me so it is not all that bad without the Marcos. Here are some pictures. Best Regards to all.

Hi Ted,

Welcome to the group. I've often wondered what happened to Ted MacGregor and
his red V6. He really loved his car. What made him give it up? I last saw
him in the late 70s when he, Mike Mitchell and I took part in a sports car
meet at the King City conservation area north of Toronto. That was the last
time 3 Marcos coupes were seen together in this part of the world. I have a
photo of the event somewhere. Mike Mitchells white V6 is now owned by Simon
Edlin of Markham. Last I heard, Simon was planning to race the car at
Mosport and other local tracks. 

Your car has really held up well over the years. It looks just as I
remember, with the flared rear wheel wells and fat tires. When you have
time, please give us more about information.

Thanks,

Paul Dransfield

Hey Mike,
I'm not having much luck sourcing 15" wheels with a 3 3/4" bolt circle. The Pete Paulsen wheels aren't available in that size. Maybe I should look at those aluminum hubs you mentioned. Do you have a part number and their cost? The Discount Tire Co. sells a number of 15" wheels which accommodate a 4 1/4" PCD for a reasonable price.

Paul

Hi group,
Actually, I have 13 inch Panasport wheels, 7 inches wide (as I recall... I can check if someone really needs to know) with 4 1/4 backspacing. 4 1/4 back spacing is the maximum that will clear everything with 13 inch wheels.The first thing that will hit ( with 13 inch wheels) is the upper "A" arm on the front suspension. If I were to order the same wheels again I think I would go with a 4 inch back spacing to give a little more clearance. Panasport can do any 4 bolt wheel pattern from what I understand. 14 inch wheels weigh more and give you more unsprung weight which is a bad thing. My conversion from wire wheels to Panasports resulted in a savings of almost 60 pounds which made a huge difference in the handling. It also has a pretty big effect on the power to weight ratio since the car only weighs 1780 pounds. The 3 3/4 bolt pattern is correct for the Triumph hubs and the Cortina Rear end was stock at 4 1/4 inches. The Marcos factory would re-drill the Cortina rear axles to the 3 3/4 inch pattern. Unfortunately, the 3 3/4 inch pattern with Triumph studs is not the strongest assembly around. One way around this problem is to fit aluminum hubs in the front drilled to the 4 1/4 pattern and use the stock 4 1/4 Cortina rear axles. The aluminum hubs are expensive but available from Dave Bean Engineering in California. The aluminum hubs are also quite a bit lighter saving almost 3 lbs per front wheel (which is a good thing). I ended up with Toyo RA-1 DOT legal race tires on the recommendation from Roger Krause who sells Vintage race tires as well as modern race tires. I had originally set out to buy Hoosiers which are basically a DOT legal race slick figuring that I didn't ever drive in the rain so they shouldn't be a problem. So far I have had two track days in the rain and got caught on two long trips in the rain. The Toyo tires aren't great in the rain (as I found out at Thunderhill last weekend) but at least they aren't dangerous. In the dry they are great. They have a wear index of 40. (Pure race tires have an wear index of basically 0. My Yokohama AVS "performance tires" had a wear index of 160. So the lower the wear index the better the tire will grip... but the lower the wear index the quicker the tires will wear out.) However, tires get hard as they get old so wearing out the tires is not all bad. When I took the Yokohama AVS off the car they looked like new even though they were 3 years old (not a good thing). Because the Marcos is so light even the Toyo tires will probably last me a couple of years.

Dave Bean can supply either the 4 X 3 3/4 or 4 X 4 1/4 or supply the hubs undrilled so you can drill your own. I currently have a set of the 4 X 4 1/4 on my Marcos and have another set for a Lotus 7 I own. The hubs are well made, save 3 pounds per wheel in unsprung weight but they are fairly expensive. The part # for the hubs differ depending on whether you have small spindles or large spindles but the 4 X 4 1/4 large spindle part number is 050C 7425. The small spindle part # is 036C 7425. There are other part numbers for other configurations.The person to talk to at Dave Bean is Tom (although most of the guys answering questions are pretty good). Tom is the senior guy and is also the manager so he knows what he is talking about. Tom knows about my Marcos and has seen it in person. Another employee at Dave Bean actually has a Marcos that has the 4 cylinder Ford engine.

Hi Mike,
I didn't even know there were different spindle sizes. I haven't a clue which ones I have. Do you know their diameter? How much is 'fairly expensive'. I'm going to have to take a close look at both the front and rear hubs on my car when I go home this weekend.

Hi Paul,
The easiest way to tell which spindle/axle you have is to measure the outboard bearing inside diameter. It will be either 5/8 (.625)(small) or 3/4 (.750)(large). Current pricing for the 4 X 4 1/4 inch hubs (without studs) is $217 each.

Do you have a part number and their cost? The Discount Tire Co. sells a number of 15" wheels which accommodate a 4 1/4" PCD for a reasonable price.
Regards,
Paul

Hi group,
Actually, I have 13 inch Panasport wheels, 7 inches wide (as I recall... I can check if someone really needs to know) with 4 1/4 backspacing. 4 1/4 back spacing is the maximum that will clear everything with 13 inch wheels.The first thing that will hit ( with 13 inch wheels) is the upper "A" arm on the front suspension. If I were to order the same wheels again I think I would go with a 4 inch back spacing to give a little more clearance. Panasport can do any 4 bolt wheel pattern from what I understand. 14 inch wheels weigh more and give you more unsprung weight which is a bad thing. My conversion from wire wheels to Panasports resulted in ;a savings of almost 60 pounds which made a huge difference in the handling. It also has a pretty big effect on the power to weight ratio since the car only weighs 1780 pounds. The 3 3/4 bolt pattern is correct for the Triumph hubs and the Cortina Rear end was stock at 4 1/4 inches. The Marcos factory would re-drill the Cortina rear axles to the 3 3/4 inch pattern. Unfortunately, the 3 3/4 inch pattern with Triumph studs is not the strongest assembly around. One way around this problem is to fit aluminum hubs in the front drilled to the 4 1/4 pattern and use the stock 4 1/4 Cortina rear axles. The aluminum hubs are expensive but available from Dave Bean Engineering in California. The aluminum hubs are also quite a bit lighter saving almost 3 lbs per front wheel (which is a good thing). I ended up with Toyo RA-1 DOT legal race tires on the recommendation from Roger Krause who sells Vintage race tires as well as modern race tires. I had originally set out to buy Hoosiers which are basically a DOT legal race slick figuring that I didn't ever drive in the rain so they shouldn't be a problem. So far I have had two track days in the rain and got caught on two long trips in the rain. The Toyo tires aren't great in the rain (as I found out at Thunderhill last weekend) but at least they aren't dangerous. In the dry they are great. They have a wear index of 40. (Pure race tires have an wear index of basically 0. My Yokohama AVS "performance tires" had a wear index of 160. So the lower the wear index the better the tire will grip... but the lower the wear index the quicker the tires will wear out.) However, tires get hard as they get old so wearing out the tires is not all bad. When I took the Yokohama AVS off the car they looked like new even though they were 3 years old (not a good thing). Because the Marcos is so light even the Toyo tires will probably last me a couple of years.

Paul,
After squeeling and sliding around the Thunderhill track on my 195/70/13s with the nice folks of the Volvo Club of America,I too am motivated to upgrade my wheel and tire setup and I did bit of poking around a bit and was told that Panastort rims might be of use to look into ,they are not cheap (about $250 each or so) but less costly than a new set of hubs and less expencive rims.I was told that they can drill the wheels at the factory to fit any bolt pattern.
Mike Denman hase a set of Panasports(14 inchers) so might want to check with him to get his oppinion.
A while back Don Lattimer was looking in to this very same subject.
Don?Any progress?
Regards,
Mark Petrinovich
