I found going to the 14" wheel is the only way to go! My car came with the 13" cosmics (one cast wheels and avon tires). When I purchased the car in Feb. of 75, the car's front tires look new the backs were missing a lot of rubber in only 7K miles!!! The wheel lug bolt inserts started to crack, about 10 years ago, which I thought was not safe. The lug bolt spacing on the GT6 was only used on a few other cars like the Lotus Europa. So the wheel selection was/is? limited at that time. With a gift form my wife, I went to wire wheels, Dayton build the wheels to fit the offset (at that time custom cost no more the stock order). Their wheels with SS parts are in general much stronger than wheels form England. The handling improved even with the Dayton's increase in swing weight over the cosmics (new tire tech is great). If you need any details I could go dig in my files.

Hi guys,

Mark could have a point there regarding the raising of the rear, which I
wouldn't recommend unless it's unnaturally low because it would effect the
handling, but I have another slant on the problem. Believe it or not but the
component of my 3 litre Volvo which most often comes in contact with the
road surface is the bottom of the clutch slave cylinder. In fact it got
ripped off the bell housing 2 years ago and I had to remove the engine and
transmission in order to detach the bell housing, which is made of aluminum,
and have it welded properly. I've had my oil sump welded a few times and the
last time it happened, I had a fairly substantial skid plate attached to
prevent a recurrence. I'm currently working on developing similar protection
for my clutch slave cylinder.

However, in my case, the problems of grounding are probably more to do with
putting Michelin 185/70 13 tires on the car many years ago, because their
diameter is at least an inch less than the original Avons. Not only did it
lower the car but it also causes my speedometer to over-read. I've been
intending on switching to 14 inch rims with lower profile tires that match
the diameter of the originals and I'm hoping to do it next Spring. I just
can't make my mind up about the rims. Does anyone have a suggestion for rims
that would compliment the car. I want something elegant that's not flashy.
Anyway, tire size is another component of ride height. Something to think
about.

Regards,

First off, there's only 1 LM600 road car in existence. It was built
to satisfy the FIA that the LM600 race car was a bona-fide GT and not
a one-off race special. Factory testers reported, even undeveloped
(all the return edges on the car were razor sharp!), that it'd exceed
170MPH and talked of a "developing it properly if someone comes along
with \ufffd100,000". The car was, to my knowledge, last seen with Eurotech
(Cor Euser's outfit) in Holland. There are some pictures of it
somewhere on my website, with Dutch trade plates over its English
plates.

Secondly, the pre-Mantula coupe is often described as having a high-
nose (there being no front spoiler), but looking at Jeff's photos his
car does look unusually high. I'd expect this to be solved by
lowering the setting of the spring seat on the shocks. However, it's
worth considering WHY this has happened. It could be a case of too
long springs, but equally (or maybe more) likely it's due to the car
dragging its sump on a lower setting (My sump's been welded 3 times
now!). So (daft as it may sound), it may well be worth raising the
rear suspension (perhaps not to match, but 50% down on the front, 50%
up on the front sort of thing), unless you live in area with pool
table smooth roads :^)

Cheers,

Mark
