thoughts about track rims and tyres

[_Nathan_]

Could always take a look at the speedlines that the Torquespeed car is running?

The problem is I can not find a wheel manufacturer that make such a size wheel lol

This is what we developed with Rays, IMO ultimate spec for race/track wheels in terms of offsets and set up (whole process took 9 months of work).



Front 18/8.5/35 (run with optional 10mm spacer depending on track and conditions)

Rear 18/9.5/22

Remember going to wider rim will add weight ( it does make a difference, I can tell how my car drives from Rays to pro Race 1.2's even with same tyres on)

Tyre deformation is in part due to wheel width for sure but camber is also a major difference, run max on Dunlops.

We even have a set in stock

I looked at the rays in the offsets I wanted but too much money as I needed at least 6 of them. 9.5 is the best wheel size I think, a set of Rays 9.5 all round with spacers on the rear and 250/640/18 all round would be perfect

Running the pro race 1.2 18 x 9 all round, I felt the rear needs spacers.

Ive not measured the track, but from eye it looks narrower than the front. Ill measure it to be sure, but im defo running spacers on the rear. with 265 35 18 all round.

One thing to consider when talking about offsets, widths etc, saying it wont touch the arch or the strut, the style of the rim has to be taken into consideration,

John, i think we all are looking for one rim for all 4 corners mainly for track work so we can use one tyre and swap them round

yep, only trouble with Rays is the off puting nature of the initial price (and also then getting all the Evo drivers trying to rob them on trackdays)

,

def any rim/tyre combo on same froint and rear rims will need rear spacers to look sensible due to the difference in original offsets

But pink yeah?

[Nords]

never mind after them, I deffo want them, just been busy!!!! Gotta pick up my new daily $hitter from near you next weekend, so will probably get them then mate :thumbs:

So thats what a young glendog looks like, :smokin:

Summary so far;

Ray TE37 18x10 - 8.6kgs
TD Pro Race 1.3 18x19 - 11.75kg

Ray TE37 19x9.5 - 9.5kgs
BMW CSL 19x9.5 - 11.5kgs

So the 18 inch TD rims would be a better fit than the CSL wheels on the front as you could get the offset right and probably miss the wheel arch but they are no weight saving over CSL rims.

TE37 19 and 18 inch rims would save between 2 and 2.5 kgs per corner respectively (not unsubstantial) but cost alot more money.

Easiest option at first is to try the CSL rear rims on the front i guess to see what difference the extra rubber gives first and this at least means i have the tyres and rims so no need to spend for the test outing.

Issue therefore i guess is how to get the CSL rims under the wheel arch which comes down to more neg camber.:supz:


ANYBODY GOT ONE SPARE REAR CSL RIM FOR SALE

I got 6 18x10 1.3s and including all the packaging (each one separately packaged) the whole shipment came in at 66kg? (will weigh a single wheel soon).

[Thorney]

Rays certainly aren't cheap I grant you, we make naff all on them so I cant afford to stock them in high numbers so leadtimes are long too. Good news is that they are strong, 2 full seasons on my car and other than surface damage from contact they are good as new and balance up nicely.

And they look the bollocks too, not quite up with the BBS E88 IMO but certainly close!

How much are these in 19" and 18" ?

Thank you please.

Hi,

These are quite good wheels, reasonably priced
and the 18 x 9.5 et 20 all round would enable
wheels/ tyres to be rotated for track use.

They are quite light as well, and very strong.

Colleague ran them on his E36 GTR Track car and
was well pleased with them for the money.

The Gorilla.
