And, most people never drive their Ferarris fast enough to notice.

GT2 Viper - A starting place might be Oreca they've run them for years http://www.orecaracing.com/index_flash.asp
-
They did that school car for Silverstone a few years back and I've been seeing their name come up all over the place as a development engineering outfit. But this isn't Supra technical is it?
-
Alex: looking for a big wing that works? you may find one of the GT2 Viper's wings if you ask about.
-
Chris: is that a supersports or what? I'm sure I've seen it Race Car Enginering, but can't find the copy. And is it one of Peter Sneller's designs?
-
Chris - is that a Panoz in your avatar, or just the world's biggest Mallock?
-
Want to make it quicker at a track day? - dead easy. Get rid of weight.
-
Scary undertray stuff eh?
-
Extremely expensive (you can't imagine) and not suitable for the road. I can't imagine why anybody uses more than UK spec with good pads on the road. Serious track day use is a different matter. Any decent caliper is going to be bigger than those nasty J-spec sliding things. Don't rule out UK calipers if you haven't measured the fit.
-
On a road car, wings are 90% cosmetic, 10% downforce at most. The old Sierra RS500 was reputed to produce 20kg or so at 100+mph and that's not a lot.
-
My CV joint grease claims a max working temp of 125°C whereas my copper grease claims 1350°C. That's a big difference. I imagine CW sees an issue other than melting point.
-
Never had a problem. I could look at the melting points.
-
Use a little copper brake grease if you have a sliding caliper that is sticking (ie J-spec), but it's quite likely that the only long-term solution is to strip and rebuild the calipers. We are talking about your Supra's brakes here!
-
Have a look at the shock-absorbers and see if there is any brand on them and also what colour they are. You may have the same TRD ones I have. This sounds like my car except for the tyre wear and wheel width. There are a lot of threads on which tyres are best but as you've tried Goodyear... don't know about Kumho except to say they are a budget brand. If you want to raise the car and soften it, you could do a lot worse than fit standard springs and dampers.
-
How low? Measure it under the front cross-member then I'll know if your ride-height is close to mine. What spring/damper set-up is on the car and what size/make of tyres? I run fairly low and get well over 10,000 miles out of my tyres. I agree the bumps are (lit) a pain in the arse.
-
Just measured mine, it's set at 2deg camber all round, front ride height is a 100mm measure under the front cross-member. The rear tyres are Bridgestone S01 275/35x17 and show almost 5mm after 9000 miles. Rear pressures are 34psi. Fronts are Bridgestone S03 245/40x17 and are showing 6mm after 8000 miles. Front pressures are 35psi. That's not bad tyre life with that set-up I'm sure you'll agree.
-
because... To "fill out the arches" implies larger rolling diameter. And you can recalibrate the speedo electronically.
-
This will raise the car not lower it. Mine runs quite low on quite hard springs, with TRD dampers and ARBs. Speed bumps are a nightmare, but on smooth roads it's good. Don't do it for cosmetic reasons alone.
-
Ah. I don't know what rolling circumference a stock tyre is. My speedo read bout 4% faster than the GPS but I expect that's normal.
-
Correct in what respect?
-
Alex, do you mean are the 17" tyres on 17" rims?
-
That was the best price. I was quoted £500 + fitting! With kerbing skills like that I'd buy steel rims and a big hammer:)
-
Steve, I can get the 275/35 x 17 but they're £440 a pair and I see a lot of people on this site buying much cheaper tyres. I can't complain too much I reckon they're good for 12/13000 miles.
-
The narrowest tyre I would put on these rims is the 275, but I have thought of going to a 40 series if availability is better. Yes the rims are at 10".
-
I've got 275/35 Rear and 245/40 fronts but on 17" rims. Getting tyres seems a complete nightmare to such an extent that I'm thinking of replacing the rims with 18s. When I bought the rears, it was Bridgestone S01 only, they were special order and Bridgestone only had 4 tyres in the country. Can anyone suggest any solution other than new rims? The tyres have done 9000 miles now and are looking a bit worn, and the rims need re-finishing anyway.
