Racing Tires
The stock Michelin tires grip good. However, does anyone know if the cup tires or better are available for the stock z51 rims?

I doubt if you will find a better tire, for the track, that fit the stock Z51 rims than the Michelin Super Sport Summer tires that come with the car. Just have to remember they are Summer tires and don't like cold temps. There are several on-line tire reviews that give this tire very good marks.
Some folks have swapped them out for the Michelin All Season 3 tires but they have no plans to track their cars and wanted a tire with a better wear factor. The A/S 3 tires are NOT run flats so keep that in mind. Hope this helps. |

I've been looking around quite a bit - maybe the Proxes R888. 285/35ZR20 in rear, 245/35ZR19 in front. They're R-Comps and I would be fairly sure they would outperform the PSS. Doesn't look like the wider tires will fit on stock rims per Toyo's specs. No testing or concrete data on my part, just going off R-Comps normally outperforming anything else (despite how good the stock tires are). Not run-flats, of course.

At what temperatures do the stock tires perform the best? I was driving the other day with temps in the mid-to-high 60's, and they still break loose a bit under WOT at around 5k RPM. Is that normal?

The real question is what the tire temp was. When autocrossing I normally want as much heat as possible in my tires (note: this is for the M Roadster I run while I break in the C7) and don't spray them down to cool until they're close to 120°F+. Some tires are best at even higher temps. Since the C7 just displays "warm", I would take a temp gun to them and see how it acts at different temps. Even at ideal temp, this car has enough torque to break any tire loose if you really push it!

I'd call michelin for exact range but I'd guess one you get over 120° they start to get real sticky but keep under 200 I would think.. I'll Google

Keep in mind, however, that even the grippiest tires will break loose with 465 ft/lbs of torque. The tire can't overcome physics

Well, I suppose you could fill the back of the car with bags of concrete. F=µmg and all that...too bad it's also a=F/m. Darn physics keeps trying to slow us down!
