Anyone use Toyo proxy R888?
Thinking about putting a set of 275/40/17 & 305/35/18 R888 on my z06 stock wheels. Any one run this set up? I have used tripe eights before on my isf but didn't now if there's a better choice for a weekend track Z.

I don't know what size you're trying to fit, but both the 305/35-18 and 315/30-18 R888 are spec'd to fit on a 10.5" wheel
If you don't want the same diameter tires up front as out back, you'll have to choose your front tires carefully with the 25.5"-tall 315/30 (the 24.7" 245 or 25.1" 255/40-17, for example, should work fine with the TC/AH system)

Typically you can bump up 1 or 2 sizes on the stock rims. The R888s are a good option for the street and track. The Nitto NTo1s have a bit more grip on track as far as I'm concerned, but have a shallower tread depth.

The 275/40-17|305/35-18 combo will fit fine on factory wheels

It would run a hair high since those are a bit shorter than factory (as opposed to it running a couple MPH low as your car sits right now on the slightly taller tires), but you probably wouldn't want to run those with your 275/40 fronts; 255/40 would be a more appropriate height for that rear tire
