I ran a CCW Classic Street Rim with 9" inch rim in front with a 25 offset and a 10.5" inch rim in back with a 30 offset. Tires were 265/35/18 and 295/35/18. No rubbing with -1.5 camber. This is probably one of the best track setups you can get under the Z without worrying. I ran Toyo T1S and also Pirelli PZero Corsa (R-Compound). PZero are pretty expensive and I'm not sure they even make a 295/35/18 anymore. But the Toyo's should come in those sizes.

 

Here's what can happen to you if you stretch the tire on the rim.. This is from the VRT guys. This is from a post on this board.

"UPDATE ON WHAT HAPPENED OVER THE WEEKEND

Saturday night was its first real test drive. Scott at VRT put 350 miles on it that night! The car did awesome on long trips and had no heat issues or oil leaks. Then Scott took it to some high speeds and noticed that the back end of the car felt a little wierd. Back to VRT he went to check the suspension.

The suspension checked out fine and and then he figured it out. It was the rear tires. Earlier that day they had hand measured the rear tire width. Although the Nitto NT01s were 315s, they actually measured out to be 323s. On the 9.5" rim, the 323s crossed just over the line of stretching the tire on the rim. What was happening was, at high speeds the tire was growing taller, like drag slicks, because they were stretched so much trying to fit the 9.5" rim.

The tires did not rub at all, it was just the stretching problem. So, what we are doing is switching back to the 315/30/18 Michelin Pilot Sport Cups that I was originally going to put on the car. The good news with that is they come in a 285/30/18 which will replace the 275/35/18s I had on the front with the Nitto NT01s. So I lose a tiny bit of width in the rear, but gaining more in the front."
