Let me ask you this first...what suspension are you running?

I'm running that on my summer set up. It's great. I'm sure even 245's would be sufficient, but at that point if you can fit 255's why not. It handles like it's on rails. The stock zhp has 255's in the rear, so you're really only helping the front by reducing understeer.

sorry secono330ci for the mini jack
I dont care, the more discussion the better.
I did it for the same reason originally. Now that my car is a lot lighter and a bit more powerful, I actually need this set up. Since it's winter now, I'm running 225 square dunlop winter sports (winter tires are very grippy) and it's NOTHING like my summer set up...and my Nitto Invos are SHOT.

We use 9" wheels, but I'd think 9.5" would not be that dramatically worse if you stick to 255s. But then, I'm running 2.5* of camber rear and 2* camber for street driving up front.
That's about the same camber I'm running as well, good point. I dont know how easy 265's will be tho. The problem isn't the rear tire clearance, but the front. It needs to clear the strut, but at the same time have enough room to turn and not rip the fender out. It really is a game of trial and error.

This calculator helps a lot
