I'm using a custom setup from CCWheel. John suggested we (he made a run of about six sets for the Z06) set the front track out about 1/4 inch and the rear out about 1/8 inch. Tires are 245 40x17 front and 275 35X18 rear Hoosier autocrossers. I think the setup should be good, and it defintily looks good. I'm going to Roswell, NM for a test and tune 17,18 Feb then to Divisional in Phoenix on 24, 25 Feb. I'll know much more after that. Let me know if you have any specific questions.
I will be running BFG gforce R1A 295/35-18 with 275/40-17 in the front. Being that my car will arive in 2 to 3 weeks, I have not had a chance to try them. I was able to run two Solo II events with my 94 Vette with Grand Sport wheels. I wanted to compare the Hoosier road race compond to the BFG. So, I put the tires on the front wheels. The Hoosier seem to work much better. The reason I am running the BFG's is that I saw them on tirerack's web site for the rear for $120 and I bought four. The performance I feel will improve for the BFG when it heats up down hear in New Orleans and the added width will also help. Regardless, it seem BFG is pulling out and know one else is making an ideal tire for the Z06 rears. A 295/30-18 would be great.

No. I've weighed the CCWheels without tires, but not the originals. The five pound saving is wheel and tire combo together. It's not five pounds exactly, and I don't remember the the exact numbers, but if you need them, let me know, or we'll talk in Phoenix. My scale is very acurate.
You've made a wise purchase. That's an execellent price for Z06 tires. None of us know, at this point, what tire will work best with the Z06, but we'll learn fast. Whether it's Hoosier, Kumho, or BFG (less likely given they are not making autocrossers anymore) we all need tires to practice on. I plan to move to 305/zr30 18 autocrossers, which Hoosier says will be availabie on 21 Feb, but they are $255 each. Needles to say, I won't be using them for much of my practice runs.
