Dave,
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.
Jose,
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.
