I was going to get the Z06 Motorsports on my car, but I found out they weigh too much. And for those questioning weight vs. acceleration, check out this movie:

I'm guessing if the chrome wheel weighs more than the standard wheel it isn't by much as it's just a coating, right? Hopefully! If the difference is only a pound or two I won't care.
edit: eek!!!
Combo 1: Stock 17" Z06 Wheel with stock 265/40-17 = 43 lbs
Combo 2: Chrome Z07 Wheel with Nitto 555R Drag Radials 305/35-18 = 59.5 lbs
=/ Now I'm torn...oh well, I'll decide!
