Z06 wheels fit?

[Bolling]

Will C6 Z06 wheels fit our ZR1's and how bad would the speedo be off?

You will need a spacer or wheel adapter for the rears. not a big deal.

Yes and speedo reads about 3-4 mph slower at 70 (used GPS to verify) with a stock 3.45 gear. Some dependency on tire height also. Fitment on the fronts is really more dependent on the rotor offset you are using. I originally had Brembos w aluminum hat which caused the tire to protrude past the front fender lip by maybe 1/2". Using the stock Z06 rotor however brings the tire flush w the fender. Besides using 18mm spacer (wheel and hub centric) you'll want to install
longer wheel studs. I got the GM studs for higher tensile strength.

Tire dimensions are the only thing that determines speedo/odo accuracy, wheel dimensions have "no effect". I might have guessed that a moderator might have moved the thread to a more appropriate topic area for the OP.

Thanks for all the info

I used a wheel adapter so I didnt have to change out the studs
