Default Re: Non-stock wheels/brakes? What about spare tire?

Anybody else w suggestions?
I got a '09+ CTS spare wheel/tire kit. The bolt pattern is correct, but the hub size on the wheel is slightly too small. It needs to be machined, but wouldn't be a big problem. I never machined it because I sold the car. But it appeared to have plenty of brake clearance, especially to the side, as the Baer 6-pot was pretty wide on my car. The CTS's have 21mm wheel nuts vs 19mm on the C4, so the C4 lug nut might not engage the entire shoulder on the wheel, but I believe it would hold it on there properly, especially just for spare-tire type driving.

They are 18" wheels, and I have heard of people with 2nd gen CTS-V's using them for skinnies. Those cars have bigger brakes than the C6Z does. They may use spacers for that, though.

The tire is also the right size for a stock C4Z, though it might be shorter in height than your C6Z wheel setup. If I recall, it is a 135/70-18 on an 18x4" aluminum 5-spoke wheel.

Edit: I only read the first post initially, it looks like Dave/WVZR-1 covered this.

FWIW, I picked my kit up on craigslist brand new (tire still unmounted) for like $150. That has the jack and whatnot too, not that it would work on the 'vette. At $350+ it is less compelling.
