GT3DE

I am converting my 2010 GT3 (street car, not a cup car) from the stupid street car center locks to the Cup car center locks. Now I will need new wheels. I race this car and plan on using the PCA GTC4 spec Pirelli tire.
What sizes are the 997 Cup car wheels?
Are they the same as the 996 Cup car wheels?
Anyone have a few (2 or 3) used sets they would like to sell me?
Thanks

Clarke, were I you, I'd buy new if at all possible.

Wheels are maintenance items. At the level Cups are driven (and at your level), I'd be leery of used.

GT3DE

so what wheels does everyone use? BBS?

Yes, it is the first choice.

Others make them like Forgeline, but BBS is the go to because they were what came on the cars. I can tell you all about center and half sizes and part numbers for the 6cup, but not for the 7cup.

Thanks

PCA club racing requires three-piece wheels for GTC3 (and GTCx?). That pretty much means BBS wheels.

check out finspeed wheels

i have had them on 2 race cars and i love them, fit and finish is amazing and they do custom.

I am a BBS guy myself. Have 3 set for my GT3 and 5 sets for the RS. Looking to sell the GT3 centerlocks and replace with Cup car centerlocks.
Anyone have a few used sets for sale?

If you run cup wheels and tires they will rub, the cups have limiters in the steering rack to prevent that.

The 12 and 13 cars run one piece from the factory however it's a wide body car u think...

Cup car racks are cheap and that will go along with your electric power steering. Unless Factory Cup dont think anything you do will get you in GTCx. The way I read it you would have to run GT Class regardless.

There should be plenty of 2006-2009 Narrow Body 997.1 Cup BBS wheels kicking around with center lock assembly.

A lot of cars were converted to grand-am 5 lug therefore somebody has a nice stash of BBS cup centerlock wheels...
