I'm selling a set and a guy with a 997 wondered. We are talking about the 380mm rotors.

Thanks for the help!

 

Why would someone want to go to 18's and I think you would have a problem with the calipers also.

 

18s perform better and give you a much greater range of tires for track use. Cup cars run 18s. Only a handful of 18s will clear the 380 PCCBs. I run them with 18x9 CCW and they clear. You need a 9" wide wheel like a CCW C10/14, BBS E88, Finspeed, and a couple of others...

 

So you don't think my 18x8.5 45mm offset would work?

Rears are 18x11 63mm offset.

 

I highly doubt it but only one way to find out.
