Incorrect. My 2005 997.1S PCCB are 350mm all around with 6 pots up front and 4 pots in rear. IIRC there were different versions of 997.1 PCCB (380mm vs 350mm, front different from rear, 6 pot vs 4 pot, etc), but I'm not 100% sure about that. I can attest, however, that "Front 997.1 PCCB = 380mm" is an over-generalization and, depending on the car, incorrect.

I can't comment on whether 380mm applies to 997.2 steel or PCCB, but it certainly doesn't apply to every Front 997.1 PCCB

Thanks...and that's great news! Because those wheels were, in fact, the exact OZ's I was alluding to. I wonder if the PCCB is a different size caliper than Big Reds, however? IE, might they clear your Big Reds, but not my PCCB (once I upgrade to 380mm)? I wouldn't be surprised if the PCCB caliper is a few mm larger than Big Beds and therefore wouldn't necessarily work with the 18" Alleg HLTs. Based on your pic, there certainly doesn't appear to be much room for error!

I'd love to hear someone confirm that 6 pot Big Reds and 6 pot PCCB are the exact same size, tho!

I use Fikse 18" on my GT3 with PCCB. I also have 18" BBS and 19" OZ if interested in purchase.

Bumping an old thread... any chance any of you all know if Work Brombachers in 18" will clear the 380mms?

Should anyone be looking for centre lock 18 inch wheels for 997.2 GT3, I have two sets of OZ wheels for sale.
