Looks like they are only in 5.114, but heres the linky! http://stores.shop.ebay.com/Cosworth-Inc__W0QQ_armrsZ1 PFF7s for 600 a set! I would grab these up if they had them in my bolt pattern!
HOLY CRAP! GC05Fs for 250 a piece?! That's insane. This is your chance to get a super screaming deal on Prodrive wheels.
BTW, you are not going to get into a forged wheel for that price ever. 250 a piece is practically robbery. The GC05Fs list for over 600 a piece.
+1 to this. The GC-05 is my favorite wheel style, and made by Rays. If this was 5x100 I would have bought a set. Such a killer deal. I am still tempted to buy them and then convert to 5x114.3.
