Anyway... the specs that of my Gram Lights 57DR was 18x9.5+12 & 18x10.5+22 (the offset arrive in +22 by a mistake) with 20mm spacers on rear. The front sit perfect with the 255/40/18 tires that I have up front... of course you have to give some camber, but nothing crazy... I have the Oem camber arms, etc. never rub on the fender or liners... they work perfect with the correct alignment. On the rear works perfect to... I use the 20mm spacers on the rear to make them flush with the Z body. The offset of the rear wheels suppose to be +12 too like the front. The specs of my rear tires was 285/35/18. I hope that helps something If you have any questions about my Gram Lights setup let me know... Those wheels are soo great that if I keep my Z, im going to buy them again hahhaa!
