I used z force rears and the msa rear on the front and it worked out I'm using 9.5/255/40/17 in the front and a 11/295/35/18 rear,,the wheels are forge line custom,I begged, and begged them to build me a set of one offs to fill the correct offsets and still house my huge brake rotors,and 6 piston calipers! On the AZC full billet road race suspension.and an LS engine of course! and with the 17-18 combo the car roof is still just 46 inches off the floor
