OK goes so im in the market for some custom wheels. i cant get this offset stuff correct. Im stumped. Ok so we all know Greg from facebook with the red (96-98) gt on XXR 531. I based all of my calculations on his setup. I am looking into getting 18x9 and 18x11 Work Wheels standard fitment of the sn95: 18x9 +20 18x10.5 +28 My calculation of gregs set up: 18x8.5 +20mm; lip=3.46 b.s.=5.037 18x11 +20mm; lip 4.71 b.s.=6.287 since he has a 5/16" spacer, i tried to do a conversion and came up with 18x11 +28mm lip= 4.40 b.s.=6.6 what i came up with to have a "flush" look is 18x9 +25mm lip=3.5157 b.s.=5.48 18x11 +28mm (with no spacer) lip=4.4 b.s. 6.6 i was messing around with the calculations a little more and came up with this. based on the 18x11 +20mm with a 5/16" spacer i can get a 18x11 -1mm with a lips of about 5.02 and b.s. of 5.97. I was just wondering what people think? am i doing this right? do you have any pictures of what a 18x9 +20mm or +24mm look in the front? and a 18x11 +28mm in the rear? Thanks guys.
