I'm getting Volk GTU's for my turbo II. 18X9 in the rear and 18X8 in the front, I want to know what offsets i should get. Thanks for your help.

please help! i need to know what offsets to get, i was thinking 38 front and 40 rear? maybe

 

I was trying to figure out wheel fitments for an FC a while back and after a bunch of searching and posting I came to these numbers (granted, they are for 17" diameter wheels):

Front – 17x8” +35 5x114.3; 235/40-17
Rear – 17x9.5” +38 5x114.3; 255/40-17

8" +38 in front should probably not be a big deal although you might want to try and find something in +35. 9" +40 in the back will definitely be fine. I did some more looking into stuff for you and found all of the available offsets and such that the GT-U is available in. In both 18x8" and 18x9" they make +36, +37, and +38 offsets. Each of these is built with a different disc which allows for more or less caliper clearance. In front I'd definitely go +36 because it's closest to that +35 number I was given. In back I would go +37 because you don't need as much caliper clearance and this will pull the wheel in a tiny bit which hopefully will prevent it from rubbing.

As for tire sizes I don't know if those are the absolute limit since those are figures quoted to me by someone else, but to get similar diameters you would need 225/35-18 F and 255/35-18 R.

So um, hope that helps.

 

We've tried a 17"x8" +35mm Work Rezaz Roars on a Kouki FC3S with 235/40/17 (Bridgestone S02's, I think), and we needed a 5mm spacer to fit up front.
