Aggressive offset guys, little help please
 
So Im looking into a new set of wheels for my FD. Performance is #1 priority, but in reality the car will see more street/show time that actual track driving, and I do like the look of a flush and aggressive wheel setup. For the wheels Im looking at, I basically have 2 options. The 1st, which is still aggressive is 18x8.5 +32 fronts, 18.9.5 +35 rears. Probably run 245/265 stagger tire. I know this can be accomplised with just fender rolling. The second IMO is pretty extreme, and would be 18x9.5 +35F, 18x10.5 +12R. I would like to run a 265/285 stagger with these. I realize some pretty moderate rear fender pulling would need done to the rears with this low of offset, but my question is could this actually work on a track? Im running Zeal Function Xs coilovers (10/8 springrates) at a rideheight of about 25" ground to fender. Again, dont want to have to run more than 1* static camber, and want this to work under suspension compression on a track or hard driving. I realize the 1st are still a bit aggressive but would be safer, but the 2nd fitment would allow for a more concave wheel and I think look better. Just looking for some input from guys who may have run this type of setup before. In previous setups Ive had 18x9.5 +45 SSR GT2s all around in 265/35r18, and 18x10 +50 CCWs with 285/30r18 all around. So even with the 2nd scenario with the 18x9.5 +35s up front, thats only 10mm further outboard than Ive ran with my SSRs, which Im thinking shoud be ok?? Thanks!

The question is are you willing to make it work. With an aggressive roll and pull you can make the sizes work, I am not sure if 285s will fit. That depends on what brand of tire you want too.

If you just want something that fits, go with something more conservative.

I would also check of the overall diameter of the tires is the same for performance driving.

Understandable, anything can be made to work with enough effort. But being that Ive never really ran a low offset setup before, Im wondering if anyone can tell me what will be needed to make it work? Looking at goreify's XD9 setup, he was running 18x10+38 fronts (pushing them out to an effective +33 with a 5mm spacer), and 18x10+18 rears, with 255/35s on all 4. Now judging by that, my fronts aren't going to quite as aggressive, but my rears are, especially with the larger tire. The more I think about it the more I just may go with the more conservative setup, as I really dont want to molest the fenders on my car. I just know those concave rears would look amazing.

Ok so the only amicable solution I could come up with for the fitments offered in the wheel you want are:

9.5 +35 front and rear. Run 265/35 front and rear.

Yes the front will be pretty darn flush with whatever you can find to roll under there. You might need to run a little camber.

I''m sure you noticed that the more concave face probably won't be an option at all.

Even if you were to get the Shine Burnout fenders this would be your limitations

The fitments, imho would be

18x9 +25 with 255/35/18
18x10 +25 with 285/30/18

ergo

18x9.5 +31
18x10.5 +31

While it is minor a 265/35 will be taller than the 285/30. I'd do the 255/35. In all reality if you can run a

10+38 front with Burnout fender and 285/30
10+38 rear with Stock Rolled Fenders and 285/30

You'll have a pretty sweet setup. i'm sure you can get this to a +35 with some more trimming.

Hopefully you can use this as a reference and interpolate offsets and tire widths from these baselines.
