Wheels / Tires for Track Time

Jmatchley86 · 04-24-2019, 08:11 PM

Seeing alot of people saying they run a 10.5 in the front with no issues. I just went wider to this size in the front with a +15 offset (10.5 +15) and now i'm rubbing like crazy with a 275/40/18.

Its not in a turn but when I go over any halfway decent sized bump. I think its hitting the tab that holds the bumper in the wheel well. I already rolled the fenders and am only lowered on swift springs. Any advise here?

I ordered a quick release so I can remove the tab and am about to order some 35 aspect ratio tires. But if someone has words of wisdom i'm all ears.

at +15 you're going to have issues. You want to be around +21 to +30 if you want run 10.5 with moderate camber

Well thats just super... lol. Hopefully removing the bumper tab will solve my issue or doing a combination of that and 35 aspect ratio vs 40. I really don't want to spend the money (now) on a set of coil overs or konis to control the dampen rate.

I'm running a 10 wide up front with +18 offset. Fitment is absolutely spot on with -2 camber. What is your camber setup up front?

You would need to get more camber in front, on stock height there is no issues, but lowered you will need -3, -2.5 if fender rolled. I am lowered and don't have any issues with -2.7 front camber and around an inch gap between tire and fender.

With SPL FUCA I am able to get -3.2 and I am lowered an inch. I have no issues running 18x10.5 +30 or +15 and 275 35 tires. I also run a 18x11 +18 with a 315 30 tire and no problems so far.
