I'm considering going 4 corners 18x10.5 (front +22 -2.5* camber, rear +18 -1.4* camber) and running 275/35 R888s..(~10.9" wide)

anyone else tracking this size? how does it feel? neutral?

 

I believe Steve Mitchell (of M-Workz) is running 18x10.5 all around with 295/30 and 315/30 Hoosier R6.

 

Why so little negative camber in the rear and so much up front?

I think -2 and - 1.7 would be better.

rear i want as much contact patch as possible with my turbos kicking in i'd like to have more grip in the rear ..

front cambered a bit more for better turn in response.. but i'm not quite sure how much better (or worse) it will be with fronts being 10.5 wide...

 

I have 565 whp and have the 295 R888's. I have -1.7 negsative camber on the rear and I have full traction on the track when they are up to temp. I don't know if that helps you any.

I am tracking 275s at all 4 corners, and yes it is quite neutral. This is on 17x9.5" wheels though. I see no need to run a 10.5" wheel without the tire to demand it.

 

I'm running 18/10.5 all around with 315 A6's. I think the fronts are +15 with a 1/4 spacer and the rears are +35 (I didn't want to roll the rear lip) Obviously, I had to do some fender modification.

While I haven't been on 4 brand new tires since I bought the wheels, I would say that the increased front track width has helped turn-in and understeer quite a bit. If anything, I have rear traction issues, but I'm planning on making some offset bushing to help that problem. F camber 2.75 R camber 2

 

I'm running 18 x 10 RPF1s with 38 mm offsets all around and 285/30-18 Hankook Z211s. With 1/2" spacers in front and 1/4" spacers in the rear I needed to install longer wheel studs all around. My car is currently at the stock ride height so fender clearnace is not an issue at all. I might have a small problem in back so I'll either remove the 1/4" spacers or roll the fender lip.

 

I'm running the same offset +22 on 18x9.5 with 275/35/18 all around. My car is stock height so no rubbing issues. I did one trackday with stock camber settings and one with -2.7F and -2R. The car feels good this way and it has no understeer, on the contrary, it rotates rather easily on corner entry. This weekend I'll be dropping it 1".

Looks like no one has your exact setup in terms of width and offsets though.

 

so as a test fit,i put my 19x10.5 +22 CE28s on the front with 275/35/19 T1Rs and it barely cleared the inside suspension. i put a 3mm spacer, and it was just right- as for the clearance on the fender side, i'm am dumped currently and have a single finger gap if not less.. i'll probably have to raise the car up for sus. travel.. hm...

right now my current front wheel is a +15 18x9.5.. i can definitely fit a 265 there... hmm. maybe no need to go 10.5 in the front....

 

I run 17x10 ET25 w/ 275-40-17 because it is a little cheaper on tires I run a 3MM spacer in the front to give more wheel-to-suspension upright clearance...
However with an 18 wheel this likely will be less of an issue.

However I luv the balance the car has now....

 

Chebosto...what wheels are you looking at?

 

i currently have RE30s, 18x9.5 +15; 18x10.5 +18.

i was thinking about getting another pair of RE30 18x10.5 +18 front (they have a +25, but that won't clear the front suspension) or a pair of TE37 18x10.5 +22 just to even it out all four corners.

i threw on my LE28N 19x10.5 +22 with 275/35 T1Rs and the inside wheel cleared the suspension arm, and was flush with my fender. i put a 3mm spacer on (for effective +19 offset) however the wheel sticks out past the fender, and the only thing sitting inside is the tire. looked nice.. thats for sure. i only did one side since i was in a hurry, but i'll try to do both and drive around with it.
