I currently am running 18x8+51 in front and 18x9+63 in the rear and it has a good bit of camber in the rear lowered on TEIN Flexs. I want to swap in other wheels which are 18x8.5+40 18x9.5+40 and am currently running 255/40/18s in the rear. Right now the 9.5s wont fit even with the rears rolled and the bumper tab being relocated so I need to dial in some negative camber. How would I go about doing this? Do I have to get a camber kit?

 

If I'm not mistaken, if you went with the proper sized 255/35-18, you'd get a half inch of clearance.

 

I am actually putting the proper tires on before they go on, but just wanted to know if I can add more negative camber incase i need to.

 

I've got 245/35/18 on 18x10 +43, Tein Flex as well, -4 degrees camber without a camber kit in the rear, fenders rolled and car sits with no finger gap in the rear, no rubbing. If my fenders weren't rolled, I'd have rubbing issues.

 

How did you change the camber?

 

alignment shop.

 

The S2k gains camber as the ride height decreases. If you are dropped a substantial amount, you can obtain quite a bit of negative camber in the rear. Here's a graph of the camber with respect to ride height. The camber adjuster was NOT maxed out during these measurements, i.e., more negative camber is possible. The dashed line represents stock ride height.

 

i work at an alignment shop. It is not exact or even close to exact when doing it in your backyard. Go to an alignment shop so they can set it up to your specs. In my opinion, -3 is too much because it'll kill your tires. Recommended alignment specs are -2.5 or -2.25 i believe. function>form

 

Doesn't toe also affect camber? So just merely ride height alone isn't enough to determine adjustable camber range I'd imagine.

 

Yes, toe does affect camber. I believe I was using 1/4" total toe in when I took those measurements. The camber range will be similar for someone using reasonable toe values. Less toe in = more negative camber. More toe in = less negative camber.
