Default new RS3s what camber??

My dunlops seemed to work best between 2.8 and 3.5 degrees of camber depending on the surface, springs sways etc...been loving 3.5 lately.

Any experience on camber, pressures and max temps before reduced performance (aka when they get greasy)?

Thanks,
Rob

Ideal Camber shouldn't change a whole lot from star specs to kooks as they are comparative tires. But the best way to check is by using a pyrometer, after you take a run or two look at where the heat is. It should be in the range of +-10 across the board ideally. If the inside is getting significant heat vs the outside reduce camber, if the outside is significantly hotter induce camber, and so on. temp wise, 150 is solid. over 180 and it's probably going to start getting greasy. I like this range, others will have other inputs. 140-180* I usually spray in the 170's so they don't go over 180. The kooks like heat, but they are still a street tire. Pressures will depend on what you are driving. IE weight of the vehicle.

Thanks for the input.

I'm trying to get a solid number out of the gate to minimize adjustments due to temps and wear. If someone has worn out a set did they notice significant inside or outside wear? What camber made for even temps for people? Specifically did anyone notice any bad habits for the tire with any pressures or cambers?

Car's going on the alignment rack tomorrow, educate my decision...

FWIW myself and an experienced STR guy found running RS3s required more negative camber and higher pressures than Star Specs though neither car was a Subaru.

^Same goes for the s2000 crowd. Most guys find they need about an extra .5 of camber compared to other similarly classed tires. Even more if they are running a lot of tire on a more narrow wheel. I know one guy on the boards is running 255/40/17s on a 8.5" rim and even at -3.5 he's still getting more outside wear. Different car but same idea.

Aren't they a bit softer in the sidewall? If so, a little more is probably more ideal.

I would concur on the S2K and Subaru front.

Cheers,
