I have ordered 17x9 +62 rims with 255x40 all around. These are for my track days only. Will I need to get my fenders rolled if I put max camber front and rear?

 

Are you lowered any? If not then you'll be fine with just some camber.

 

I am on stock suspension, not lowered. So I should be ok, great!!!

I was thinking, maybe in the future, to add these, not to lowered the car, but to stiffen the suspensions for track days. Any opinion?

For a track car, I would go with coilovers for the gain in damping adjustment. There are plenty of affordable options; Fortune Auto 500s seems to be a popular choice lately. Even if it's lowered a little bit a minor roll will keep the wheels from rubbing.

 

Just installed the same setup. Slight roll will be required in the front if you decide to ever go as low as below. Should have no problem clearing on stock ride height.

FYI, running -2.8 in the front and -2.5 in the rear.

 

Awesome! Thanks guys!
