my tyres are rubbing on rear arch
just sone advice please is it best to cut the arch or role the arch
i just purchast a roler anyway

but i have an over fender over my stock arch i did bead the lip up with a mallet in past
the only pic i have at moment is this 1

 

Since I tend to corner fast instead of driving like a Corvette owner, I run -1.2 degrees camber in the rear. If you are running stock rear camber, go more negative. Or raise the car up a little which will also require a realignment of the rear.

Hard to tell with your view. What size tires, camber, and ride height?

 

Did you roll your arches yet? Rears will roll flat with lots of heat and patience as they are double thickness,I would try that first before you start upping ride height.

Just looked at your pic again are you rubbing on the over fender? or stock arch?

 

Beauty looking set up!
Would you take some pic's of and tell us the sizes of your tires wheels brakes and ride height?
I am curious if you have the mythical aftermarket BBK with e brake.

The set up I will be running this year looks like it will be near identical to you, minus the mythical e-brake
