I just fitted a set of rear camber shims and 1 tyre rubs the arch over bumps
Running Escos wheels wih 215 40.
Was fine before even with a car full so its amazing how a 5mm shim can make so much difference
What do you guys do, trim the arches, roll them ?

 

This does seem very strange I run these on my 2wd saph with no problems at all where did you get these shims?

 

It could be that the rear beam/diff is not centred under the car. I found the same problem after fitting a new rear beam and arms on mine. I loosened the beam mounts and centre diff mount, pushed the beam across to the near side and tightened up the bolts. It will only move a couple of mm but it was enough to stop my tyre rubbing on the arch.

 

These shims
I had no chance but to trim the arch a little and remove the inner arch liners. The tyre doesn't rub anymore and the camber is corrected win win

 

Change the wheels , ecos wheels are ET25 ,way off the saff offset .

 

Has the car been in knock, maybe to fast in into a roundabout
