Well.............I thought I had read enough previous forums about upgrading the 124 brakes with 400E Calipers & Rotors. I have completed the 400E front caliper and rotor installation on my 260E and the right front rotor is now rubbing on the lower control arm! hummm? The car is driveable but I thought (read) this application was 'bolt on' It sure doesn't seem to be.

Any thoughts or suggestions would be appreciated.

Why would it happen on one side and not the other? Could you have suspension issues or a lower control arm that is out of alignment or bent beyond spec?
