In the lovely weather on saturday i decided to get my vxr brakes out of the shed and give them a good clean. Now the fronts look straight forward to fit, but looking at the rears Ive got the calipers, dust guards and the back plates. I've been through carl threads and only see a detail brake down for upgrading the rears to vectra vxr brakes. How straight forward is to fit the astra vxr brakes on the rear? Do i need to mod the plates? Get different flexi? Mod the handbrake?
