Boxster S Rotors badly gouged after "Specialist" rear wheel bearing replacement

[DFW02S]

You should tell them to replace the rotor, the pads and the caliper. All parts have been damaged by their mistake. The pad and rotor are both scored and the caliper guard or stud (whatever they might call it) has essentially been sanded down to an out of spec condition. Go for broke, both sides need to be done.

strange; that actually looks like an S rotor mounted in a standard boxster caliper.

another alternative is that they didn't properly torque the axle nuts. this would mean the hub isn't drawn all the way into the bearing, allowing the wheel to 'wobble'

I'd guess the axle nuts aren't fully torqued, leaving the rotors too far outboard, and potentially having side to side play. It'd be almost impossible to change the alignment of the caliper, so I'd assume the problem to lie in the rotor.

Either way, make sure you get whoever did the work to pay for a bunch of new parts....
