Ive got a mk6 tdi , which I have fitted (myself) with mk6 GTI suspension. had it aligned etc, felt great.
about 5000km after, I am noticing a squeak from the rear - both sides equally - only when i go over sharp speed bumps, like the ones in shopping centre carparks.
It seems to get worse on hot days.

Any ideas? I think it may be from the struts rubbing against the bumpstops but the suspension is relatively new ..

the springs are on the guides perfectly, quick visual inspection didnt show anything out of the ordinairy

car also has a whiteline RSB for what its worth.

Cheers
