Hey all,
Whenever my car is "cold" (just started driving it after sitting for a few hours) and I go over a speed bump, I can hear what I can only describe as a scraping/grating sound coming mainly from the rear suspension, (though occasionly from the front) I'm thinking the shock absorbers might be worn, though I was just wondering if anyone has had this before/could it be anything else?

Also I was looking at the rear discs, and noticed they've got a bit of a lip (about 1-1.5 mm) at the edges where the discs run, how much of a lip is tolerable on the discs?
