Suspension Rattle??

[PaViper]

I have developed an apparent suspension rattle in the right rear over bumps. Funny thing is it seems more pronounced when it is cold, and seems to get less noticeable as it warms up. Any ideas what it might be. I have had the car on a lift and tightened everything that you can put a wrench on, and nothing appears to be loose.

If you still have the exhaust crossover I would bet it is the culprit.

No crossovers, Corsa Track....unless they let them hang there not hooked up
