Rear thunking noise in rear after lowering
I recently lowered my car using the prokit and installed 20 inch razors. Now I have started to notice a thuking noise in the rear of the car (passenger side). I have checked and everything apprears tight. Does any one have any suggestions. Please help.

RE: Rear thunking noise in rear after lowering
I used the pro kit too, I have thud on moderate bumps. I suspect the rear end is hitting the exhaust pipe where it goes over the axle housing. I drove into a Wendy's drive the other day faster that I should have and I heard a LOUD bang, might be the rearend actually hitting the rubber stoppers on the frame. The pro kit lowers the back by 1.9 front, 2.3 inches rear, and the car rides very harsh now. I may change back to a less severe lowering spring (but I love the look I have now)
Take car to a shop that has a lift that lifts the car by the wheels not the frame and take a good look, there should be some "wear" marks where things are hitting. It may be as simple as a slight adjustment to the pipes.

I looked under the car and it appears that the mufflers are not hitting anything. I did cut the bumpstops in half. Thanks for the information.

Check out the passenger side spring, it might be indexed wrong against the insulator...

RE: Rear thinking noise in rear after lowering
Check the clearance on the driver side where the over axle pipe runs by the panhard bar upper support. It may be hitting. I know you said passengerside but check it anyway. Also can you be a little more specific about your problem. Info such as when it happens etc... Asking about a noise and being vague does not help uswith trying to help you. The more info you can give the better we can help. Also do as the above said and check the sprng indexing
