Camber kit... horrible noise

I've had my 98 Accord lowered for about a year now with H&R sport springs (1.5" F, 1.2" R) and Tokico Illuminas. I never had any problems with my setup except for the fact that I wore the inner part of the tire out really fast. So I finally got around to installing a camber kit today. It wasn't that hard and I was really happy because after I got it aligned, the camber was perfect. But after leaving the shop and driving for awhile, I began to hear some nasty "thumping" noises when i would go over bumps or hit a reasonably sized pothole. The thing is, I've driven on these streets with my setup for over a year now, and i never heard anything going over the bumps but now that I have the camber kit, it sounds almost as if the car is bottoming out or something is hitting against something else. Can someone please help me as I have to drive back to college on Tuesday and I have a limited time to figure out the problem and get it fixed. Oh, I used a SPC camber kit. HELP!!!

go back and make sure all the bolts you removed to install the kit are tight. if done by a shop...take it back to them...their labor should be warrantied.
