I've got Skunk2 camber kit which has +-4 degrees. My tegs dropped around 2 inches and the negative camber on the front wasn't that drastic before I adjusted it. The G3 integra doesn't need a camber kit in the back for that small a drop. If you're running on 14 or 15 inch wheels, then the tire wear isn't going to be that significant, but if you really need to straighten out the front wheels, then all you need is something which does minor camber +2 degrees or less. Note: autocross racers adjust their wheels for a lot of negative camber because it gives better traction in turns.

Also, a camber kit isn't going to do any damage to your car. All it does is allow you to adjust the angle the wheels face outward. In fact the Skunk2 camber kit is basically a replacement for your A-arm which has a moving slider you can adjust and tighten.

If you drop low enough to need a camber kit in the back then there's a simple way to do it which costs less than $5. You just replace two bolts with longer bolts and slide on 3/8" washers to adjust the angle of the rear wheels. Most people do it this way, unless they race and have to adjust on the fly.

P.S. Doesn't anyone use the search button? I swear there's 3 other threads on this one page in which I said the same thing.
