Drove it for two weeks since what? Can you be a little more specific, and provide what modifications have been made (if any) to the suspension?
I noticed that my front was sitting crooked after I dropped my 96 sedan on lowering springs. It was at least an inch lower on the passenger side. I assumed it was the cheap springs I had installed so I decided to buy some coilovers... but after installing the coilovers with the lowering perches set identically, the car still leaned about an inch lower on the passenger side front. I still don't know what the cause is, but I know for sure that it's not my coilovers. Probably some kind of frame warping from an accident. But I would check things tire pressure too, that could cause a discrepancy.
