my e46 m3 is on st coilovers and sits perfectly all around when on flat surfaces. i was parking up (front facing top of hill) on a hill and noticed that when the e-brake was pulled and i let off the brake the passenger side rear was sitting lower than the other three corners. So i turned the car around and parked it downwards (front facing bottom of hill) and the car was still sitting the same way (rear passenger is lower). Is it something with the e-brake that makes that wheel hold all of the vehicle weight? Any insight would be helpful.. thanks..
