[s-cars] New H&R suspension setup!!! Problems!!!!

[Levent Cur]

Ok guys finally got the car lowered. I used H&R 29800 springs and koni 
adj struts. The car rides perfect doesn't rub or anything, aligned well. 
But the left rear sits 3/8" higher than the right rear!?!?! What should 
i look for, what gives?  I'm so lost, i really like how it looks, and 
wish the car wasn't uneven in the rear like that! Any insight?
