I got the front on all good but the back are haveing problems. There is no way to tighten them. From where the top of the rear strut tower ends to the begging of the thread, there is a good 3 inches. It is so un drivable because every time I hit a bump (even small) my rear springs doesn't compress, the car just bounces real bad. I bough a box of washers to try and take away from the gappage but it still is bouncing as hell. Please help quick
