Have done the lowering springs install this weekend.Have anybody else used APEX?Seen lots of HR and Bilstein combo from this forum.The physical length of the APEX springs compared with stock before installation is 1 inch shorter.With the springs installed I can only notice minimal lowered height of the car but the handling has really improved.Corners can be taken at much higher speeds with confidence where previously I wouldn't dare do.Steering response is improved much.No harshness at all but the overall feel of the car is stiffer.
