I definitely agree that I would prefer a progressive spring for the street. However the M50i springs and every other factory spring I have personally seen are linear including the ACS lowering springs I bought. It looks like from the picture those H&R X6 springs are also linear. |
Appearance can be deceiving.
Not all progressive spring looks like what pictured progressive spring in your picture.
