I've never bottomed out yet with the 1.75". It looks like it's too close but it's all good. Small coils face down in front and face up in the rear. Actually there is some sense to it. The small coils butt up against the fixed point on you suspension. If you look closely the fixed point in front is the lower perch. The fixed point in the rear is the upper control arm. Ahhh. See I have an answer for everthing. These Road Magnet seem like they are impossible to bottom out. Believe me I've tried.
