Some of the guys running the Penski/EMI/Moton type of suspensions also run a small helper spring with the mail coil on their suspension. Whats the point of this? I cant imagine that they do much. Also, wouldnt they just crush anyways and just add height to an already adjustable suspension?

Generally, a helper spring is a very thin (I mean FLAT) coiled spring that keeps upward tension on the spring. This is especially important when the suspension is unloaded, so the spring stays seated in its mounts. If it cocks to one side, it can damage the upper/lower spring mounts, which are aluminum.

If you don't have them, the main spring can lose contact with the upper spring retainer on the shock at full droop. The retainer may jam crossways under the mounting eye when the suspension compresses again. The helpers are dirt cheap - use them.
