4-link suspensions

4-link suspension advantages include no wheel hop, anti-squat geometry, increase forward bite, and allow the use of coilovers for infinite adjustability of spring rate and ride height.

It may weigh a little more than a leaf spring setup, but the advantages are worth it.  And losing heavy traction bars may more than compensate for the extra weight.

A full write-up on 4-links will be coming soon.  For now, check out:
