Really all you need is a custom upper arm that will clear the coil on a coilover, a normal shockmount on the lower arm, and add a normal shockmount to the top of the shock tower.
well, that and a pair of coilovers and a few sets of springs to make sure you have the right spring rate.
Take a look at the Camburg 6.0 setup and that's basically what you want, but for a lowered application. The camburg 6.0 kit only runs 1500 bucks for parts, and you get a new spindle, upper arm, bilstien shock, limiting strap, brakelines and NO BALLJOINT up top!
