ha, no problem... is this going to be a pretty much track only car?
or half/half?

if it isnt a dedicated track car, id say order a energy suspension hyper flex kit.
i just got mine for 120$ shipped, and it replaces pretty much every bushing with polyeurothane.
and youll have a couple left over, like the t/c bushings, and endlinks.

now, if its going to be a track car, with little street driving, get something like jic, or tein rear upper control arms, lower control arms, and toe links. and you might still have a few bushings here and there to replace. but it will handle alot better, just wont be as forgiving as the e/s kit. (which is still very stiff.)
subframe spacers will stiffen the ride, and have less give also, but i dont think they will "fix" the problem youre having.
