Read that PSA very, VERY carefully.
Then, order some poly (for street usage) or delrin (which is what all the Big Boys use!) spindle bushings; I'd go Prothane black instead of my ES blacks since Prothane impregnates the poly with graphite, but you do you. (I have Energy Suspension because I didn't know that. They don't squeak, but eh.)
For the inner LCA bushings, poly or delrin. Delrin again is what the big boys run; poly can take a set it seems.
