Heim joints will only make a difference if you are genuinely track racing your car.
Going to heims on the street is a good way to have the most uncomfortable, ungodly ride you'll ever experience. First hand experience from driving my buddies SN95 drift car.
I still have stock bushings everywhere on my car, save for the differential and the knuckles. And I throw my car into a drift at 80mph. They feel just fine.
I like the enthusiasm. But dont do that to a street car. Keep to the poly bushings from SCP if anything.
