I am getting a FULL kit for my E36 in the next few days. Currently I have got Powerflex but they don't offer anywhere near as many bushes as the Superpro on the rear of the car. I have opted for the 80K (race spec) bushing with the front wishbone rear bushes that offer more caster on the front wheels.
I will be writing my experiances with the move over to Superpro from Powerflex with being as honest as possible with the bushes, how they fit and more importantly how they perform compared to Powerflex.
So watch this space
