I've used delrin in older cars with no ill effects. As far as I can tell BMW missed the mark with the bushing combinations used in our cars. If they had got it right, we wouldn't have the massive wheel hop issue at the rear. I rarely get in situations that would generate wheel hop, but it's clear the bushing selections were geared more to ride quality than performance. That's fine in a 550 or 328, but completely unacceptable in an M3.
Dinan compliment of stuff plus PF rotors and RG63s. Enough for now.
Why, yes. I am an abrasive bastard.
