derling bushings

If it's a street car stick with the polyurethane bushings. The suspension system is bombarded with vibrations while the car is moving. The stock bushings are designed to reduce those vibrations a significant amount. Polyurethane transmits more vibration to the chassis but still dampens out the "hard" vibrations, or the damaging vibrations. Delrin on the other hand begins to transmit some of those more damaging vibrations to the chassis; which if in use on a street car can, and most likely will, lead to stress cracks at the pickup points and eventually mount failure. Delrin bushings should be kept to the race cars, or the street cars that aren't really street cars.
