You don't want a brass bushing in either of the clutches. They dont slide as well and will bind up more so than the factory PTFE style coated ones. I'd actually pay more money for the coated bushings if it were me. The coated bushings slide much easier and do not bind like brass or oilite type bushings. I've tested this stuff on the track on the timers and on the RacePac data logger. Longer bushings bind easier along with brass bushings when you put them in either the primary or secondary movables or the covers. The best thing the factory did was cut down on the width in half and coat the bushing in the PTFE coating. They were all the rage for a while when the aftermarket was pushing them, the concept seemed sound, but the results were horrible in the field for consistency.
