04 nsrt4. Car has 89k miles and is still on the original clutch. Needs a clutch fork. About to throw in a wikyd performance tob fork and an upgraded pivot ball. Contemplating throwing in an ACT HD-SS clutch and also replacing the rear main seal while I'm in there. Is that a good idea, or should I just leave the original clutch in there for now? It's not slipping at all as of the moment.
