I ended up getting a new cen bell cen gold springs and King heads mugen shoes. I hope they engage really snappy. See the reasoning for all the clutch questions is I have never ran aluminum shoes before I always used carbon. But I noticed that what I was using wasnt hooking up properly because my clutch bell would get burned, all the way around it would be purple. And I would dremel it off outside and inside weekly, and my carbon shoes dont even look used at all almost a gallon later. I do know that the coloration on the bell is from slippage and I dont want that no more. The TR is the only truck that ever happened to me with so I just attributed it to the weight of it. But now that I fell in love with racing it I went ahead and spent the $ and went to aluminum. What do I do for prepping the new bell and shoes before installing them? Robert I checked KMW but they are shut down right now, dont they sell different susp blocks and shock towers and a few other things for the TR?
