I am having a bearing failure problem with this. I have a Mugen MT 12 with the RC10 clutch setup on it. I am using all AE parts with an MIP 4n1 clutch. The problem is I keep destroying the rear clutch bearing. After the last time it did it I put everything back on it brand new. I mean everything from the eclip to the clutch nut even a new flywheel all clutch related parts were changed. I even checked the flywheel with my dial indicator and only have around 3 thousands of wobble in the wheel its self. This problem been around for a little while and I am at a lost for a solution now. The only thing i have not tried was a different make of bearing in it. Currently I am using red seal bearings with it. I looked at the exploded views on the AE site and it appears nothing is missing at all from the assembly I am sure of that. I can get maybe 3 sundays of runs out of it before it goes out on me. It is just like the rear bearing is coming apart on me. I take it apart and the rear bearing just falls apart and nothing seems to be really broken at all. Heck it keeps it up might start to run the bushings in it instead of bearings LOL.
