Ok, after talking with people that have had these flywheel bolts back out, I'm fairly certain that this results because there is no mention in any of their literature of using loctite. Using red loctite with the spec'd torque should eliminate this problem. If you're really concerned, there is still no reason to overlook an aluminum flywheel if you really want one; you could always have the flywheel bolts drilled to accept safety wire. :dunno:
