The rotor shouldn't be making contact with anything other than the misc seals (apex, side, corner, etc). If it is making contact with the epitrochoid, then you have other very serious problems... I do think they will be too light for street use. I'm curious to see what the dyno says and what the RPM response rate looks like both on accel and decel.

I wonder how light they'll actually seem in regards to drivability. People go from a stock flywheel (17lbs?) to one under 10 and are fine with it. I'm sure due to differences in inertia, center of mass, and other stuff I don't really understand it's not a direct comparison, but the question remains the same: How much will shaving 5 lbs off the engine's rotating mass affect drivability?

I believe it's more of a concern with the rotor touching the irons, not the epitrochoid. If all is clearanced, shouldn't be a problem but if not that is when galling starts.
