teamrush ignation upgrade rotor issue

[gyvrr]

Anyone having issues with the rotor coming loose on the shaft? I'm finding after 1000 miles or so the rotor wobbles at the base of the rotor on the dizzy shaft. Thinking of creating a shim to install inside the rotor using a feeler gage. I've purchased several different manufactures rotors..... Same results. Dizzy fairly new and nothing seems to be out of tolerances. Anyone got a clue?

I know those rotors fit a bit on the loose side. I have not had any issues with mine though which I purchased at N.A.P.A. made by Echlin.
