So Stazi, are the rotors you sell well balanced? Do they set on the hubs with very little play?
The mysterious vibration I've had turned out to be my rotors. I used a piece of aluminum foil on my hubs to take up the clearance, I wrapped it on like to take to make up several thousandths, then stuck the rotors on. Made a night and day difference right off the bat.
All of this after I replaced a hub AND a rim!
I need really need a new set of all four rotors but my pads are actually pretty thick and they are the Bendix Titaniums.
