Calipers Wearing On Rotors

[Fastrotor]

During racing at the bitumen Sprints, im noticing the rotors copping alot of wear from rubbing on the caliper (i assume). You can hear it when turning on the warm down (ie everything real hot) and the cars just cruising along so quiet. Once there cool you don't hear it when going out for the next round.

The wear is only on the rotor outer edge on the drivers side, and it was only there on the passenger side in the first round, but after last weekends event, its wore a good 15mm in from the edge and about 1/2 mm deep ! So i have to fix it before next round .

I assume this is wheel bearings ? When cold, there doesnt seem to be any play in the wheel when jacked up to test.

I havent had the caps off to check the bearing preload yet.

Anyone has this problem in a R33 GTST Mspec ? Got pics if needed

Just for posterity sake, i fixxed this problem by increasing the caliper shims to move it ever so slighly, as you could tell it wasnt 100% centered. About half a millimeter shim. Basically removed stock ones and had some shim washers about twice as thick.

All good and no more rubbing or noise.
