Colin ..... my racer uses Triumph GT6 discs ..... but they're 'skimmed' from 13mm thick to 7mm .... brake man was slightly taken aback to be asked to do that ... and at the bags of swarf chippings that came off .... then once they're drilled they're suitably light 🙂 .... his machine skims both faces simultaneously, which he claims is the way to go for trueness.
Is there any benefit from getting the Mog discs drilled?
