There's a Manchester company who advertise a LOT on eBay (Performance-discs or something like it). They buy in plain discs and CNC cut dimples/slots/holes in them. Since reading that drilled holes crack and aren't needed with modern pad materials and that dimples are only aesthetic, I'm going to see if they can do these:
It's 8 slightly curved grooves that vent to the outer edge of the disc. They're cheaper than EBC turbogroove discs and the feedback from guys with Porsches, big Nissans and Audis etc is brilliant.
