has anyone ever
I have cross drilled and grooved Black Diamond discs, no problems with them. Hundred times better than standard. They do tend to be a little noisier than standard because of the grooves, but I don't mind. Just check the spec and size of the ones you intend to buy as they seem a little cheap. Mine cost me £180 and that took me a while to get the price that low. Sometimes if it seems too good to be true then it may well be. Good luck
