cutting the stock pads and using return springs works. If you can get your hands on the KM racing bits they work well. I have been using Mugen MBX6 brake pad material. I hear good things about the Capricorn pads too, But I can't say because i don't have personal experience. I am liking the xray optional disc with mugen pads. The stock disc had the vents that once worn would grab a bit 4 times per rev. You don't have to get the other disc, but the mugen pads make a decent amount of heat.

Cheers,
