I'm using the Evo WC, with the aluminium pulley.
The K-factory's G4 disc is a direct fit to the EVO WC brake stopper.
Actually, I had to set the ATL in my radio lower because I had too much braking and this could make my rear belt brake easier. Plus, with the K-fatory pads there is no brake fading. The K-fatory pads also comes with springs so the pads are always not touching the disc when you are not braking, giving you more braking power when you need. The only "bad" thing is that this disc "eats" the pads faster than the original disc.
Give it a try when you can, you will not regret.
