This rotor replaces my stock wave rear rotor. The finish has excellent cross-hatching and looks great. Run-out is very precise and the braking feel right away is very good with fresh pads. The bolt holes are a little larger than those on the stock rotor, so the rotor doesn't index tightly on the hub. Also the counter-sinks are shallower than on the stock rotor so the bolt heads stick out a little bit more than stock. This is causing slight interference with my Enduro Engineering disc guard carrier. I expect to have a satisfying long service life from this product.
