FWIW...changing a brake rotor alone is not going to have much impact on the overall braking performance. You'll need a larger rotor to create more torque- think leverage. While slots, hole, dimples etc can all help enhance pad function there is simply no overall increase in braking by fitting a same-size disc to a system.

Money spent on pad options for improved bite will go much farther. By raising the Cf of the pad you'll get greater stopping torque. While fit to the same diameter disc.

Changing to a larger disc is certainly a preferred method of improvement but it comes only with a full blown BBK conversion.
