Auto-x stuff you will do just fine with the AWD 2-piston brakes which will bolt right up for ya and a good set of pads. I love my Hawk HP+ pads for street/track use.
If you are planning on doing some Lapping Day's or time attacks on some big tracks, I would recommend going with a TCE Big brake setup.
