Wow you did get some terrible advice in the engine subforum ... ignore it!
Agreed with Peter that track-oriented brake pads are a good idea if you have track experience. The OEM pads work - I'm surprised how long my lasted given how hard I abused them - but aren't in their element operating at very high temperatures. The stopping distances they provide just are not precise.
