This would be for the 1-piece rotor. DON'T get cross-drilled rotors. They're a total waste and will cause you to burn through your pads quicker.
Stoptech has a TON of pad options, plus it'll take you about 5 minutes to change pads. Very easy with this kit.
If not a BBK, definitely change your pads and fluid to high temp fluid before the track days. I realize you're only a novice, but nothing will ruin your day when you boil over your brake fluid or you start to push the car and end up running out of brakes.
The first thing you want to change/upgrade for track days is brakes. The last thing you want to do is add power. Pagid pads are stellar.
I've been driving on the track for over 10 years and have my SCCA Comp license. There's nothing better than going to hit the brakes and being sure that they're going to be there, lap after lap.
