^ Chris they be teachin' you good shot =) IF I had the money I'd get a 2-piece rotor setup w/ an aluminum hat for sure. This allows the disc to expand and contract w/ heading/cooling w/o cracking. Most of the time blank 1-piece rotors crack from thermal expansion etc.

 

I haven't started the motorsports classes yet..

 

I didn't clarify earlier, but that's what we run on our 240z (aluminum hat w/vented willwood rotors and 4 piston calipers). We also run performance friction pads. One thing i wanted to mention was i want to make it clear that these pads are horrible for the street because you will rarely get them to opperating temperature. i.e. they will transfer pad onto the rotor and then they are pretty much worthless. At vir i will ride the brake pedal for one full warm up lap to get the brakes up to the necessary temp.
