Advantages to slotted or drilled rotors? I don't think so.

With the right pads (not OEM), you will almost never have brake fade. Back in '93 (16 long years ago), this may have not been the case... Brake pad compounds have come a long way and easily operate at very high temperatures. Modern track pads don't glaze, gass, and for that matter don't fade as long as you don't exceed their design temperature. In my opinion, and I believe this to be very close to the scientific truth, there is absolutely no reason to have slotted or drilled rotors. Slots and holes cause many issues. They reduce mass and this resultantly reduces thermal compacitance; although they may cool slightly faster, they will also get hotter faster than solid rotors of equal size. The slots cause your pads to wear faster with no appreciatiable grip benefit and the holes cause stress concentrations which cause your rotors to crack if they get too hot.

Do the research, get the right pad (carbotechs seem to work great), and solid rotors are the most robust solution.

Just my 2 cents...
