Do slotted brake rotors really make that much of a difference?

From KVR, I think.
Enhanced Initial Bite
Intended For Track Use
Better Cleaning of Pad Friction Material
Slotted discs offer cleaning of the friction material (brake pads), but do little in terms of additional heat dissipation. Slotted brake discs do not cool better than cross drilled discs or even standard discs. The face grooves will slice the brake pad material allowing the pad to bite harder into the disc, therefore causing an increase in disc temperatures. This is recommended for competition vehicles to bring pads and disc temperatures up to optimal operating ranges. (Race cars warm-up engines, tires and brakes for the best possible performance).
Important Note: Proper slotting of a brake disc does not run off the outer diameter of the brake surface. This method can promote cracking as all brake discs expand with their release of thermal energy.
Cross Drilled Discs will last up to twice as long as O.E.M. rotors (depending on your braking style).
40% Better Cooling, 20% better stopping
Improved Wet Braking
Lower Brake Temperature Reduces Rotor Warpage
Less Brake Fade and Longer Life
Cross Drilled Discs offer an enhanced initial bite (more responsive, especially in wet weather) and greater heat dissipation (reduction in heat induced fade - "brake fade") as compared to O.E.M.

All I know is that I smoked the hell outta my Neuspeed/Mintex setup yesterday!
At the end of the twisties, after about 10 minutes of HARD downhill, twisty driving, they were on fire! They smelled something fierce, and were fading faster than bugbbq after drinking a 40oz.!
Up until then, the brakes have been just fine. I dunno what happened!

Yeah, mine were A-okay after that run...
But it was probably that I had a manual tranny to help slow me down. Long twisty downhills can be a bummer with auto trannies.
Next time we should start at the other end and go up. Much easier on the brakes.
