Hi,
Slotted rotors are to allow the plasma which forms between the rotor and the pad to vent away allowing better pad-to-rotor contact. But, on a Street Car, it's just a gimmick, you really need to be on the Brakes hard and often for this to be a real issue - a dedicated Track Car.
Cross-drilled Rotors are dual purpose - Cooling, but mostly to cut down unsprung weight.
On Street Cars, both of these really only serve the aesthetic.
Either will wear your pads more quickly. Another Caveat is that neither s/b turned (machined) as this can further compromize their integrity. Most shops simply won't do them for both liability purposes and because they can wrech the shop's equipment - kills the blade end. Hope this helps...
Happy Motoring!... Jim'99
