They are mostly just pretty. $800 in Eradispeeds will not help your car outbrake my car with $60 Brembo OEM rotors and Carbotech Panther Plus pads (but Baer will have you believe otherwise). It is the manufacturers way of seperating you from $800 that would be much better spent on other parts (if race cars use it, or used it, it has to be good for my street car, right?). With that said, we have run Wilwood slotted rotors on the AIX car (because that's what Wilwood makes in that size) and those (that use a series of very small, overlapping, slots) seem to hold up pretty well. But, for a few hundred dollars each (not including the hat), they should.

Another thing I beleive is that if the slots and drilled holes are actually CAST into the rotor, then cracking is less likely to occurr. I'm not sure if that's how Baer does it, so maybe that's why they have no problems.

I'm happy I went with the powers slots. I paid $166 for the front, so I'm not going to worry much.
