New Rotors....Slotted and Drilled???

I have a set of the drilled and slotted 11.75 rotors on my son's '68 Dart. The only reason we went that way was because he wanted the "look". Certainly for the street they make no difference. On the track, where I'll freely admit I have no experience with this car, it might improve performance or cooling, and on the track they just have to survive the day, not 10, 20, or 40,000 miles. If you like the look and don't mind spending a bit extra, get a set from Brake Performance. They have a 2 year warranty and are reasonably priced. And yes, I'm sure they're an offshore brand....
