I feel dumb asking this question after so long as i had thought that my rotors were on correctly. About a year ago I put on power slot rotors and i have the slots angled toward the rear of the car, and recently I took notice to a few cars at a car show that had them going the other way. Does it matter?? Seems it must somehow. Can anyone give me some info on these things?? Thanks guys

 

dunno if it matters, but it looks cooler if it goes clockwise on the driver's side and counterclockwise on the passenger's

 

I would assume it mattered, or PowerSlotted wouldn't have made "left" and "right" rotors. I know you have PowerSlots, but the theory for gas dissipation for slotted rotors should hold true for all slotted rotors.

Here's what the Baer website says about the rotors being directional. My guess is that it's the same for your PowerSlots.

Mine had a "L" on one and a "R" on the other, indicating which side to put them on. I can not remember off hand which way the slots are running.
