Because I have drilled and slotted rotors, and they seem to be directional, I have to ask you guys: Which way do they go on? Should this one be on the drivers or passengers side? Tell me that, and I can figure the rest out easily enough.

 

one pictured would go on the passenger side

 

Think of the gasses being expelled in a centrifugal fashion, and it should be easy to figure out.

 

Thank you. Which means I get to go out to the car and swap them, LOL. I put 'em on the wrong sides.

 

oopsy poopsy

 

Oh well. At least I didn't drive with them on that way.

 

could it really do harm though???

 

gunk would build up towards the center of the rotor id imagine . . .

 

You would experience massive brake fade running them on the wrong sides.

 

wanna know the greatest feeling? its when u go out to your car to inspect your brake rotors for the first time since u bought the car (its been less than a week that ive bought it) and realize that u have slotted/x-drilled rotors. cuz thats wat im going through right now!
