I installed my new drilled/slotted rotors but they look backwards to me...does anyone know if it matters which way the slots go...as in if the bottom of the slot should rub the pad first or the top of it should? Does that makes sense? TIA.

 

Yes they are directional most rotors are marked for left or right but right now Im brain farting and cant recall.

Try this there is one for direction with pics.

 

My GM ones went on with the slots going to opposite way, 'with' the wheel, if you will... My Stillen's went on like the StopTechs, but on my buddy's WRX, they go on the opposite was as teh stoptechs up there...
