direction of slotted rotors?

hey guys i have an 2002 SVT focus and i just purchased a full set of Rotora sloted rotors and ebc green stuff pads, my question is this, say your on the driver side of the car looking at the brakes are the direction of the slots supposed to be toward the front of the car or the back of the car


heres how they are now (ford did em)



front /// ///back (driver side view)

is that the direction there supposed to be or are they supposed to be \\\ that direction towards the front of the car? thanks

you have to check what the manufacturer says. the powerslots my brother had me put on his cavalier said to go the opposite way that you have them...was there anything that came with the rotors that might indicate their direction?

I don't think that it make much difference. As long as the gasses have an avenue to escape out from under the pad, the should work just fine. I could see some benefit to having them slot backwards, so as to use the motion of the rotor to encourage gasses to direct themselves outward from the center, but I really don't think that that factor is very important in comparison.

thanks guys, thats what i was thinking because of the centrifical force of the rotor spinning forward slings the gasses out. you pay alot of money for somthing, you just want to make sure its done right, thanks again guys

I was looking at a friends Porsche 911 and the bottom of the slot is is forward (to the front) of the the top of the slot to the rear on both sides of the car (like HaveBlue's photo above). They are directional on that car. This seems logical since the vent will cut into the air and expel it to the rear. Since slotting is primarily used to clean the pad surfaces and not expel gases this seems to be the best way to get the crud out quickly. If they're marked ...well ...heck its a no brainer!

I've seen them installed both directions, but from what I gather from people that have done them most of them have something that tells which direction to put them.

I wouldn't want 'L' or 'R' stickers... I'd rather have a 'D' or 'P' sticker. You could be at the front of the vehicle and the left side would be the passenger side, but it would be the driver side if you were at the rear. Sure you could have a right hand drive car... a diagram would make the most sense. Gonna stop before I confuse myself!
