Slotted Rotor direction

[Adam Kielski]

Hey....
If you were ever wondering what direction the slots should face when you mount your new *bling*bling* slotted rotors....here's a link

Look at the last sentence of the 3rd paragraph.  
Basically the top leading edge of the slot should make contact with the brake pad first with the wheel rolling forward.

That will only work on one side.  The left and right rotor (if they are slotted the same) would rotate opposite of one another.  For example, the leading edge on the left side would be contacting the brake pad first, where as the trailing edge of the slot on the right side rotor would be contacting the brake pad first.

I' m not sure if I caught the wording right.  Either way...the picture on the top of the page of the rotor..would go on the RIGHT side.  If you buy a set of slotted rotors....they should have a L or R on them.

[Jeff Armstrong]

That makes sense then if they actually make L and R rotors.  Didn't know if they did or not.

I have always seen ones that are directional and left and right and sometimes there is only one way to mount the rotor it depends on the design but this isn't usually found in regular cars, at least from my experience.  Maybe the cheap ones that are more slotted for looks than anything are not directional at all.

[Adam Kielski]

There are L and R rotors....they are mirror images of each other.  This means that if you mount one side so the top leading edge hits the pad first then the opposite rotor will do the same.

Merlin....the picture of the Brembo rotor would go on the LEFT side of the car.   :?

well thats not how my powerslots mount......

how about x drilled?

I've seen the new mercedes, and the left one goes lead edge first, but right side goes oppesite...

It doesn't matter which way the 'slots' go, what important is the way the veins inside the rotors go. Some rotors are directionally vented, while others are just straight vaned.
Directionally vented vanes on a rotor act like a centrifugal air fan, drawing air from the inside of the rotor and flowing it to the outside. The vanes of a directional rotor should arch back like arms on a pinwheel. On the top side of the rotor, the vanes should curve toward the back of the car. If they are not installed on the proper side of the vehicle, airflow will be restricted and cooling will be severely diminished.
