I bought some straight vane slotted rotors from eludeauthority, but I don't think I got the directions from Brembo... can anyone confirm that this is correct? Anyone have other suggestions (I know some people claim that installing them as per these directions pushes the gases toward the hub and can be problematic)?

This says...
passenger side: // (rotation -->)
driver's side: \\ (rotation <--)

Just want to make sure before I install!


From Brembo FAQ: Brembo Frequently Asked Questions

"Which direction should the discs rotate?
It is a popular misconception that the slots or drillings in a disc determine the direction of rotation. In truth, for an internally vented disc, the geometry of the vanes dictates the direction of rotation. There are three vane types in use:

* Straight
* Pillar vane (comprised of many small posts)
* Curved vane

The first two vane types are non-directional, and can be used on either side of the vehicle. The curved vane disc, however, is directional. A curved vane disc must be installed with the vanes running back from the inside to outside diameters in the direction of rotation. Please see figure. Orienting the disc in the manner creates a centrifugal pump. The rotation of the disc causes air to be pumped from the center of the disc, through the vanes, and out through the outside diameter of the disc. This greatly enhances the disc's ability to dissipate heat.

Additionally, all of Brembo's slotted discs are directional as well, regardless of the vane geometry. The discs should be installed such that the end of the slot nearest the outer edge of the disc contacts the pad first. Please see figure."

EDIT: Tirerack seems to confirm this idea: "The slots are angled to use the rotors’ direction of rotation to enhance their performance, which makes the rotors side-specific with left and right side rotors. Brembo Sport slotted brake rotors are sold in axle pairs and the easiest way to verify correct usage is to install the rotors on the side of the vehicle that results in the end of the slot nearest the outer edge of the rotor always contacting the brake pads first."

whoops i do believe i forgot to include the directions with the rotors for you. but you do install the rotors on "backwards" as it seems so air flow actually goes into the caliper. sorry for forgetting to tell you that but it seems you figured it out on your own.



for reference the rotor on the left is the driver and the rotor on the right is the passenger!

Well, if the veins in the rotor are directional, then they have to be facing so they are not scooping the air. If they are just slotted with straight veins, brembo says the top of the slot at the top of the rotor is to hit the pad first.

Thanks guys. I did my research and I thought I was right, but I just wanted some people I trusted to ensure I was... I'm kinda OCD...
