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.

Well to tell you the truth, I just got them for the I HAVE THEM factor. They look bad *** if you can get the big brake system. But I cheaped out and got the LX instead of the ES so I don't have the 4 wheel disk. But thanks for the coment.

Powerslot is the exact opposite. They have the inner (lower) edge of the slot or hole meet the pad first. That's why the one guy was telling me I installed mine wrong, because he was running powerslots.

hey hughes412, correct me if I'm wrong but the first pic you showed with the rotors alone has 5 holes but your car is a 4 hole. I take it that the rotors taken by themselves aren't the ones you have installed on your pro. Am I right?

Yea, I did them. Took like 20 min each. But I use to run a break shop so I am well rehurst when it comes to brakes.

Today 12:41 AM
Yea they were the wrong ones. I was so happy that I finally got them I never looked at the lug holes. I even picked one up and showed a guy at my apt. I didn't notice it untill the next day after I posted them, I was showing a friend at work the pics and I was like OH HELL NO! LOL
