x drilled rotors, did i put them on backwards?
 

Attachment 40964

Left Front 91 4 door

just wondering if they are backwards.. and if they are is there any harm in leaving them that way? i dont track my car or do hard braking.

i would say they are on backwards...will you notice? no....

honda tech says so aswell.. is it safe to keep them like that? i wouldnt think so .

you will notice nothing by reversing them.
...i have seen them both ways, we used to slot rotors for dech mustangs and they liked the slots swiping through the pad not slicing...better in the rain they said...take it for what its worth

alright thanks.. im gonna keep them the way they are. im not looking for ultimate braking power lol.. only a replacement for my warped rotors.

From Brembo's FAQ's ...

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. 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.
