I noticed some people installed thier brake rotors two different directions. Also I've have seen it in many import magazines installed this way.

Here's my front driver side rotor (front of the car is to the left)



Other user's brake rotors are installed with the slots (lines) on the outer portion contacting the pad before the inner portion of the slot as the wheel rotates. Is that correct? Do I have mine on backwards?

If so, I noticed many users have it the both ways. (see this thread: https://www.clublexus.com/forums/sho...threadid=77866)

ps. my rotors were not marked left and right

thanks for the help.

Per the StopTech FAQ page, manufacturers differ in their strategy.

So the answer is that it depends on the brand of rotor. The direction of the internal vanes is more important than the direction of the slots or holes.

I was just thinking about this same question earlier today. I noticed my Stoptech's have the pattern going forward, and the powerslot rears have the pattern going towards the rear of the car. I know I intsalled them correctly, so like said before, it must vary by manufacturer.

I just purchased some generic cross drilled rotors off ebay and was wondering which way is correct..

From the stoptech website:
End of story..it looks like it has nothing to do with the direction of the slots. ..it's dependent on the direction of the internal vain.<which needs to sweep toward the rear of the car.
