hey guys i got my rotora slotted rotors and axxis ultimate pads put on last week and now someone told me the slots should be going like / and not like this \

look at this picture and tell me if that's right!?!

btw that's the front passenger side rotor....

I *believe* it's correct. The rotor will be spinning clockwise in that picture...

BTW, nice job on the painted calipers.

Looks right to me. The direction of the slots need to go with the flow (which it is), not against the flow.

Cheeers !!!

thats correct

FYI

According to the Brembo site, the rotors should go the other way...

But at "street" speeds I doubt one would notice a difference.

he has the straight vane, which are usually non directional, but i guess i would check to see if they are directional

Hey Honda 99, goto rotora.com homepages and take a look the the 350Z rotors, they are mounted the way i described. Look at your box, see if they say left and right on them.

I think that it would make a difference, if it didn't really made a difference i doubt brembo would state it. You might get accelerated pad wear or the flow of gas disapation will not be affective.

Yes, straight vaned doesn't matter about direction, but if you read the brembo, it says all slotted are directional no matter if you have straight vaned

oh well i guess it wouldnt make a big difference anyway and i've seen more pics of them the way i have them than the other way... and it looks better like this... and braking power is VERY GOOD




@cUr@-TL

How does one paint their calipers like that? What kind of paint is used?

Nice work, @cUr@-TL!

They are mounted wrong...the slots should be going in the other direction.

thanks for the compliments guys!!! i appreciate it


now, what are the effects of having the slots going the wrong way?! will they cool down as fast as they should? will they warp easier?! would they brake better if mounted the other way?!

thx

@cUr@-TL

i think u might wear down your brake pads earlier and you won't get the performance u were expecting.

Actually I was watching a program the other day and they are correct. The way you have them is the correct way.

LOL who should i trust now :p



@cUr@-TL

To be sure call the manufacturer and he'll be able to tell you for sure.

Dude its wrong. Quit letting pics off the internet mess you up. I mean if you think it "looks cool" than by all means... I got the same rotors... still in the box. The box has labels stating which side they go on. The packing slip also shows different part numbers, and specifies which side they are for. The slots are supposed to go " / " according to your post. Good luck in realizing the truth.

If the inner vanes on the rotors go straight out, and are NOT directional, then it does NOT matter which way they go on. The rotors wont overheat either way

The whole idea about mounting rotors with directional vanes properly is for air flow/cooling purposes. Since these rotor vanes are non directional and go straight out, it doesnt matter which way you mount them as airflow will be the same.

In this case, with non directional rotors, mounting them so that the slots fall forward toward the front of the car is beneficial for better scrubbing of your brake pads. On my car I have the rotors mounted the other way. I wouldnt chanhe yours though unless you noticed any wobble from uneven brake pad distribution.

Here a link from Baer Brakes themselves.

ok guys if i decide to get them mounted the "good" way (with the slots going like this / ) will i have any problems?! i put about 350miles on the speedo since i got the rotors put on and i thought maybe one side wouldnt be the same as the other side (braking power or whatever) and might cause the rotors to warp or something?!

i need to be sure it wont affect the rotors before i get them put on the good way...


@cUr@-TL

The VANES are the slots inside the rotors and they may or may not be directional.

The SLOTS are on the wear surface of the rotors and are directional and the Baer and Brembo links indicate that.

By the pic in the original post we can determine the direction of rotation only by the slots, we don't know what the vanes look like. Of course, if the vanes are made in a directional design then we can only hope the manufacturer cut the slots to match!

Again I wonder if at the low speeds that we normally drive at can we tell if the braking is really improved or is it placebo effect? Has anyone measured the stopping distance with stock brakes and then with the new rotors? At racecar speeds I think there would be a degradation in the braking performance if the brakes were set up incorrectly.

I'll admit that I put drilled rotors on my car (as my signature bears out) but I like the way they look and they work just fine; I didn't put them on thinking my car would have the stopping performance of an Indy car.

I'd say that if the rotors haven't been on the car too long (the pads haven't been "bedded") then by all means switch'em if it makes you feel better, otherwise just leave'em as they are (I recall you saying you were happy with the braking performance).
You'll see that when I posted my original reply I prefaced my comment with "FYI".

Just my 4¢

someone tell me what to do :p im lost!!! lol


@cUr@-TL

Just leave them be...

nothing wrong with it.

Dude its simple find out if they are directional. If they are change them now since you haven't put alot of mileage on. If they aren't directional then you are fine.

My rotors are mounted "/" this way too. I followed the box labelling (please note the last 2 digits of the product number):

The front left rotor show part number as 168.40046.01 and the front right rotor is 168.40046.02. The Rotora box (for the front rotors) doesn't specifically state left side and right side. But the rear rotors do - it is labelled left (.01) and the right (.02). So applying the logic that .01 = left side, and .02 = right side, the front rotors should follow the same format. Hence the proper fitment is to have the slots going this way "/".

But as Mr. Hyde mentioned, it shouldn't matter. So if I were you, I'd leave it as is (unless it irritates you and you have to have the rotors on the "right" way).
