i got some DBA 4000 Series Rotors about a month ago and my buddy with a 240SX said that mine are backwards cuz he just rotated his around. he said he saw it on Hot Rod TV. When i got the rotors, they had clear left and right stickers on them, but my buddy says the difference is like night and day.

 

IIRC, the direction of the rotors depends on the inner cooling vanes.

Check with the vendor or DBA themselves. What was your friend basing this on?

 

he said the slots should point the way the car is moving.. i dunno. i mean, if the rotors had clear L and R stickers on them, then im sure its fine

 

i lined up the retaining screws on mine..

also the Racingbrake even said which was which and the retaining screws did line up. lol

 

i have racingbrake also, and my vanes point forward, however i would check with the manufacturer for the final word.

 

i left those out. was a PITA to take off

 

ill email them and see what the say

 

i have a clicking noise when i brake with mine....wish i could make it stop only does it when i brake....sounds like a fast clicking like the slots are ....i dont know...its just a noise....any suggestions? posted this b4 and someone responded and they had the same noise...i wonder if thats just what it does any suggestions?

 

Rotors with curved vanes should have the vanes pointed forward. Slotted angle doesn't matter it's the vanes that cool the rotor the most. The slots help a lot, but without the vanes the front rotors would toast up fast.

 

By Your left and right did you put them on the car with the Left side being the drivers side?

The slots should go on in the direction the Manufacturer recommends. Usually they slots go Front..\ and not Front /

And jjashaa what does the retaining screws have to do with it? Left and right are the same and the rotors can go on either side.

 

my slots are like this \, but my friend said they should go like this /. the car brakes fine. im gunna laugh me my buddy says fml, my brakes are toast. i just got off work, so once i get up and going, ill pull the wheel off and check the vanes just to be sure..but if they have been wrong for almost a month already, im sure i would know by now lol
thanks for the input guys

 

i dunno. it was just lined up when i installed them how racingbrake told me to.

 

mine r like this / dunno but i was doin 65 in a 40 and had to brake quick....breaks heated up and become real mushy...after they cooled of they were fine...turned the rotor blue tintish my girl noticed that

 

<--direction travel / direction slot inside to the out maybe im wrongge if so that really sucks...went through hell put in the bitches on lack of tools and a place to do it

 

I really doubt you would notice in everyday driving.

 

My RB rotors grab better when they are hot (they really bite).
