drilled rotors patterned in same direction

[jonsaudi]

I just got my Zimmermann cross-drilled rotors. Apparently I just noticed that the rotors are patterned the same way, in other words the direction of the cross-drilled are going two opposite direction..most of you probably know what I mean. I believe the driver side is right. Should I get the other one replaced? Does it matter which way the pattern goes?

I got the same zimmerman rotors, and mine was the same as your, I called MJMautohaus and they told me thats how zimmerman makes thier rotors.... so its fine

[jonsaudi]

Right on. Thanks.

arent the holes aligned with the vents in the rotors? so how would a left brake work for the right side???

watching this one, i just got mine btu don't remember how they look I will have to see when I get home and I will let you know.

if they are factory replacements that have been drilled, they are non directional vents... mine are ECS but have the holes and slots swept back but its just for looks... zimmerman uses the X drilled pattern which looks the same either side.....

it would only matter if you had higher end rotors like alcons/stoptechs/brembos or some ECS two piece rotors that are directionally vented

My RS4's are same-same...

^^^ just what I was going to say.

direction doesnt matter

direction doesnt matter

on non directional vents it doesnt but if you have directional vents, and put them on backwards, you will pull more heat into the rotors! take stoptechs, they appear to sweep forward (with the slots whereas mine sweep back) but you HAVE to install them sweeping forward because the vents are designed that way..... i remember one guy put his entire stoptech BBK on backwards because he wanted the slots to look like they were swept back

[aaronz]

mine go in the same direction

[Papachristou]

yeah, yours are one piece uni directional, usually two piece rotors have directional vanes
