SRT8 Brembos

Are our brake rotors installed backwards? My mechanic looked at my chally yesterday and asked "who installed your rotors?" Of course I told him the factory....

He then told me that they are backwards. The slot should be pointing forward. Looking at other slotted rotor pics of many other cars, they are also pointing forward....

Its not a hard fix but... come on... seriously?! From the factory?!:roll:

This has already been addressed in previous threads. They are supposed to be that way.

The factory rotors are non-directional, and they are the same part number for either side - if you buy a set of fronts, you get two identical rotors - so one will always be oriented "backwards" from the other.

But they are straight-vaned (not directionally-vaned), so it makes no difference which side they're on. The direction of the surface slots doesn't matter.

So rest easy; yours are the way they're supposed to be.

Well... I apparently cannot find that thread... but coming from Brembo themselves.
Which direction should the discs rotate?
It is a popular misconception that drillings in a disc determine the direction of rotation. In truth, for an internally vented drilled disc, the geometry of the vanes dictates the direction of rotation. There are three vane types in use:
- Pillar vane (comprised of many small posts)
- Straight
- 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 the 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, 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.

Dude.....keep digging.Thats the way the factory did them,BTW......our rotors are not Brembo.....if you want Brembo rotors get ready to spend some money cause they are 5x the cost of our stockers.

Mopar didn't seem to get that I guess lol! Yeah, it's been addressed, heck even when i got mine a little over a 1 1/2 ago. When i got them i thought it was a mistake, but then i posted and got the same info you are getting now.

BTW, it's kind of weird seeing Erik now showing a 300C in his profile.. sorry for the ditch...

Yea... just found your post a ways back in a thread about vipers.

And did not realize the rotors werent actually Brembos...

if the car stops forget about it! Im trying to figure out why the factory installed my engine sidways!

....of course they are...you bought our product and we know how they are supposed to be. Bunk.



Crap! Oh man, now what do I do??

Here are a host of others who might disagree:

I stand corrected - the factory rotors are not straight-vaned; they're "Pillar vaned".

Never heard that term before, but it makes sense.

EDIT: the term makes sense, not necessarily the design. ;)

LMAO! Nice. Have you got them in stock yet? ;)

I like the deflection in that vid when they say "warp" - damn thing almost folds in half.

[ikonis]

you may be correct which way the slots do not matter. But I assume they should be the same on both sides of the car

On the passenger side they are with the slots facing forward whereas on the drivers side they're facing opposite. Like I have 2 sets of passenger (or driver) side brakes

The SRT engineers said that the direction of the slot on the face doesn't matter, so its easier and cheaper for them to stock 2 part numbers instead of 4. Of course we'd like them to match, but its not worth it to Dodge.

Damn beancounters! Thanks for the info...

That's really what it comes down to - the supply chain. There's no reason for them to introduce two parts into the system, if one will accomplish the same results - and in this case the one does.
