just found them on ebay and apperantly two sellers are selling the same items.,...
any chance that they are real? if so, will they eat up pads more quickly?

Don't think they are genuine. They will probably be more for looks than anything else. Don't know about pads as you would have to have them for quite a while before you noiced anything? Brembo on their site does not even list a disc for the X

sorry to correct you, but

they do provide upgrade rotors~~:cool:

Typical company see I went here

They do not even have a drop down for the MDX?

That's pretty cool- brembo has a new product line:

SLOTTED and DRILLED rotors...

When one is not enough!

Anyone know what the slots and holes are for/ (otehr than looking cool?)

So, real brembo or what?

Plus, why spend so much more on what amounts to stock brakes with LESS stopping power?

The idea is (under extreme use mostly) the slots or holes allow the gases, produced from pad/rotor friction, to be pulled away. This in theory allows for more actual contact during breaking. One benefit is they help cool the rotor also.
Some early "cross drilled" rotors were prone to cracking. This was later found out to be because the holes weren't countersunk. Slotted rotors are supposed to offer the same benefits as cross-drilled, but are less susceptible to cracking.

Exactly right on the gasses. Under extreme braking the gas actually would separate the pad from the rotor and reduce friction.

But the slots and holes REDUCE the surface area- thereby reducing braking. You overcome this by incresing the swepth area- but not so with these "stock" sized rotors. They also reduce the thermal mass of the rotor, so they heat faster. From what I've read they don't add much to cooloing as the holes have little airflow.

And the cracking is also related to when the holes were drilled- before or after heat/cold treatment. The rotors need to be stress releived after machining. Beware aftermarket jobbers sho take no-name rotors and drill them and put a name on them.

Any thoughts on how these brembo rotors have holes AND slots? (No other brembos do... as far as I can tell)

I think the material that the rotors and pads are made of also play important roles here, not just the size of the surface area right?

These rotors are made by Brembo.
However, the Brembo-made blank rotors are then custom drilled and slotted by the company called "SportBrakes" or whatever.

I spoke to the company before and confirmed this.

Somewhat true- there are multiple variables. I personally beleive the metal of the rotors is one of the smallest pieces.

Look at the area of a brake pad. Superimpose it on the slotted/drilled rotor. The are occupied by holes or slots is now no longer slowing you down. The pad material will need to change to increase the friction and replace this lost surface area.

But why? Are you tracking the MDX and using pads with such high organic content that trapped surface gas is causing fade? of course not..

You can change pad material to increase friction (and increase wear and dust) and do quite a bit before you need to worry about slots and holes. Next step is to change to a BBK...engineered for the mdx's ABS and proportioning system.... or just buy a BMW or Porsche and let the wife drive her MDX

Our MDX
got the idea

Thanks ardvarkus
