First Specify what do you mean by brake? Rotors, pads, calipers? what exactlly?

As for rotors MAzda 6: Diameter: 274mm (10.7in) - Thickness: 24mm (.94in)

from http://www.racepages.com/performance/basket.php?makeid=16&modelid=289&year=2006&partid=78&brandid=2755&skipped_brand=true

Mazda 3 Rotors: 2.0L --> Front, Diameter: 278mm (10.9in) - Thickness: 25mm (0.98in)
--> Rear, Diameter: 264mm (10.4in) - Thickness: 11mm (0.4in)

2.3L--> Front, Diameter: 295mm (11.6in) - Thickness: 25mm (0.98in)
-->Rear, Diameter: 280mm (11in) - Thickness: 25mm (0.98in)

I think they should fit with no problem

I mean rotor/calipers/pads....

I am wondering waether 6 and 3 are like nissan S13/s14/skyline R32/R33.....the nissan parts are always bolt on to each other...

Those look like they're from the standard 6. I think the OP was asking about the Mazdaspeed6 brakes. Does the Speed6 have larger brakes than the standard 6?

I dont know if the Speed6 brakes will fit but I am investigating putting speed3 brakes on my 3. The calipers are different and I am trying to figure out if they will bolt up to the 04-06' front knuckles.

Oh, ok, well i do not know that. But why put MAzdaspeed 6 brakes to your Mazda 6 or Mazda 3?

Why put larger brakes on a car at all? To stop faster with less fade.

It looks like the Speed6 brakes are definitely larger than the standard, as well.

Mazda put big 12.6-inch ventilated front and 12.4-inch solid rear disc brakes on the Mazdaspeed6, plus standard ABS and electronic brakeforce distribution.

If speed 6 brakes could fit on a 3 that would be great.

One of the local shops here do slotted/drilled for OEM rotors. That would also be a good upgrade too.

::Sigh::

Drilled and slotted rotors don't help you stop faster, will not help you lock your wheels faster, and will not help dissipate heat any better. People drilled rotors decades ago when brake pads were crap, and had problems with out gassing. Slotted rotors will help wipe dust and debris off a pad surface, but they don't help you do any of the above better, either.

Drilled and slotted rotors aren't a performance upgrade, they're a bling upgrade. I'm sorry if this seems a bit rant-like, but this is one of my pet peeves. If you want good brakes (that actually stop the car) instead of pretty brakes you've got to go big.

thats why it would be great to get the speed 6 brakes. I pm'd RonTonkinMazda to get more information and prices if possible.

I can stop just as fast with 8" rotors as I can with 20" rotors. Larger brakes will not let you stop faster, they simply allow a larger thermal sump to suck up heat and slightly improved heat disapation (barely). Basically it just means it takes more and higher speed stops to soak the rotors with heat when you have larger brakes.

I have yet to have pedal fade on my 3i...of course I have not yet done any hardcore canyon running, I am sure I could manage it then. For 99.99999999% of daily driving bigger brakes would net you no benifit. Only if you do a lot of canyon carving or actual track racing will you see a benifit. Autocross doesn't last long enough to heat soak your rotors unless they are 3" rotors.

And actually in most conditions larger rotors will hurt your performance. It is just more metal to accelerate and has the disadvantage that you are both spining it and have to control it with a suspension.

At some point i do agree with you, but I dont, 50/50, why?

1. Driller rotors are very important on rainy roads or where it rains alot, as you know holes wont do much of an improvement but as Porsche Specialists claimed, drilled rotors only improve braking didtance when it rains, think why Lambo's, Ferraries, and Porsche's use driller rotors? In addition, drilled rotors will decrease rotor temperature at hard braking at really FAST speeds.
-1. Drilled rotors at some point, some day on occassion CRACK.

2. +1. Slotted rotors mostlly better to keep your rotors clean from dust and dirt.

As for increasing braking distance with LARGER rotors, calipers, and pads i 100% agree it will significatlly increase braking distance, but tell me this, i have purchased Brembo rotors for my old Corolla, Cross/Driller, and my braking distance increased by much greater distance?, and they were OEM size.

Aside from the 8" vs. 20" example (unless you're talking about the case where you keep the calipers, pads, etc the same, then I'm 100% with you), I don't disagree with you. After you start locking the tires rotors are only going to help dissipate heat, and past that point it's all up to the tires. My main point was that drilling and slotting does squat.

I was about to type up a big reply, but I realized I'd mostly just be paraphrasing information that's stated much better elsewhere:
http://www.mazda6tech.com/index.php?option=com_content&task=view&id=19&Itemid=50

The Lambo and Ferrari brakes, I honestly have no clue. Most of their higher-end cars use carbon brakes, which have a couple different rules, but I have no clue why Ferrari when with drilled rotors on the F355, F360, etc. Porsche doesn't actually drill their holes, they cast them into the rotor itself so they don't weaken it. You're right about them only saying it helps when it rains, though. They don't claim any performance benefit otherwise.

One question about your Corolla example: when you put in the Brembos how old were the rotors you replaced? I've seen a couple people use this argument, but then fail to mention that they replaced worn and warped OEM rotors. You really need to compare a set of fresh OEM rotors to a set of fresh drilled rotors and see if there's a difference.
