If you can just replace the rotors, who can do that?

You are correct that you will only be replacing the outer disc when it's time for new rotors. The hat/bell portion of the disc should last the life of the vehicle as long as the rotors are replaced when needed and assembled properly.

Any Authorized Brembo dealer will be able to provide you with new discs and connecting hardware. These parts will come with detailed assembly instructions. The majority of our dealers are also trained to be able to handle the installation and assembly needed for any Brembo brake systems.

It's a relatively simple procedure if you are fairly handy. The only thing you will need to make sure you have handy is a properly calibrated "Inch-Pound Torque Wrench". The connecting hardware must be properly torque in order to provide the proper floating function.

Hey Gary, any info on when the E92 M3 BBKs are coming out?
I'm guessing in a few weeks?

For a Z8 we did a bit of a hybrid kit. For calipers, we used the Brembo GTR but with dry breaks instead of bleed screws (if you look carefully, you can see one in the pictures) as, though requiring far more maintenance, the dry breaks are better at preventing weeping (as F1 discovered several years ago, which is why, when cost is not an issue, the change is made). For hats (bells), we made our own from a high temperature aluminum used in F1 and not found in any of the standard kits. For rotors (disks), we used ones that are lighter weight than those in the Brembo kits (we saved 2.5 lbs. per front and 2 lbs per rear) and had them drilled in addition to being slotted (Brembo can do this too). For brackets, we made our own to reduce weight (one should not try this unless one has the engineering resources to determine what metal can be eliminated while maintaining strength). Finally, for lines we made our own with titanium fittings and covered them in DR25 to prevent having raw metal lines which, through movement and vibration, could act as saws on parts around them. Also, as to the brake line fittings, certain BMWs (and other vehicles) have particularly shaped fittings going into brackets on the chassis side (also seen on the pictures) and no kit that I have seen has these fittings -- and without the these fittings one might have less than optimum line mounting. Finally, as to AP, which, of course, is owned by Brembo, they, too, have excellent kits and excellent street and race calipers (Brembo and AP split, almost equally, the F1 grid and, in sports car racing, they have a substantial part of the field).

Brembo for MK5 GTI

Open the link...
Click on the " >Detail " tab, next to the "Assembled Disc"icon.

The difference in price comes from the differences in the rotors.

As you can see, the VW kit uses a 2pc. full floating disc.
The Mazda kit uses a 1pc. cast disc.

When we have a 1pc. disc available, or can produce the quantities necessary to create one, the 1pc. cast disc option will always be less expensive.

With the 2pc. discs you are starting with a very high quality outer disc that comes directly from our Racing Division.

The race version disc is bolted to a vehicle specific billet aluminum hat/bell.
The hardware used to connect the two components is our patented "McLaren" hardware.
That provides the full floating ability while minimizing the chances for noise that is associated with a floating disc assembly.

The two piece discs offer additional benefits such as weight savings, preventing warpage, full floating action, increased longevity, and are much more expensive to manufacture. If you look at any of the vehicles where we do offer the options in both 1pc. or 2pc. rotors you will see an approximate price difference of $1000-$1200 dollars.
Hi Gary, I am interested in the Brembo GT for MK5 GTI but do not want to change my 18" OEM Denver Wheels. Can the calipers clear base on your experience or spacers are required ? Appreciate your feedback.

I've pulled in late in this discussionbut wanted to say a couple things.

GewoW, what would make you say that the Brembo brakes would not last? As said here, the old saying you get what you pay for is totally valid here.
I would go with Brembo or AP Racing as my choices.
In IMSA racing (endurance races) we used AP Racing with fantastic success especially noted in 12 and 24 hr. races.
For high performance street car applications and club events for me it's Brembo all the way. There's never been a complaint with Brembo's.
The applications are spot on and perfectly matched. To debunk another post here, I say BS if you think Brembo doesn't do its R&D. Presently I have a set on my E60 M5 with 16" front rotors.

Brembo all the way.

Sorry but I gotta throw another one in there: Performance Friction! My friends who race BMWs swear by them, also a number of guys who race their GT3s. One of the guys also runs them on his street M3.
Are you looking to race or just want some bling? The stock brakes are pretty good and honestly on the street or occasional DEs you aren't going to need or be able to use much more than stock. If doing DE's you can just upgrade the pad.

Robert, thats a nice setup you guys made! Can you PM more information about it?

GewoW - the E92 kit is available already.

Juan - I agree, Brembo does more research than any other company, which explains why their kits always fit PERFECT and are top notch. If they werent that good, why would Ferrari and Lambo use them?

kc911 I agree with you about the brake pad change as an effective result for DE days. In my experience the stock brakes in the M5 when put to the test on a road course do not hold up. They punk-out and go soft. You need to at least do a performance pad change. For the average driver the brakes are fine but not if you consistently go deep lap after lap.

Cheers, GT3Ranger

+2 for ap racing it is from my experience under the few cars ive driven with the 2 that Stoptech has much better quality and stopping power

I've seen quite a few GTR setups but that one is just... WOW.

amazing setup Robert.

[quote=M5Kid;1751736]Not sure if this is still an issue, but in the past it was common knowledge that Brembo didn't do the proper R&D (or didn't care) to give the proper balance in braking to customers who bought their front only kit. The pistons were oversized, creating an undesirable front brake bias that actually resulted in increased stopping distances.


Can you really hold it against Brembo if someone doesn't upgrade their whole braking system. I had the full 996TT kit on my '99 996 and it was awesome. Now that I have an '02 I'm lookng again. I'd consider others, but with your life on the line at the track, you can't go wrong with Brembo. A Brembo 996TT Kit with AP or Castrol Fluid (changed often) and a great set of pads is all you could want. Talk to racers in your area. See what they use.
