Porsche’s 911 (997) GT3 and Turbo are platforms engineered specifically for high performance use, which also have unique brake demands. (Example: 450 horsepower for a 3.8 GT3 RS and 500 horsepower for a 4.0 GT3 RS)

The Brembo OE brakes equipped on the specific Porsche 997 GT3 & Turbo models are a sophisticated design for an OE application. The Porsche Brembo OE brakes utilize 6-piston aluminum fixed monobloc calipers front and 4-piston aluminum fixed monobloc calipers rear. The brake discs are heavy duty 380 x 34 mm ventilated front and 350 x 28 mm rear brake discs. While 997 GT3 and Turbo brakes physically look similar, their piston configuration and brake balance are tuned for the specific chassis. The GT3 places more of the brake balance towards the rear, while the Turbo is more demanding on the front brakes due to the AWD (All Wheel Drive) system and electronic aids.

The Porsche 911 GT3 OE brakes use a wide annulus (radial depth) front and rear for maximum pad swept area (this makes a significant difference in thermal capacity and pad life). The OE pads are also 18.5 mm thick front and rear which is comparable to most high performance aftermarket calipers.

There are certain limitations with the OE components on any high performance application as they are designed specifically for the car manufacturers to their requirements of comfort, wear rates in various road environments, cost, and serviceability.

As the braking system’s primary function is to dissipate heat, Brembo uses purpose-designed discs in order to increase the fade resistance and thermal capacity of the system. These Brembo Racing discs are directionally ventilated for enhanced cooling and slotted for better performance and continuously refreshing the pad surface. Brembo 2-piece discs are made up of a proprietary advanced cast-iron alloy which offers an exceptional coefficient of friction and resistance to thermal shock and fatigue.

The same Brembo Racing discs trusted every weekend in professional motorsports are also utilized in the Brembo Performance program (GT, GT|R, & Race Systems).

“At Olsen Motorsports we only use the best, most reliable components on the market. Brembo has come to the table with a complete package that has changed the way we think about brakes. With the many options in friction we are able to put together track specific brake packages to get the last bit of pace out of the many chassis’ s that we work with to stay consistent, competitive, and up front on track. The longevity and consistency of the product is amazing, and that coupled with the accessibility, knowledge, and support of the factory, Brembo is now the only brand that we offer to our customers”.

Tim Olsen, owner of Olsen Motorsports


“Ok, here‘s a factual event that happened to us, it was very eye opening to me at the time, I thought “this cannot be possible”, but it was because we did a back to back test later that morning and sure enough, it fixed the problem (this was at a Sebring test in February, the weather was mid 70’s to low 80’s).  The driver complained of poor threshold feel, we replaced the pads thinking they had lost their friction potential, still the same result. So then we changed rotors (thinking “this is insane but what the hell”), and on the second lap the driver called in saying “I can brake properly now”.  I learned a lot that day, to never be closed minded about things that otherwise seem obvious.

 Brembo rotors, combined with the correct pads, allow the driver to decelerate the car harder and more controllably because the materials are properly compatible – this is not case with other rotors and pads and we know this because we did back to back tests, the drivers response and the data proved it”

Craig Watkins, former Engineer of Flying Lizard Motorsports for 10+ years


“Although often overlooked, the ability to stop is really the most important aspect of sports car racing.  As a driver, I have been trusting Brembo products to slow me down for the majority of my career.  I am very demanding of the brake system on my race cars.  I need stability at the initial brake application, and the ability to modulate smoothly off the brake pedal is essential for optimizing corner speeds.  Having Brembo components installed on the car always gives me the confidence to push the limits throughout the brake zones.”

” In fact, it was Brembo products on the Brumos Racing Porsche that helped us make that final charge for the 2011 Rolex Series Championship.  A qualifying issue in the final race placed us at the back of the grid, and it wouldn’t have been possible to make our way up to the front without maximizing stopping capacity.”

Andrew Davis, 2011 Grand-Am Rolex GT champion with Brumos Racing.

How much does a Brembo Performance big brake system weigh vs. O.E. components

List below are a couple random systems that compare the approximate weights of a Brembo Performance GT system vs. the O.E. (Original Equipment) components from various makes and models.

In many cases a Brembo Performance system has a weight savings over OE brake systems even though the Brembo Performance system utilizes multi-piston calipers and often times larger diameter discs.

A Brembo Performance GT/GT-R big brake system is commonly comprised of:

Caliper

Either a 2-piece aluminum alloy, monoblock aluminum alloy, or
billet monobloc aluminum alloy caliper

Brake Pads

typically 2 to 4 pads per caliper

Rotor/Disc

1-piece rotor
– or –
2-piece disc with billet aluminum center and outer iron disc

Brake lines

typically 2-lines per axle set

Mounting brackets

typically 2 billet brackets

1st Comparison

‪‎Brembo‬ Performance GT 355mm
2-piece disc which is roughly 6% larger.
The GT 6-piston caliper is approximately 7.5lbs.

Compare that to the total weight of this Lamborghini rear system which is:
approx. 24.17 lbs total.
broken down by component:
it’s 15.94 lbs for the 14″ disc and
roughly 8.24 lbs for the forged monobloc racing caliper (w/pads).

Mike either has a strong finger or this Brembo CCM-R (carbon ceramic for street/track/racing) disc is nearly half the weight of iron.
