These kits are designed and tested specifically for car tuning enthusiasts and for who demands a prompt braking from their car. They offer superlative performance for both road use driving as well as for short track sessions.

The Brembo GT | M kits consist of one-piece or composite ventilated discs that can be either drilled or slotted; 4, 6 and 8 piston aluminium calipers; a complete set of high performance pads; metal-braided hoses and high quality hardware.

​This is a braking system made of motorsports-derived components that stands out for its high technology and performance. The kit consists of aluminium brake calipers with opposed pistons and one-piece or composite oversized discs that may be drilled or slotted. 

The Brembo GT | M kits are designed to combine the best solutions and therefore to properly respond to the peculiarities of each vehicle. The aluminum calipers are the kit's heart. Their monobloc version, i.e. machined from an aluminium piece that has been cast in Brembo's foundry, ensures an exceptional stiffness and a limited deformation. 

The discs that are provided in the kit have a unique ventilation system that improves the cooling capacity and increases by over 40% the resistance to the cracking that is caused by thermal shock. Additionally, the discs may be floating or one-piece, depending on the car model. The kit also includes a set of high performance pads, DOT approved metal-braided hoses, the adapter and high quality fastening hardware. ​

The radial-mounted fixed calipers and the oversized discs give the brakes more braking torque and greater thermal capacity. The result is more responsive, decisive braking that can be perceived even during normal road usage but that is also consistent on the simple sections of the track. 

The fixed calipers improve the system's durability and efficiency since the use of several opposed pistons allows an enhanced distribution of the pads' action as well as a more uniform wear on the friction surfaces. 

The outstanding rigidity of the calipers and the use of metal-braided hoses ensure that brake fluid absorption is reduced. This provides more responsive, stable pressure on the brake pedal thus improving pedal feeling and modulation. Finally, due to the aluminium alloy bell, the system with oversized floating disc reduces the unsprung weight (for improved handling) and thermal stress. The mounting system is engineered to permit a greater degree of both radial and axial float. 

This feature adds to the larger braking surface and allows better dissipation of the heat that is generated by the repeated, intense thermal stress that the discs have to withstand. This keeps the braking performance and pedal feel consistent even after several laps. 

The Gran Turismo kits’ painted calipers (available in red, black, silver, and yellow) that display Brembo's logo together with the slotted or drilled discs give an unmistakably sporty and eye-catching look to the car. This appeals to whoever wants to enhance their vehicle's design and stand out from the crowd. 

The GT | R kits are for the most demanding drivers. They are even higher performing and feature monobloc calipers that are machined from solid billet metal, slotted discs with diameters up to 405 mm and high performance pads. ​​

The counterfeiting of Brembo brake systems, as with many products made by the most iconic brands, is unfortunately something that is becoming more and more widespread. In this case, it is something that is potentially much more dangerous because it regards the performance of active safety systems which are vital to the safety of drivers, passengers and other road users. 

Brembo has always guaranteed the safety and reliability of its own parts and has developed an app called Brembo Check which can be used simply and quickly to certify that its products are genuine ones. 

With Brembo Check installed on your mobile device, all you have to do when you buy an UPGRADE product is use your smartphone to scan the unique QR Code on the label which can easily be seen on the purchased component or on the box, as in the SPORT range, to know if the Brembo product is original or not. 

To prevent tampering, the label is made using a printing and application procedure which prevents it from being removed; if you try to remove it, you damage the QR Code making it unusable. In this way, the label cannot be detached and cannot be affixed to any other products other than the original one. ​
