​The Brembo GT-R braking systems for the Challenger RT are designed to meet the needs of aggressive braking whether on the road or the track. Brembo Challenger GT-R Big Brakes are the most advanced expression of all Brembo's experience in braking system design. The GT-R Challenger RT Big Brake Kit is comprised of single block billet aluminium calipers with 4 and 6 piston radial attachment, two piece floating discs, pads with different friction material and high performance hardware.

The GT-R calipers are made from billet aluminium with radial 4 and 6 piston attachments. They reduce the non suspended weight, improving the dynamics and vehicle performance. They are designed to provide a constant locking strength and the sensation of a stable and reliable pedal. The pistons with stainless steel radiators allow a significant reduction of heat passage during extreme driving, reducing brake wear to a minimum. In order to guarantee protection against corrosion and to provide high quality in the field, the GT-R calipers are nickel plated and have the Brembo logo CNC machined in red embossing.

The GT-R system has been designed for the driver who demands exceptional performance on the street and on the track. It includes 4 or 6-piston monobloc calipers, two-piece floating brake rotors, a selection of friction materials and all the necessary hardware to insure seamless installation.

• The GT-R calipers are machined entirely from billet like a $10,000 race caliper, not cast like our GT calipers.
• Billet calipers include the benefits of a full race brake system: more stiffness, lighter weight (GT-R calipers achieve a weight reduction up to 10 percent compared to casted versions) and more thermo-mechanical resistance.
• The nickel-plated finish provides additional treatment against corrosion and ensures a long lasting, attractive look.
• The pistons, complete with stainless steel inserts, provide an additional heat barrier virtually eliminating fade even during max-limit and on-track driving.
• Unique dual inner seals design keeps the seals away from excess heat. The inner seal acts as a pressure seal, with the outer seal acting as a wiper for long seal life in extreme conditions.
• The calipers provide less brake fluid absorption and a stiffer pedal feel delivering consistent clamping force suited for drivers wanting to make the most of every second.

GT-R braking systems include two piece floating discs which reduce the suspended weight and dissipate heat quickly. The floating disc's anti-noise hardware is the direct result of Brembo's experience with brakes designed for Formula 1 competition.
