Is the track your environment, and are track days your routine? The Brembo GT-S Big Brake Kit from Accesspeed is the natural evolution toward racing. The Brembo GT | S (“Sport”) series is the perfect bridge between road and track. With 4 or 6 piston calipers directly inspired by racing applications, it’s a decisive step toward high-level performance. These calipers feature race-style ventilated pistons, recessed dust seals, and hard anodizing, making them capable of withstanding the most extreme thermal and mechanical stresses. Brembo GT-S is the ideal choice if you regularly hit the track and need a braking system that delivers consistent, reliable performance—even during the most demanding track days. For Brembo, GT stands for Gran Turismo: a complete line of braking systems designed for track-day enthusiasts and for those, like you, who demand more from an aftermarket brake system. More responsiveness, more sportiness, more heat resistance, even in the most extreme conditions. Each Brembo GT-S Series Big Brake Kit from Accesspeed includes:

• Cast monobloc aluminum calipers with radial mounting and opposed pistons for a more even brake force distribution, greater stiffness, and uniform pad wear.
• Upsized discs: one-piece, two-piece or composite, fixed or floating, with dedicated slotted or drilled patterns, specifically engineered for each car model. The most popular solution features Type 3 (TY3 or T3) slotted discs: this finish continuously refreshes the pad surface, removing debris and impurities, and ensuring a stable friction coefficient. The result is consistent, precise, and reliable braking - even in the most demanding conditions.
• Most discs feature an exclusive ventilation system that optimizes cooling and increases resistance to thermal shock, ensuring greater safety and extended durability.
• High-performance brake pads, optimized to deliver maximum grip in any condition.
• Braided stainless steel hoses for most applications.
• Aerospace-quality adapters and mounting hardware for precise, secure installation with no compromises.

GT | A, M, BM, S, R

Each letter identifies a different kit, and the name comes directly from the type of caliper used. These aren't just codes: they’re carefully designed choices tailored to specific driving styles. The result of these features is a braking system that looks the part, feels the part, and truly makes a difference. Brembo GT Big Brake Kits from Accesspeed are a top-shelf solution for braking performance.
