Brembo E9X M3 / E82 1M GT-R Big Brake Kit - 380x28mm 2-Piece Rear
The Brembo GT-R Big Brake Kit for the BMW E90/E92/E93 M3 and E82 1M is part of Brembo's GT|R range, pairing nickel-plated four-piston billet monobloc rear calipers with 380 × 28 mm two-piece brake discs. Positioned at the top of Brembo's GT range for street and track use, this complete rear-axle system is built for precise modulation, consistent pedal response, and effective heat management.
Billet Monobloc Caliper Design
Machined from billet aluminum, the calipers are formed as a single rigid monobloc structure and finished in durable nickel plating. A fixed, radial-mount four-piston layout with stainless steel piston inserts and recessed dust seals distributes pad pressure evenly while protecting the pistons from contamination, and a quick-release pad retainer simplifies pad service.
Two-Piece Ventilated Brake Discs
The 380 × 28 mm two-piece discs pair a high-carbon alloy friction ring with an internally ventilated, curved-vane design to manage heat during repeated braking. Floating D-bobbin mounting with anti-rattle springs allows the friction ring to expand independently of the disc bell, helping maintain consistent braking performance under demanding conditions.
Complete Rear Brake System
Supplied as a complete rear-axle upgrade, the kit includes calipers, pre-assembled brake discs, application-specific caliper adapters, stainless steel brake lines, brake pads, mounting hardware, and installation instructions. The calipers are finished in nickel plating, with drilled, Type 1 slotted, or Type 3 slotted discs available.
