Why upgrade to Brembo GT-BM
- Greater thermal capacity: 380mm 2-piece floating rotor dissipates heat faster than OEM discs, delivering fade-free performance under sustained heavy braking.
- Stiffer, more linear pedal feel: 4-piston monobloc construction eliminates caliper flex, giving you the same pedal response on lap 1 and lap 20.
- Lower unsprung weight: 2-piece floating assembly reduces rotational mass by up to 22% per wheel vs stock single-piece OEM rotors.
- Italian OEM quality: Built on the same production line that supplies Porsche, Ferrari, and AMG performance models from the factory.
- 3 caliper colours: Match your wheel and interior accents with Black, Red, Yellow.
