Why upgrade to Brembo GT-M
- Greater thermal capacity: 345mm 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.
- 4 caliper colours: Match your wheel and interior accents with Black, Red, Silver, Yellow.

- What's the difference between GT-M, GT-S, GT-R?
- All three use the same physical caliper body; they differ in internal piston size, pad compound, and rotor pattern. GT-M is the street-oriented base tier, while GT-S and GT-R add progressively more aggressive track capability.
- Are brake pads included?
- Yes — one set of Brembo street-performance brake pads is included. Optional upgrades to Pagid, Ferodo, or Schaffen compounds are available.
- What brake fluid does Brembo recommend?
- DOT 4 meeting Brembo's specification (minimum dry boiling point 260°C). We recommend Motul RBF600 for street and RBF660 for track use.
- Do I need wheel spacers?
- No — all Brembo GT-M kits are designed to fit within OEM wheel offset and caliper clearance specifications for this fitment. A minimum 17″ wheel is required.
