What’s included in this Brembo GT-M kit

• 2× 2-piece floating rotors 345x28mm (LH + RH)

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.

Frequently asked questions

Will this Brembo kit fit my 2015–2016 PORSCHE 981.1 BOXSTER GTS (PCCB EQUIPPED)?

Yes — this 4-piston GT-M front kit is engineered specifically for the 2015–2016 PORSCHE 981.1 BOXSTER GTS (PCCB EQUIPPED) rear axle at OEM ride height. If your car is lowered more than 25mm or has non-standard wheels under 17″, contact us first.

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.
