Product Details

The Brembo GT-S Front Big Brake Kit is a disc brake upgrade kit for drivers who want stronger stopping power, better pedal feel and more consistent braking than a stock system gives. The kit pairs high-performance monoblock or multi-piston calipers with larger slotted or drilled rotors, so it suits spirited street driving, track days and other performance use.

Key Features:

  • Rigid caliper construction: Brembo's one-piece or stiff multi-piston aluminum calipers resist flex under heavy braking, which helps keep pedal feel firm and consistent.
  • Larger rotors: Upsized, vented rotors absorb and shed more heat, which helps reduce brake fade during repeated hard stops.
  • Multi-piston clamping force: Pistons spread pressure evenly across the pad for strong, controllable braking.
  • Performance brake pads: Friction material is chosen for strong initial bite and stable performance across a wide temperature range.
  • Durable finish: The calipers carry a protective coating that resists heat, brake dust and road grime.
  • Racing heritage: Brembo supplies brakes to many top motorsport teams and performance car makers, and this experience goes into its aftermarket kits.

Brembo GT-S big brake kits are a bolt-on upgrade that can improve braking and the look of the wheel area. Choose the child variant for your application from the options on this page.
