Product Details

The Brembo GT-S 1M3.9033AS front big brake kit delivers professional-grade stopping power for enthusiasts who demand race-inspired performance on both street and track. This complete braking system features motorsport-derived components engineered to provide exceptional thermal management and consistent performance during aggressive driving.

Key Features:

  • 6-piston monoblock aluminum calipers with hard anodized black finish for superior thermal resistance and corrosion protection
  • 380x32mm two-piece floating Type 3 slotted rotors with cast iron discs and precision-milled aluminum hats for reduced unsprung weight
  • Type 3 curved slot design continuously refreshes brake pad surface, removing debris and maintaining stable friction coefficient
  • Racing-style ventilated pistons with dual inner seals (pressure seal and wiper seal) for optimal performance and durability
  • High-performance brake pads with application-specific friction materials optimized for maximum grip
  • Stainless steel braided brake lines for improved pedal response and feel
  • Complete mounting hardware and caliper brackets for vehicle-specific precision fitment

The M6 monoblock caliper construction provides exceptional rigidity and resistance to deformation even under extreme temperatures, ensuring consistent pedal feel during extended track sessions. The enhanced cooling capacity of the two-piece rotor design increases resistance to thermal shock by over 40% compared to stock systems, delivering reliable braking performance when you need it most.
