Brembo 1N2.9503AS GT-S Front Brake Kit 405x34mm 2-Piece Slotted Rotors

The Brembo 1N2.9503AS GT-S brake system represents a significant performance upgrade for Mercedes-Benz W221 chassis vehicles. This complete front brake kit features massive 405x34mm two-piece slotted brake discs paired with Brembo's hard anodized aluminum calipers for exceptional stopping power and thermal management.

Key Features:

• 405mm x 34mm two-piece slotted brake rotors with floating design for reduced weight and improved heat dissipation
• Six-piston monobloc calipers (M6 caliper type) with hard anodized black finish for corrosion resistance
• Type 1 (TY1) configuration optimized for front axle applications
• Slotted rotor design helps evacuate brake dust and gases while maintaining pad bite
• Complete bolt-on kit includes calipers, rotors, high-performance brake pads, and stainless steel braided brake lines
• Direct replacement for Mercedes-Benz S-Class W221 models (2006-2013) including S350 and S550

Brembo GT-S systems deliver race-proven braking technology for street and track use. The hard anodized caliper finish provides a distinctive black appearance while protecting against the elements. Two-piece floating rotor design reduces unsprung weight compared to one-piece rotors while allowing for superior thermal expansion characteristics. This system dramatically improves brake pedal feel, fade resistance, and overall stopping performance over factory brakes.
