Brembo 1ND.9504AS GT-S Front Big Brake Kit Hard Anodized - 6-Piston 405x34mm

The Brembo 1ND.9504AS GT-S Series Front Big Brake Kit is a complete, track-capable braking upgrade engineered for performance street and dedicated track day use. Part of Brembo's GT-S (Sport) line, this kit bridges the gap between road and race, featuring hard anodized aluminum calipers derived directly from Brembo's motorsport and OEM racing programs.

GT-S Caliper Technology:

• Hard anodized aluminum caliper body for superior surface durability, corrosion resistance, and sustained performance at elevated temperatures
• Racing-inspired piston design with stainless steel piston inserts and twin internal seal design — including an inner pressure seal and recessed outer dust boot — for long-lasting track use
• Radial-mounted fixed caliper with opposed pistons for even brake force distribution, maximized rigidity, and uniform pad wear
• Brembo logo engraved in racing-style red finish

Oversized 405x34mm Two-Piece Rotor:

• Large-diameter 405mm iron disc provides significantly increased swept area and thermal mass compared to factory rotors
• Two-piece floating design with aluminum hat reduces unsprung weight and minimizes thermal stress transferred to the hub
• Exclusive internal venting system improves cooling capacity and increases resistance to thermal shock cracking by over 40%
• Available in cross-drilled or slotted configurations to match driving style and usage

Complete Kit Contents:
