BrakeTech AXIS Cobra™ SS Oversize Rotor Kit

BrakeTech AXIS Cobra™ SS (Stainless Steel) Rotors are extreme-performance, full-floating brake rotors designed for demanding enthusiasts and racers alike. Manufactured in the USA, the Cobra SS combines BrakeTech's AXIS™ floating system with its optimized Cobra™ petal design and proprietary stainless steel construction to deliver lightweight performance, durability, thermal capacity, and consistent braking performance.

The AXIS™ SS Oversized Rotor Kit delivers a twofold advantage. First, the larger diameter provides greater mechanical leverage on the wheel by moving the fulcrum point further out, so a given amount of pressure applied at the lever creates more stopping power at the wheel. Second, the larger rotor provides more mass, and greater mass increases the brakes' ability to deal with higher thermal loads. This is precisely the reason BrakeTech's 6mm rotors are a full 1mm thicker than the OE rotors.

At the core of the Cobra SS is BrakeTech's Direct-Link™ load-transfer architecture. Unlike conventional floating rotor designs, the Direct-Link™ system provides more than an 800% increase in load-transfer surface area, helping distribute braking forces more effectively throughout the rotor assembly. The result is a strong, stable floating design engineered to perform under demanding street, track-day, and racing conditions.

The Cobra SS features an optimized petal design engineered to provide the performance characteristics of a round rotor while avoiding the compromises commonly associated with exaggerated wave-style rotor designs. The proprietary heat-treated 400-series stainless steel rotor blade is also subjected to BrakeTech's Hi-Tech Cryogenic treatment to improve wear resistance and durability while maximizing performance with modern high-friction brake pad compounds.

This 6mm Cobra SS rotor configuration provides a lightweight, high-performance option for demanding street, track-day, and racing applications. Its reduced thickness helps minimize weight while retaining the strength and durability required for consistent braking performance.

Standard floater button color is black.
