Disc size : 380 x 34 mm
Direct replacement for steel assemblies with 380mm front discs
Hat and Floating disc assembly kit with slotted road brake discs (Left and Right)
Two-piece floating slotted front iron disc upgrade (including centre lock wheels)
- Rotors come with 72 cooling vanes for optimal cooling.
- Assemblies made of CM-250 formulated high carbon alloy cast iron, it allows for high-temperature strength and durability.
- Hat assemblies are CNC machined from 7075 T6 material then hard anodised.
- Rotor rings are heat treated to release stress in the rotor to avoid deformation and vibration.
9m fast road/track brake pads feature very good modulation and release characteristics. They have a low metallic resin bonded material containing steel and aramid fibers so the friction level of the material maintains constant at a low-medium level.
High brake coefficient of friction 0.55
With higher stopping power and maximum effective operating temperature, the 9M compound is ideal for advanced high speed track events, competitions and heavier cars that require maximum braking performance.
- Good modulation and release characteristics
- Excellent pad and rotor life
- High fade resistance compound, with solid pedal feel throughout the effective temperature range
