Rotors are a special alloy iron material that is heat-treated for uniform micro grain structure. This process and material are the key to the highest level of braking performance and wear characteristics.
Aluminum center hats are EDP coated for protection.
Convergent vane design
Patent Pending Open-Slot design combines slotted and vented rotor properties without the crack prone stresses involved with these 2 processes.
DACRO coated 10.9 fasteners on rotor ring to hat interface held in tension to allow floating under expansion loads
Forged 6061-T6 weighing only 4.5lbs
Direct Bolt-on fitment
7075-T6 Mount brackets are CNC machined and EDP coated
Low profile design for more wheel fitment options.
38mm internal seal piston is thermally vented to reduce heat transfer 90% over Aluminum pistons commonly used in BBK calipers. This means longer times at the track and less heat conduction into the brake fluid.*
Powdercoated finish in red, black and optionally blue
Uses Standard FMSI pads (D1149) making replacement pad options vast.
Tethered EPDM bleeder cap means no more lost bleeder caps.
Made in the USA , Designed fully assembled and 100% hydro tested prior to shipment in Fullerton,CA. Canada shipments are tax exempt due to NAFTA guidelines.
With all of these features these kits lead in performance and price.. Look at our other listings for complete package deals.
This is the heavier duty caliper suitable for extended track and competition use.
