Product Description

Cosworth Sport brake kit’s feature fully forged calipers for optimal strength and light weight. The bolt in bridge design allows for a super stiff caliper without sacrificing cooling. The end result is better performance with less vibration, noise, and pad taper.

Cosworth 2-piece rotors are designed for 10-30% better airflow than directional vaned racing rotors. They were produced with a proprietary cast iron formula, which was specified with durability in mind. The hats and brackets are made with a special type of billet aerospace aluminum and are CNC machined in the USA to ISO standards.

All parts are bench tested prior to shipment. Each caliper is 100% pressure tested to 2,500 PSI. Every brake line is 100% pressure tested to 4,500 PSI. Every assembled two-piece rotor is tested for runout. Each kit is optimized for specific vehicle application.
