Designed for fast road, track, and bespoke motorsport builds, this advanced brake package has been successfully fitted to numerous classic Porsche 911 projects over the last decade.
Designed and manufactured in the UK, each caliper is precision-machined from aerospace-grade T6 billet aluminium alloy for exceptional strength, rigidity, and weight reduction.
The stainless steel pistons are specifically optimised for compatibility with the Porsche 911 master cylinder, while the internal fluid transfer design improves reliability and removes the need for external crossover pipework.
With front calipers weighing approximately 2.8kg and rear calipers around 2.2kg, this system significantly reduces unsprung weight compared to standard Porsche brake components. Combined with the larger 300mm front discs, the result is improved braking performance, sharper pedal feel, enhanced heat management, and greater confidence under demanding driving conditions.
This kit is designed to deliver modern braking capability while maintaining compatibility with classic Porsche 911 chassis and suspension configurations.
