On pre 1974 cars, with steel rear arms, the later alloy arms will need to be fitted (not 930 turbo arms) as these calipers are not suitable for use with the turbo/930 rear arms

Kit Contents
• 2 x 6-piston billet front calipers with mounting brackets
• 2 x 4-piston billet rear calipers
• 2 x 3.2 front brake discs
• 2 x 3.2 rear brake discs
• 1 x Ferodo DS3000 front brake pad set
• 1 x Ferodo DS3000 rear brake pad set
• 2 x braided front brake hoses
• 2 x braided rear brake hoses

Featuring lightweight 6-piston front calipers and 4-piston rear calipers, this complete brake package has been successfully fitted to numerous bespoke Porsche road and race builds over the last decade.

Designed and manufactured in the UK, each caliper is precision-machined from aerospace-grade T6 billet aluminium alloy, delivering exceptional strength, rigidity, and weight reduction compared to standard Porsche brake calipers.

The stainless steel pistons are specifically optimised for compatibility with the Porsche 911 master cylinder, while the internal fluid transfer design improves reliability and reduces 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, improving braking response, steering feel, suspension performance, and overall vehicle dynamics.

Designed to work with standard brake discs and fit beneath 15-inch Fuchs wheels, this kit offers an ideal combination of classic fitment compatibility and modern braking performance.
