12/3 Calipers - as fitted to  the rear of the Aston Martin DB5/6 and can be supplied with or without handbrake linkages.

Although these calipers were originally designed for road use we do recognise that the cars are often raced so we can offer these calipers with high temperature seals and without dirt seals which is more suitable for racing.
