The calipers in the kit are lightweight aluminium Super 8 pot 4 pad units. They are far more rigid than single or twin-piston OEM sliding caliper designs, resulting in less caliper flex and improved pedal feel. The calipers are designed around a pad profile that offers substantially more pad volume than most OEM pad profiles, resulting in improved pad wear life. This pad profile is manufactured by just about every high-performance and race pad manufacturer on the world market, making it easy for customers to source a wide variety of pad options in future.
