The 12 piston caliper is the current top of the wortec range and is designed for very high performance cars and large SUV type vehicles where maximum retardation is required.
Due to the size of the caliper and the requirement for a centre bridge to maintain rigidity and performance, the caliper uses 4 pads per caliper. This configuration provides a pad area equivalent to two! 6 piston calipers.
The advantage of using 4 pads is that the pistons can be positioned and sized to provide maximum effect on the individual pads. The sizing improves the pedal feel and gives the drive confidence to uses the system to best effect.
The 12 piston caliper is very effective at dispersing heat and has the "WHiSPeR" machining included in the design. This ability to shed heat means that not only high performance cars benefit from this system, it also is used to very great effect on SUV and Mini vans where the 12 piston system can cope with the extra weight of the vehicle.
Some application that have benefited from the 12 piston caliper are "Armoured personal protection cars" and "Luxury limousine vehicles" where the customers safety is paramount.
For performance car applications the calipers can be supplied with race pistons which have been lightened and are installed without dust seals so they cope with the extreme heat of race application. The caliper like all the other calipers in the wortec range can be retro fitted with race pistons and changed as and when required.
A major consideration for performance applications is weight and this is an area where the 12 piston system wins over other large brake kits as it is very light compared to its size and is more than often lighter than the much smaller OEM system the car came with!
This system is designed to use our 388mm and 410mm rotor sizes and as such requires a 20" minimum wheel size, but in some cases if wortec wheels are used the wheel size can be reduced to 19" as the forged wheel has more clearance inside.
