Compbrake are the UK distributor of Powervane racing rotors and big brake kits which offer the ultimate in performance braking, these may also be called Big Brakes. Curved vane in design and are the leaders in racing rotors when used with race callipers. Performance rotors need to with stand the demands of motorsport with out fade, when used with circuit suspension. Brake fade is virtually eliminated with Powervane racing rotors. Race callipers and performance rotor work together under heavy braking with circuit suspension to produce outstanding performance, installed with the correct friction material and circuit suspension makes this combination a number one winning choice for performance brakes with race callipers and performance brake discs. Racing rotors have to be perfectly balanced and to with stand the heat that is demanded for motorsport braking. Performance rotors like powervane which are used in all our big brake kits can with stand the heat without cracking or warping unlike many offered on the market today. Racing rotors which are used with aluminium bells or known as tophats keep the weight to a minimum a major requirement for racing discs for unsprung weight compared with a one piece heavy brake disc sometimes found with circuit suspension.             Performance Brakes and Big Brakes Powervane performance rotors and made from special castings purposed designed for motorsport braking and racing brake kits and racing brakes, using the most modern foundry and engineering facility's were quality procedures are in place. Each racing rotor or performance brake disc is precision machined to the lowest tolerance run out a definite requirement for performance brakes in competition. For good race callipers to work and produce good results good racing rotors are also important to achieve shorter stopping distances, with race callipers. Not all racing rotors or so called performance rotors offer this quality design for big brakes that Powervane curved vane racing rotors offer In motorsport braking were de- acceleration is needed fast and continually working those pistons in the race callipers all Powervane racing rotors are 6 gas vented (grooved) that offer a no noise design performance brake disc supplied with all our racing brake kits and performance brakes Racing brake kits Compbrake offer a complete design service for brake kits, performance brakes and big brakes , with performance brake discs in house here in the UK and offer a comprehensive range of brake kits on the shelf along with racing callipers for fitting to circuit suspension and standard stub axles for same day world wide shipping. Performance brake discs Compbrake are the UK main distributor of brake rotors and Performance brake discs with a range from 247mm to 360mm diameter and 11mm to 32mm thick straight and curved vaned by Powervane for the ultimate in performance brake disc and brake rotor.
