AP Racing will highlight some of its latest products, and celebrate its motorsport heritage, at the 2013 Autosport International show at the NEC, Birmingham in January.

New Radi-CAL™ GT Calipers
Developed from the AP Racing’s experience in F1, the three new designs feature stiffer dome-backed titanium pistons, which reduce machining complexity.

The CP6083 is a six-piston, swing-bridge design machined from solid aluminium alloy, for general GT & GT3 use, and allows quick pad changes. The caliper offers an 11 per cent weight saving compared to the CP6080 design on which it’s based.

The CP6165 is a six-piston, aluminium alloy monobloc calliper, produced for general GT/LMP applications, and is designed to operate with both carbon and iron discs. It benefits from nickel plating, reducing caliper temperatures, and offers a 5 per cent weight saving compared to CP6160 caliper.

The CP6169 is designed to operate primarily on carbon brake discs, with a carbon cooling duct as an available option. This slimmed, six-piston, lithium-aluminium alloy monobloc caliper is intended for general GT/LMP1 use, and benefits from nickel plating. It offers a weight saving of approximately 4.2kg compared to the CP6160 caliper.

700th F1 Clutch victory
For the last 40 years AP Racing has led the aggressive development of racing clutch technology and, at the 2012 Belgian Grand Prix the company celebrated its 700th victory for its clutch systems. The result ranks AP Racing as one of the world’s leading motorsport component suppliers.

The evolution of AP Racing’s clutches dates back to Jim Clark’s winning drive in a Lotus 49 at the 1967 Dutch Grand Prix – the first significant victory. The CP2125 fitted to this car had been developed specifically for the then new Ford Cosworth DFV engine, which also made its racing debut in Zandvoort, Holland that year. The following year AP Racing’s clutches achieved a clean sweep and helped Graham Hill to his World Championship in the Lotus 49B.

‘I’ Drive clutch
Conventional clutch designs typically feature external ‘jaws’ around the outer edges of the steel intermediate and main pressure plates, which can distort trapping the legs of the aluminium cover and cause the clutch to drag. The ‘I’ Drive design features drive tenons, which locate into internal jaws in the lightweight aluminium clutch cover, eradicating the onset of clutch drag.

CP5898 master cylinder
Developed to increase braking efficiency and enhance performance in racing applications, this new differential bore master cylinder is already in use in the Nascar Sprint Cup Series, and will be available to other categories including F1, sport cars, touring cars and rallying. Its advanced design improves braking consistency, by reducing unwanted low pressure pedal travel and operating at high pressure throughout brake actuation. It is also fully adjustable, allowing for a wide range of applications across different car set-ups and race series.

The principle relies on a relatively large bore taking up all the low-pressure, long travel within the system, including caliper piston retraction, knockback, trapped air compression and seal squash. At a set pressure a smaller bore cylinder is then switched into use for the higher-pressure, short-travel part of the braking event. Over the years, several designs have taken this approach but failed to win acceptance in racing circles, as they typically suffer poor pedal feel, aggressive brake bite and can prove difficult to modulate.

S-Vane disc
A new Sinusoidal Vane cast iron disc has been developed for NASCAR, with others due to follow in Touring Car, GT and Rally classes. Running between 70-100°C cooler than the old design, the new S Vane disc provides a significant improvement in brake performance, wear rate and reliability.

Armoured vehicle components
AP Racing’s range of products specifically designed and developed based on specific Armoured Car/Heavy Duty Vehicle testing procedures will also be in display at the NEC.

With the ability to engineer unique solutions for various Armoured or Defence applications, solutions can be tailored to a customer’s specific criteria and requirements. With careful consideration of the specific levels of armouring and weight increases, AP Racing can develop a brake system to effectively function in the environments and scenarios experienced by these vehicles.

We have a feature on AP Racing upcoming in the Jan/Feb 2013 issue of tkc mag…
