'I' Drive Technology:
AP Racing has developed a new design of clutch. Whilst 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.The ‘I’ Drive design has been proven via a program of extensive dyno tests which assessed durability in challenging conditions. During the test the ‘I’ Drive clutch maintained optimum performance under arduous operating conditions for significantly longer than the conventional clutch design. There research shows the new clutch design to be five times more durable when subjected to the same test parameters.
With up to 10% less mass than conventional clutches, and with 15% less rotational momentum, ‘I’ Drive design also features an innovative ‘wear plate’, to combat wear on the drive legs of the lightweight aluminium clutch cover, where they interact with the steel plates. This problem, common to all sintered clutches with aluminium covers, is reduced by the use of thick wear ‘pads’ held captive on the drive faces of each of the aluminium cover drive-legs, which provide robust wear surfaces.
