This Strap Drive System has been developed by AP Racing both for Road and Race applications. The standard fitment brakeĀ discs on many performance cars can suffer from brake vibrations caused by disc distortion. This generally occurs on fast road and track installations.

On many performance cars the typical standard brake disc will be a heavy duty ventilated single piece casting. Couple this type of rigid disc to a standard hub and wheel bearing and the result is any hub distortion / run out will transfer onto the disc brake faces. This eventually results in brake vibrations, usually picked up through the steering wheel.

The AP RacingĀ Strap Drive System offers a new take on the floating systems already in the market place. Strap Drive uses a series of stainless steel straps to locate the disc to the mounting bell, producing a flexible coupling between the hub and the disc faces. This allows the disc to run true in the caliper under all conditions and also permits the disc to expand and contract without being restricted.
