TORA Spec Cup Season 5: The Car

Post by CRA XenoMorph on Fri 19 May 2017 - 13:39

2012 BAC Mono









Above all else the BAC Mono has been designed to optimise the driving position – in the middle, central to the wheels, and the balance of the car.

The BAC Mono is constructed using high-strength carbon fibre composite around a steel safety cell. The cell is designed to offer maximum safety featuring a FIA compliant steel rollover structure, a sophisticated side impact structure and a front carbon crashbox.

Powering the BAC Mono is a longitudinally mounted 2.5 litre, 305 bhp four-cylinder power plant provided by Mountune. Coupled to that engine is an F-3 spec 6-speed sequential gearbox from Hewland.

Suspension is a fully-adjustable pushrod suspension with damping elements made by SACHS Racing. Fitted with 295mm ventilated discs, AP Racing brakes provide stopping power.

Tyre manufacturer Kumho has used their vast experience in motorsport and road cars to develop a special rubber compound for the Mono, which is designed to work with the low weight and optimized pushrod suspension.

The BAC Mono’s central driving position makes the driver an integral component of the car, creating an unparalleled synergy between man and machine. With this in mind, each customer is fitted for his or her seat, pedal reach and preferred driving position.
