The car benefits from a multipoint rollcage, designed to be HANS compatible as required from January 2007. The design complies with Appendix J of the FIA International Regulations. It includes 3 x “X” brace in the rear of the car including above the passengers heads and “twin tube” door bars with no cross-over.
Underbody Protection:
A substantial 6mm aluminium sumpguard to protect the engine and transmission components, manufactured to an M-Sport design, has been added. The standard fuel tank has a Kevlar composite moulded guard to protect from stone damage, plus the exhaust tunnel and fuel tank have both been protected with heat-proof lining. The fuel filler neck also has a kevlar composite moulded guard to protect this area. Optional underfloor and side-sill guards have also been added.
Interior:
The majority of the trim as authorised under Gp.N has been removed from the car to reduce the weight and allow the fitment of the safety features required in a rally car designed to compete in any region. The seats have been replaced with Recaro competition versions made from composite materials. To these have been added Sabelt 6pt harnesses, a Sabelt suede steering wheel plus an integrated fire extinguisher system with electronic control
Engine:
The basic engine remains standard with only additions being a revised “foam” air filter and a stainless steel exhaust system including a motorsport specification catalytic converter. The engine ECU has been modified to revise the fuel and air ratio and optimise the ignition. Modifications have been made to the “pedal map” for the electronic “fly-by-wire” throttle which improves throttle response and engine torque in the lower gears.
Transmission:
The car has a 5-speed “dog” engagement gearkit fitted to a standard ST150 casing. The gearbox design and ratios have been developed in conjunction with SADEV. Standard uprated driveshafts are retained. A “piggy-back” wiring loom has been developed to supplement the standard car wiring loom, incorporating the additional electrical requirements of the rally version. This includes an electronic circuit breaker to cut power to the electrical circuits in the event of an accident. It also includes the wiring for additional electrical requirements like map light, spotlamps, radio, tripmeter etc etc. The standard ST150 front and rear disc brakes are retained. The pipes in the braking system are replaced by braided steel hoses and an adjustable pressure-reducing valve is fitted to the system while still retaining the dual circuit diagonal braking required to comply with Gp.N regulations. Brake pad compound have been revised. Using the uprated suspension of the standard ST150 as a basis, which includes revised front suspension knuckles for additional negative camber and a strengthened twist beam rear axle, M-Sport engineers have added Reiger dampers which are adjustable for rebound and revised spring rates to improve the ride over rough surfaces found on stages. In addition the steering rack on the standard ST150 has a quicker ratio than the standard Fiesta to give improved turn-in.
