The MRT Track Day Mustang
American Muscle takes form of a Ford Mustang in many enthusiasts’ minds. Historically Mustang has represented a care free spirit embodied in performance and style. Though this legacy has been kept in tact through the current production Mustang, a few tricks have become available from a few Companies such as MRT (Mustang Racing Technologies). Building a Mustang that is ready for the European high performance driving scene requires a keen understanding of the vehicle systems and how they interact during extreme conditions. The MRT Track Day Mustang embodies a collection of refinements that makes this car an exhilarating vehicle that will provide a ton of reliable fun at the track. Here is how we prepared this car
Engine: Custom built by MRT, this Aluminum block 4.6L 4 valve engine puts 350 foot pounds of torque to the tires. Forged internals such as crank shaft, Connecting rods and pistons allow us to build maximum power while keeping the weight down due to the aluminum block construction versus cast iron (found in most Mustangs produced). Induction and exhaust are critical for allowing the engine to breath easy and producing maximum power. MRT uses their own Cold Air Induction system, mated to a larger mass air meter to resolve any induction losses. As for the exhaust, MRT uses the JBA mid length header along with the MRT High flow H-Pipe and cat-back exhaust…all constructed from stainless steel. Finally, we head to the chassis-dyno to calibrate this car for optimum performance.
Chassis: The key to having fun on the track is having a suspension and brake system that inspire confidence. MRT uses the Mustangs base architecture as a starting point and refines it so it can perform with predictable confidence on track. To accomplish this, MRT replaces all rubber bushing with high performance urethane bushings, adjusts the front control arms forward in vehicle lowers the car with high performance springs, struts and shocks, adjusts the steering geometry with extended ball joints and adjustments to the steering rack. Caster and camber can be set to aggressive setting through the addition of a caster/camber plate. The body structure is made more ridged by adding a strut tower brace under the hood and welding in an extreme matrix sub frame connector under the car. The rear suspension is a Cobra Independent Rear Suspension upgraded with urethane bushings, frame reinforcements and a differential girdle. Cobra Brakes provide plenty of clamp force to slow this pony down for the corners, Anti-loc brakes are kept in tact to ensure maximum control is maintained.
