DECH Motorsports was founded in 1985 by Derek Hanson, seeking to provide an attainable high performance vehicle for racing enthusiasts, at an affordable price. Starting out with just a few dedicated customers, DECH set out to change the face of affordable high performance automobiles throughout Canada.
Utilizing a vast knowledge of suspension, DECH set out to analyze all the performance parameters of the car, and evaluate which modifications would best elicit the desired level of handling neccassary to out perform everything else on the street, and the track. Designing and testing numerous types of coil springs ( using spring rate test equipment not just seat of the pants testing ) and combing the damping attributes of Koni struts and shocks, the net result was a car that could lap the track with ease and still comfortably convey their owners to and from the course, without shattering vertebrae. These early DECH Mustangs were custom built to owner specifications, and came with a base horsepower rating of 240 HP.
