Established in 2007, and after learning his trade at many top motorsport preparation companies, Kevin Theaker began Rallysport Development (RSD) to produce world class motorsport vehicles and components.

Having always had a passion for rallying and especially the Ford Mk2 Escort, the business soon became focused on this marque and its various rally models.

With interest in historic rallying increasing, RSD highlighted the need to build period perfect cars for the sport employing traditional build and preparation techniques. With this in mind so began the dedicated and pain staking quest to gain knowledge and information from some of the periods most successful teams and engineers. During this process RSD have amassed a vast photographic and documented history of the works Ford Escorts and regard themselves as an authority on the subject.
