DG Spec is a line of parts endorsed by National Champion Scion road racer, Dan Gardner. Gardner draws up the specifications for the parts himself, and the parts have been track tested and proven. The goal of DG Spec is to provide car enthusiasts with a lineup of parts that were developed on the track and that have significant performance advantages. Parts are offered either in identical trim to what Gardner and his team race with, or a milder variation for the street, but still based around the performance standards specified by Gardner himself.
