APR Motorsport, one of the most experienced tuners in the Volkswagen world, puts a lot of research into developing its products that find their way onto your VW in the driveway. Like any self-respecting car manufacturer's Research and Development department, APR finds that the best way to get that experience in a short amount of time is through most automotive enthusiast's favorite weekend hobby, motorsports.
A company can't continue its development of new products, however, if they stay complacent and stick to one setup event after event. There is one major difficulty that comes with always forging ahead and changing things, especially in the motorsport world, and that is uncertainty. Changing settings and components affords lots of research in what changes do what to a car, but it can also cause the car to act in a way that's unexpected and hindering, and ultimately get between you and a podium, or a points lead.
