Mark Rushbrook prepares and drives the black #21 ITA Saturn.  Born and raised in the Laurel Mountains of Pennsylvania, Mark learned to drive on country backroads full of twists, turns, and blind apexes.  Driving was never only a means of getting from point A to point B, but was instead a challenge of finding the best line in every corner. 

After completing his Bachelor’s degree in Mechanical Engineering at Penn State, Mark moved to Michigan to earn his Master’s Degree in Mechanical Engineering, and to start working full-time in the automotive industry.  Mark applies his 10+ years of chassis and vehicle dynamics experiences on the race track, as well as developing new products for SPS.

Shortly after arriving in Michigan, Mark was introduced to SCCA Solo II Autocross Racing.  He successfully campaigned his 1990 Pontiac Grand Am H.O. Quad 4 (on street tires!) and his 1995 Saturn SC2 for several years, including strong finishes at Nationals in 1995 and 1996.
