Originally from Rochester, New York, James Walker, Jr. is a licensed Professional Engineer at Carr Engineering, Inc. He currently resides in The Woodlands, Texas, and brings 30 years of real-world experience to his analyses of vehicle dynamics and the reconstruction of motor vehicle crashes.

James graduated from the GMI Engineering and Management Institute in 1994 with a degree in automotive mechanical engineering. Following his passion for auto racing, he founded scR motorsports in 1997. He competed for seven successful years in the Sports Car Club of America’s SSC and ITA categories. Despite shifting his on-track focus to high-performance driving instruction with the Porsche Club of America in 2004 due to his growing family, he still found time for the occasional ChumpCar race, often behind the wheel of a Saturn SC2. In 2017, he joined the team at Risi Competizione, competing for two years in the North American Ferrari Challenge 458 Championship. He continued with Risi into the popular TCR category in 2019, pursuing the TC America Championship in an Alfa Romeo Giulietta.

The 2020 and 2021 seasons presented new challenges, as James partnered for the first time with BimmerWorld Racing and Bill Auberlen to pursue the GT4 SprintX Pro-Am Championship. In 2022, for his third attempt at the championship, James was paired with Devin Jones. The 2023 season brought further change, with James sharing a brand-new second-generation BMW M4 GT4 racecar with co-driver Tyler McQuarrie. In his most successful season to date, the duo scored a second-place finish in the GT4 America Pro-Am category, narrowly missing the championship by a single point.

Parallel to the evolution of scR motorsports, James has actively served as an industry advisor to Kettering University in the fields of brake system design, vehicle dynamics, and brake control systems. He has been a brake control system consultant for StopTech, authored High-Performance Brake Systems: Design, Selection, and Installation, and serves as an SAE Master Instructor in his spare time.
