Welcome to Wilhelm Raceworks

Since 2010, specializing in optimizing the MKII Toyota MR2 for road course, track day, and autocross use.  My goal is to improve the suspension, handling, and performance of the MR2 through measurement, analysis, and optimization, and to pass on these improvements to MR2 owners worldwide.  Please feel free to contact me with any questions about how I can help improve the performance of your MR2.
