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.

Spyder ABS Install

2003 MR2 Spyder ABS system installed in '91 MR2

The ABS system in the MKII MR2 is known to be a bit... let's just say it was the best they could do in 1990.  It wasn't great.  Better than nothing in certain circumstances, but overall not great.  Toyota did improve it quite substantially in 93, and I had retrofitted a 93 ABS ECU into my first MR2, but that only helped so much.  My "new" chassis didn't have ABS, but I kept all of the pieces from my original car so I could add it if I ever wanted.  But I just never could bring myself to install that ancient lump!  But what about something more modern?  Like the system from the MR2 Spyder?
