With over four decades spent in the racing industry, primarily focused on building Wissota and IMCA modifieds, I have decided it is time to retire from building customer chassis starting in 2026. I will continue to provide service and support for existing JMR customers.
Throughout my career, I have had the privilege of working with many exceptionally talented drivers and teams, and I am deeply appreciative of those opportunities.
Best Always,
Jay McDonald
