Ford Fiesta ST Rally Car Specs - Updated May 2026

This car will be used to compete in the ARA Limited 2WD class. This is a mostly-stock class. At the time of writing, the Fiesta is not ready for stage rally, but is slowly being prepped for it. In the meantime, I am competing in the SCCA Rallycross Modified Front Wheel Drive (MF) class.
