These are evenings the track is open to anyone and everyone to race down The Fastest Track in Michigan! It doesn’t matter if you are driving a fast racecar or “mom’s grocery getter”, anyone can drive down the racetrack. These events are offered on specific Wednesdays and Fridays.  The open Test & Tune evenings on Wednesdays and Fridays are a fun way to test and tune your vehicle or race against others if you choose.  These are throughout the season.
