Test & Tune is open to everyone where running down the “Fastest Track in Michigan” is more than just excitement, it’s pure adrenaline!

For racers who compete often at US 131 we are offering Advanced Tech Inspection (ATI) for only $10 per vehicle.   Our technicians will inspect each vehicle and after passing inspection you will receive proof of this to be used all year.     This will save you time in the tech line at each event.    It is fast and convenient for everyone.

To further accommodate our racers we are offering a chassis certification here at US 131 Saturday, April 18 from 9am-5pm.  To book your appointment for the ATI and/or chassis certifications, please call the track office, 269.672.7800 from 9am-5pm to make an appointment for any Saturday in April.  

Saturday’s Test & Tune events run all Saturdays in April from 12 noon-6pm.   Testing is only $20 for unlimited time runs, adult gate admission $12, children ages 6-12 are $5 and children 5 and under are free.
