Test & Tune

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 are named Wild Wednesdays, Fridays are Fun Grudge and once a month during the Fun Grudge US 131 features a Midnight Madness.   There are at least two Wild Wednesdays per month, several Fun Grudge and one Midnight Madness event.

Wednesdays

Participants will not want to miss these bargain nights. The US 131 Motorsports Park staff will be available to assist anyone interested in learning more about drag racing and bracket racing.  We will run open time runs for the first part of the event.  Drivers will then be able to place a dial-in on their car, if they choose, and run just as if they were running in an actual bracket race.  All just for fun to see who can take the win light!

Gates open at 5pm, racing from 6pm to 10pm.
Admission for spectators $8
Racers pay only $20 

Friday Nights

Friday Nights include an open Test & Tune for any and all vehicles, novice or seasoned racer. Similar to Wild Wednesdays, drivers can make unlimited time runs all evening and pair up against other racers for grudge matches. Whether you want to just test your vehicle, run against one another or just hang out with friends this is the place to be on Friday nights.
