Greetings and welcome to our fifth local event of 2025! The Commons is located at 1794 E. Baxter Ln, Bozeman, Mt 59718. Driver's meeting is usually around 9:00 am and all drivers need to present for this. If your car needs to be teched or you are unfamiliar with the event location I would suggest getting there around 8:00-8:30 am. This will give you time to walk the course a couple of times. Please bring a lunch so we can minimize downtime.

Due to the growing residential area at Black Bull we will be having to start controlling the sound level of our events. It is our plan to have a 95db sound level for competeing vehicles. If you are usure what your car's sound level is please contact us and we will help. Vehicles with over 95 db will not be able to run at the event location.

Join Southwest Montana region for a fun day of timed competition at The Commons west of Bozeman.

The registration cap for this event is 35 drivers, so if you are coming, please sign up early. If you need to cancel, please do so online, or notify us through the contact button. This will allow for a last minute driver to potentially get to autocross with us.

NEW POLICY: If you register, and no-show without notifying us through Motorsportsreg, you will get charged. This is to help people on the wait-list get in.
