Go to motorsportsreg.com. If you haven't done so, create an account. Easy, cheesy.
Under the 'calendar' section, search for races. Narrow the focus by selecting 'club race' under 'event type'. Click on 'search'.
On the right side is a green button that'll connect you to the race's registration page.
Call if you need some guidance (517.889.1100)
