Autocross

How do you know if your car will pass tech inspection at a THSCC autocross? Most cars that are in good enough condition to drive on a public road without worry are in good enough condition to autocross safely. Check this list, and if you still have any questions, email axtech@thscc.com

Annual Tech

If you are NOT a novice, you are eligible for annual tech. Print out one of these forms, inspect your car, and fill it out. On the morning of an event leave the filled out form on your drivers seat, under the windshield wiper, or somewhere else obvious. When a tech inspector comes around to check your car for the day, if you pass tech, they will sign the form and leave you an annual tech sticker. Keep the annual tech form handy at all events and place the sticker somewhere easily visible like in the lower corner of the windshield.

You can find the annual tech form Here

Regardless of whether you have annual tech, THSCC reserves the right to deem your car unsafe and not allow you to drive during an event if any tech issues are observed.

Day of Event Tech

This is a basic outline of what will be checked by the tech inspectors at an event. These are criteria that are one step below a car with absolutely no issues. THSCC reserves the right to fail a car at tech inspection or at any point during the day, at the discretion of tech inspectors and autocross VPs, for anything that is deemed unsafe, even if not explicitly stated here.
