ATTENTION: All vehicles, drivers, and crew must meet the safety and equipment requirements of the 2026 BCCR. Stint maximum of 2 hours per driver with a minimum of 1 hour between stints.
NOTE: Testing, tuning, brake bedding, high speed accelerations or braking will be limited to the track, and not allowed in the paddock or surrounding public roadways. Doing so could result in event expulsion with no fees returned.
All fueling is to be completed on pitlane race day. Do not store fuel in the garages.
Race Car Tech Inspection: All teams will be required to do the Online Tech Form. The team captain will log in at https://champcar.org/register/login.php to complete the race car online tech form. The Team Captain will find a button link on the main login page. Three months before the race, the tab Submit a Tech Form will take you to an electronic form that looks just like the paper Tech Inspection form. Fill in the boxes at the top, then fill in or click on the listed point value items on your car. Save the form and you are done. At the track the Tech staff will simply check the required safety items on the car. Once the Tech staff clicks save on the safety portion of your online form, you will get your annual tech sticker and head to ChampCar registration.
Please verify your timing and scoring transponder and Flagtronics FT-200 serial numbers, and make certain to add your car class to the tech form.
