Pre-Race Inspection

All cars must go through pre-race inspection. A Kajun Mini Stock Association official will check the carburetor, suspension, chassis, drive line and punch the tires. A decal will then be applied to the car with the weight information obtained during pre-tech. Any car found to be illegal during pre-tech will be given the opportunity to correct the issues before qualifying or the heat races. If anything is changed on the car before qualifying and/or heat races, the car must go back through pre-race inspection.

Post-Race Inspection

The top 6 cars in the feature must across the scales and then proceed to the Kajun Mini Stock Association tech tents unless directed otherwise by Kajun Mini Stock Association official. No stops in pits! Any car that goes to their pit area before going to the tech tents will be DISQUALIFIED. A final inspection will be conducted. The Kajun Mini Stock Association will determine what will be checked. This information will be compared to the original information and against final weights. At that point a final pass or fail decision will be made. If anyone wants anything else to be checked it will fall under the protest provisions.
