Please pre-check yourself in such case to ensure you can pass the inspections.

The following is designed to better explain specific points listed on the technical inspection sheet. It is highly recommended that all drivers ensure all points listed below are met, prior to an event to save time and trouble. Although minor repairs can be made on the day of the event, drivers should keep in mind that only one hour is allocated for tech inspection, and failure to pass technical inspection during this period will prevent a driver from participating.


  • Modifications – any modification to a vehicle must meet a standard of safety in design and installation.
  • Hub spacer/ adapter – Hub spacers or adapters must be installed properly and torqued to specifications. Lug nuts used in conjunction with these adapters must retain minimum threading to hold tension and be present on every stud.
  • Engine – Modifications to the engine must not interfere with required safety systems (brakes, steering, etc) of the vehicle. Engine modifications must also not create a fire or fluid leakage hazard. All aftermarket piping must be properly secured to the frame of the vehicle. Vehicles with transplanted engines must have all intake channels, intercooler piping (if present), and exhaust piping properly secured to the vehicle.
  • Suspension – If present, aftermarket roll center adaptors, alignment compensation brackets, and steering linkages must be torqued to specifications and meet required tensile strength.
  • Wheels / Tires – Aftermarket wheels and tires must not rub against the fender of the vehicle.
  • Brakes – Brake systems must be able to handle extended periods of hard driving conditions. Brakes must be properly bled and all seals in good condition, pedal and linkages must be free of excessive wear, play and malfunction or missing parts. Brake pads must have more than 25% of original condition. Master cylinder and calipers must be within specification. Brakes must be free of fluid leaks. Brake lamps must be functioning properly.
  • Body / Suspension – The body of a vehicle must be able to adequately protect the driver.
  • Tires and Wheels – Tires must retain a minimum of 3/32 inch of tread, and not have exposed belting or show any other signs of failure. Minimum tread wear rating for tires is 100 (no race compounds allowed). Temporary spare tires are not allowed on participating vehicles. All drivers must have 2 spare mounted tires that are not used on the course.
  • Lug Nuts – All lug nuts must be torqued to 80 ft/lbs. on approved fasteners, and be used on every stud. Lug nuts must have a minimum of 4 turns worth of thread.
  • Steering System – Steering system and linkages must be in proper working order.
  • Suspension – Suspension bolts must be torqued to specification. Suspension mounts must not be damaged.
  • Windows / Windshields – Windows and windshields must be free of cracks or breaks over 1 inch in length, or 0.5 inch in diameter.
  • Body Panels – body panels must be present and secured by fasteners.
  • Aero Parts – Rear wings, spoilers and other aerodynamic or cosmetic additions must not protrude over 2 inches over the overall width of the vehicle.
  • Engine – The engine must be able to perform safely under hard driving conditions
  • Battery – The battery must be secured by a standard battery bracket, and at least one terminal covered by proper electrical insulation.
  • Air Cleaner – The intake air cleaner system must be adequately secured to the frame of the vehicle with proper fasteners.
  • Oils and Fluids – All necessary fluids such as engine oil, transmission oil, brake fluid, and other important engine fluids must be filled to manufacturer specifications. Leaks of any of these fluids are not permissible.
  • Throttle – The throttle action must be smooth and the throttle spring must be to specification.
  • Ignition / Fuel System – The fuel system of the vehicle must be responding properly and free of any leakages. Any wiring or tubing associated with the fuel delivery or ignition system must be clear of hot areas to prevent potential fire hazards.
  • Wiring Harness – Any insulation associated with the wiring harness must not present a potential fire hazard (i.e. clear of hot areas of the engine).
  • Exhaust System – The exhaust system of a vehicle must be properly secured to the frame of the vehicle.
  • Safety Equipment – All forms of performance driving require proper safety equipment be functioning on a vehicle
  • Helmet – For practice events, a Snell rated SA95 / SM95 helmet (or newer) is required. DOT only approval is not enough. Loaner helmets are not available.
  • Seatbelts / Harnesses – Seatbelts must be properly attached and in good working order. If present, aftermarket racing harness all points must be attached to the chassis by methods approved by manufacturer, and must meet racing use requirements.
  • Roll Bar (Convertibles / Open Topped vehicles) – All convertibles / open top / soft top cars must have roll bars equal or exceeding 4 points and be connected to the unibody or sub frame.
  • Tow Hooks – Tow hooks must be present on at least one location on the vehicle.
  • Loose Items – Any loose items in the vehicle including floor mats or aftermarket audio systems must be removed.
