The Procedure

The purpose of a track inspection is to check important components of the vehicle to ensure the safe condition of the vehicle.  The world is an imperfect place, so even a vehicle which passes inspection could still experience an issue on track.  That said, most well-maintained vehicles inspected on a regular basis will be less likely to have problems at the track.

Track driving will put some additional stress on your vehicle; similar to how exercise puts some additional strain on your body but overall, this is good for you – the same is true for your car!

We’ll begin by discussing some of the basics of a track inspection:

  • First, check the overall condition of the vehicle – does it show any body damage, rust, or corrosion.  Make sure the battery is properly installed, not leaking, and is securely mounted.
  • Brakes are critical components when on track – check all four corners (inner and outer pads) to make sure the pads are of sufficient thickness and the rotors are above minimum thickness.  Check the hoses and hard lines carefully for any damage, wear, or weathering.
  • Aftermarket stainless hoses are great upgrades, but have a shelf-life.  Do not learn this the hard way!  Most sources will recommend regular, routine replacement of stainless lines as part of your vehicle maintenance.
  • Check the brake pedal to make sure it holds with steady pressure and check that the brakes are not pulling or dragging during a road test.
  • Make sure all brake lights work.
  • Brake fluid should be at an adequate level and in good condition.  Fluid onboard must be at least 6 months old – anything older than 6 months should be flushed.  Many track drivers flush brake fluid before each event – it’s cheap insurance.
  • Check for any leaks or looseness in the drive and half shafts.  Make sure the flex coupling and center support bearing does not show any cracks or worn condition.
  • Drive and accessory belts should be properly tensioned and in good condition – cracked belts should be replaced.
  • Check engine, transmission, and differential mounts to make sure they are secure with no excessive movement or wear.
  • Make sure the exhaust is securely mounted and in good condition.
  • Visually inspect all fuel and coolant hoses – check for cracks, swelling, or other wear/deterioration.
  • Inspect vehicle for any fluid leaks – coolant, brake, fuel, power steering, etc.
  • Make sure the mirrors are securely mounted and functional.
  • Check the condition of the pedals, seatbelts, and seats.
  • Steering should be checked for excessive travel or binding.
  • Suspension items to inspect include all mounting points (including subframe bushing mount points), make sure there are no leaks from shocks/struts.  Check the condition of the springs.
  • The throttle linkage should be free to return without binding throughout its travel.
  • Tires – this is your only connection to the road surface, make sure they are in good condition.  Most events recommend a minimum 3/32″ tread depth.  Make sure the tires are properly inflated, with no cracks, blisters, or cord showing.  Front tires and rear tires should be the same size.
  • Wheel bearings – check for play; zero tolerance on this.
  • Wheels – check wheels for bends or cracks; make sure the lug nuts/bolts are properly torqued.
  • Windows and windshield wipers should be checked too.  Verify operation of the wipers.
