Preparing your car for tech inspection
Tech inspection is a basic safety check before your car goes on track. It typically covers brakes and fluid, tires and wheels, wheel bearings, leaks, the battery tie-down, loose items in the cabin, seat belts and your helmet. It isn’t a guarantee that your car is safe, and requirements vary by organizer, so always use your event’s own tech form.
- Get the organizer’s tech form early. Some require a mechanic’s signature days before.
- Brakes, tires and anything that could come loose are the core of every inspection.
- Remove everything loose from the cabin and trunk, including floor mats.
- Passing tech means the car met a checklist. Keeping it safe is still your job.
How tech works
Some organizers inspect cars at the track in the morning. Others use a self-tech form or ask a shop to sign off the car before the event. Either way, the inspector works through a checklist and puts a sticker on the car or signs your form.
Requirements differ between organizers and between run groups. Read your event’s tech form before you start, because it’s the only list that counts on the day.
The common checklist
- 1Brakes: pads with enough material left (often around 50% or more), no cracks in the rotors, a firm pedal.
- 2Brake fluid: fresh and not discolored. Many organizers recommend replacing it within the last year, and high-boiling-point fluid is a good idea.
- 3Tires: good tread, no cords, bulges or cuts, and the correct pressure.
- 4Wheels: lug nuts torqued to spec, all present, no cracked wheels.
- 5Wheel bearings: grip each tire at the top and bottom and rock it. There should be no noticeable play.
- 6Leaks: no oil, coolant, fuel or brake fluid leaks, and no loose hoses.
- 7Battery: held down firmly with a proper clamp, with the positive terminal covered.
- 8Cabin and trunk: empty of loose items, including floor mats and anything under the seats.
- 9Seat belts and seats in good condition and securely mounted.
- 10Throttle returns cleanly, and nothing is loose under the hood.
- 11Helmet: meets the organizer’s current rating rule, with the label inside.
Items that often catch people out
Old brake fluid is the classic one, because it looks fine but boils sooner. Next are loose items: a bag in the trunk or a phone mount that isn’t secure. Then helmets with an expired rating, and batteries held down by a strap that’s perished.
Convertibles and some vehicle types may need extra equipment, such as a roll bar. Numbers or class letters on the car are also common requirements. If you’re unsure, ask the organizer before the event, not at the gate.
During the day
Tech isn’t just a morning formality. Check lug nut torque after the first session, look for new leaks every time you come in, and keep an eye on pad wear. If a warning light appears or the pedal goes soft, stop and get the car checked before you go out again.
FAQ
What happens if my car fails tech?
Usually you’re given the chance to fix the problem and come back. If it can’t be fixed at the track, you may not be able to drive that day. That’s why doing your own check a week early is worth it.
Do I need a professional inspection?
Some organizers require a shop signature, others accept a self-tech. Even when it isn’t required, a mechanic who knows track use can spot things you’d miss.
Does tech check my helmet?
Usually, yes. Bring it to tech, and check the rating label inside against your organizer’s rules before the event.
