I. Autocross (SCCA "Solo")
What are we checking?
We will look for things like loose wheel bearings, steering wheel play, or anything unsafe for autocross conditions. Make sure your battery is held tightly in place, the throttle return works, the brakes function, and that nothing is leaking. Note: adequate mufflers are required, as excessively loud cars are one way to make us lose our site.
Tech inspectors are not responsible for judging correct car class, just that your car is safe to autocross. It is a good idea to read the SCCA Solo Rules at SCCA.com or ask for guidance on these forums before you reach registration - we'll be glad to answer your questions beforehand.
For the full text of the vehicle safety rules, see section 3.3.3 of the Solo Rules.
1) All loose items inside and outside the car must be removed, and this includes hand held devices.
2) Passenger's seat back and all cushions, bolsters, headrests, etc. must be secured. All allowed aftermarket replacement seats (i.e., driver and passenger) must be securely and safely mounted.
3) Any cameras must be securely mounted inside or outside the car to withstand loads from driving maneuvers. Mounting method and position must not interfere with driving or pose an additional hazard to occupants or workers.
4) Snap-on hubcaps and trim rings must be removed.

B. The top of the roll structure may not be below the top of the driver's helmet when the driver is in the normal driving position.
9) No excessive fuel, oil, water or brake fluid leaks. Prepared and Modified classes: make sure to read the rulebook about vent lines and cooling lines.
10) No steering spinner knobs are allowed, just in case you just arrived from the 1950s.
11) No cracks in wheels. On wire wheels, no broken or missing spokes or more than one loose spoke per wheel. Only FSAE-class cars may have non-metallic wheels.
12) Brakes must have an adequate pedal, sufficient fluid in the master cylinder, and no apparent hydraulic leaks under pressure.

Any wet-cell battery moved from the manufacturer's original location shall be in a non-conductive, marine-type container or equivalent and the "hot" terminal shall be insulated. NOTE: This will allow the use of gel cell or dry cell (AGM) batteries without a non-conductive, marine-type container where applicable.
