Colorado RallyCross

Welcome to Colorado RallyCross!  What is RallyCross?  Think of it as autocross gone wild.  Instead of a paved parking lot, we race on gravel or dirt under all types of conditions—dust, more dust, mud, rain, snow, ice, wind, and even darkness.  If you’re new to RallyCross, check out our website for more information about the most exciting entry-level motorsport on the planet!  If you’re a RallyCross veteran, be sure to mark this year’s events on your calendar.  We hope to see you at the next event!

Tech Inspection Checklist
Written by Jerry S.   

All competition vehicles are required to pass a technical inspection prior to competing.  The purpose of tech inspection is to ensure your car meets basic safety requirements.  Please note—passing tech does NOT mean your car complies with the rules for your particular car class. It is the drivers responsibility to follow the class rules for your particular car class.

Here’s your guide for getting through tech inspection quickly and cleanly.  The complete technical requirements are described in the SCCA RallyCross rules, but this checklist will give you an overview of what our tech inspectors are looking for and common problems they encounter when inspecting cars.  It is very important to have all of these issues taken care of and your car ready for inspection as soon as possible when you arrive at an event.  Tech problems and re-inspections cause delays for other drivers waiting for tech and could potentially postpone the start of the event—a very bad result!  Also our volunteer tech inspectors like to finish tech on time so they can walk the course like the rest of us.  If you take time to make sure your vehicle meets the requirements listed below before you arrive at the event, you’ll pass through tech with flying colors and be ready for some seriously fun rallycross action.


1. Remove all unsecured items from the passenger compartment of your vehicle. No loose items allowed anywhere in your vehicle’s interior.  Period.  This includes floor mats, maps, loose change, radar detectors, speakers/sub-woofers that are not mounted, cans, and anything else that is not bolted to the vehicle.  In-car cameras must be securely mounted before going through tech.  It is a good idea to bring a plastic storage bin to store your stuff while you are racing and working.  Be prepared to leave everything, (including the change in the ashtray) at your paddock parking spot for the entire day.  Not a bad idea to bring a tarp to protect your stuff from dust and the occasional rain or snow shower.

2. No loose items in your trunk.  Sounds silly, but we occasionally have drivers show up to race with junk in their trunk.  Once we even had a competitor with a spare transmission rolling around in his trunk!  We don’t want a transmission, a loose jack or anything else to come shooting out of your trunk and injure someone, so be sure to empty your trunk.  Also, make sure your spare tire is secure.  Rallycross rules allow you to remove the spare tire, jack and tire tools from your vehicle.

3. Tech inspectors will check your brake pedal freeplay and your throttle return.  If your brake pedal goes all the way to the floor or your throttle sticks, be sure to fix it or you won’t pass tech;

4. Helmets are required for drivers and passengers.   All helmets meeting the latest or two immediately preceding Snell Foundation standards (SA2010, SAH2010, SA2005, SA2000, M2010, M2005, M2000, K2010, K2005, K98), SFI standards 31.1, 41.1, 31.1A, 31.2A, 41.1A, 41.2A or British spec BS6658-85 type A/FR are acceptable.  Helmets that are DOT-rated-only will not pass tech.  If you have a helmet but are not sure of the rating, look first for the Snell rating on the back of the helmet.  If there is no Snell rating on the back (which is common), you can lift up the liner inside the helmet and look for a Snell sticker.  It is most often on the sides of the interior underneath the liner.  Loaner helmets will be available at the event if you need one.


1. Battery must be tied down securely.  This is the most common problem identified by tech inspectors.  The battery should be securely fasted so it doesn’t go dancing across your engine bay, start a fire and cause your car to burst into flames.  Bungee cords, rope, straps, bailing wire and zip ties are examples of but not limited to none approved tie-downs methods.  If your battery will not tighten down enough to absolutely minimize movement, stop by your local auto parts store and get an inexpensive battery tie-down kit;

2. Positive battery post must be covered.  The factory terminal cover is preferred or you can wrap the positive terminal with black electrical tape;

3.  No excessive leaks.  A bit of a drip is fine, but we don’t want oil or other liquids pouring out and neither should you.

4.  No bare wires in your engine bay.  Replace exposed wires or cover with electrical tape.


1. Make sure nothing is falling off your car.  Be sure bodywork, trim pieces and under-car shields are securely fastened.  If you do have a loose piece, secure it in place or remove it from the vehicle. And definitely no hanging mufflers, which must be fixed while still exiting the rear of the driver.

2. Sunroofs must be closed.  No convertibles allowed unless you have a factory hard-top in place.  Make sure any bicycle/snowboard/ski rack is securely attached;

3. Side Windows: The driver’s window may not be down more than 1” during course runs unless the vehicle is equipped with a window net and/or the driver is using arm restraints. The same restriction applies to the passenger window if there is a passenger.

4. Make sure your hood and trunk is latched securely.  If your latching mechanisms are a bit questionable, install a set of hood pins and/or trunk latches available at most auto parts stores for not a lot of coin;

5. Make sure you have your fuel cap.  More than once someone has left their fuel cap at the gas station when they fueled-up before a race.  For obvious reasons, a car without a fuel cap will not be allowed to compete;

6. Make sure your wheels are securely mounted.  Tech inspectors check for wheel bearing play, so make sure you don’t need new wheel bearings.  Some play is ok, but excessive movement may be an issue.  Bearings that screech or squeal are definitely not going to pass tech.

And there you have it.  Follow these simple steps and you’ll pass tech in a flash.
