Test and Tune
You’re welcome to bring almost any truck or car to run test passes at our track. We call up Test and Tune as its own group between competition rounds, and you get more passes as the day goes on and competition rounds progress quicker. We require a helmet for any vehicle that runs faster than 14 seconds in the quarter mile, and a cage is required for anything faster than 10 seconds. If you don’t know what you’ll run and your vehicle is expected to be quick compared to a minivan, wear a helmet.
