RRR Test & Tune

Grand Junction Motor Speedway

About this event

Cars will be grouped by lap times (estimated for new drivers) and you'll be racing the clock, no wheel to wheel. Come out and have some fun. GJMS is sort of a brdige between auto-x and a full road course. At .9 of a mile with 15 turns and the fastest cars reaching about 75-80 MPH it's a very fun track. Each session consists of a warm up lap, 4 hot laps, and a cool down laps. Most events you'll have 4 to 5 sessions throughout the day. Gates open at 7am, tech starts at 7:30. There is a mandatory drivers meeting at 8:30 and cars go on track at 9am. Spectators are free, but anyone in the pit area needs to sign a waiver. Waivers for minors are also available. This is a test & tune day so there will be no official timing.
