Race format
Nitro races use fastest-lap scoring, so the best single lap wins rather than a simple first-across-the-line finish.

FAQ
The actual answers.
Short answers to the questions we hear the most.
Do I need a membership before I can book?
Yes, but the starting point is simple: Walk-In membership is free. It is the normal path for online booking, free helmet rental, and first-time visits.
How early should we arrive?
Plan to arrive about 30 minutes before your event. That gives enough time for waivers, check-in, gear, and keeping the handoff into racing or activities smooth.
What are the karting height requirements?
Junior karts require a minimum of 4ft tall. Adult karts require a minimum of 5ft tall. Nitro does not run adult and junior karts simultaneously in the same race.
Is there an age limit for racing?
The operational rule is mainly height, not age. If a racer meets the height requirement for the kart class, that is the important filter.
What shoes or gear do racers need?
Closed-toe shoes are required. Full-face helmets are required and provided at no cost. Headsocks are also required.
Do minors need a waiver?
Yes. All karting participants need a waiver, and minors need one signed by someone 18 or older.
What is the birthday-party minimum?
Birthday party bookings currently start at 8 participants. If the count is still moving, the safest move is booking the minimum confirmed number first and then adjusting with the coordinator.
Who should I call for a party?
For birthdays, use the party coordinator at 707.800.4900 ext. 1. General questions can still go to 707.800.4900.
What is different about Rohnert Park vs. Fairfield?
Rohnert Park is the OTL Superleggero / pool-table location in Sonoma County. Fairfield is the SODI RSX2 / Mini Golf / Pixels location in Solano County.
Headsocks
Headsocks are required for karting, even though helmets are provided free.
Friday students
Students get 20% off races on Fridays, redeemed in store.
Still stuck?
Call the right line. Skip the guessing.
General questions belong on the main line. Birthday questions belong with the party coordinator.
