Sonoma Test Day registration (not part of the POC registration)


We will have split starts and split qualifying to be determined by class entry counts.

The cost of this event is dependent on the number of drivers who attend. We anticipate that the cost will be approximately $1000, based on 40 drivers attending. We will not be offering the Early Bird Special discount for this event as our pricing reflects the minimum the Club needs to cover costs. Last second registration at the track will be $100 higher than online pricing-no exceptions so register now. Event cancellations must be received by Friday June 30th at midnight for a full refund.

Saturday Morning Check-In: Check-in will be available Saturday and Sunday morning at a registration location to be assigned. 

Garages: There are a limited number of garages available to rent @ $200 for the weekend. They are 2 car (nose-to-tail) garages and will be held on a first come, first served basis in registration. Garages will become available Friday evening after 6:00 PM.

Vehicle tech inspection should be done at an official POC Tech Inspection Station before you get to the track to avoid check-in delays and last minute repairs. Tech inspection at the track will be provided by PRO Motorsports and Vali Motorsports. The cost is $20, payable to POC.
