Central Valley
Saturday morning
September 5
8:00 AM – 4:00 PM

Extreme Speed runs both Buttonwillow and Willow with an open-to-all-cars philosophy, so the pits get a wide mix — track-prepped builds parked next to street cars on their first day.
Track-day series run by Extreme Speed Track Events at SoCal circuits (Buttonwillow + Willow Springs). Open-track / HPDE-style driving days. Dates rotate between venues and configurations.
Good to knowOpen-track / HPDE format at Buttonwillow with sessions sorted by experience. Pricing varies by date; registration and run-group requirements on Extreme Speed's site.
