86 Challenge (formerly 86DRIVE Challenge) is the premier, independently organized, GR86/86/BRZ/FR-S Time Trial series in Northern California. Utilizing an easy-to-understand ruleset specific to the platform, the 86 Challenge aims to provide a friendly, safe environment in which 86 enthusiasts can hone their driving skills. Come join us at our events to compete, get a ride, or spectate to experience the true capabilities of the platform in its natural environment!
For 2025, we'd like to welcome our new sponsor, RaceTreads.com as the title partner for the 86 Challenge, partnered with our long-time sponsor GT Radial! RaceTreads and GT Radial passionately support the world of racing and high-performance driving, offering premium service and tires to meet your needs.
We will be running most of our events with SpeedSF. They have been very accommodating of us in the past, and we look forward to another successful partnership this season.
