What's 86 Challenge?

86 Challenge (formerly 86DRIVE Challenge) is the premier, independently organized, FR-S/86/BRZ Time Trial series in Northern California. Utilizing a ruleset that is 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, get a ride, and experience the true capabilities of our platform in its natural environment!

For 2024, we'd like to welcome back GT Radial as the title partner for the 86 Challenge! GT Radial has been a partner for us since the beginning, and this year, they're continuing to generously give away cash prizes for the podium winners of the Stock and Street classes in addition to the tire Contingency program. Returning this year to continue supporting our series is Annex Suspension Group. Each have been instrumental in the past to help build the 86 Challenge series to what it is today, and we look forward to working with these partners again this year!

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.
