What's 86DRIVE Challenge?

86DRIVE Challenge is the premier, independently organized, FRS/BRZ Time Trial series in Northern California. Utilizing a ruleset that is specific to the platform, the 86DRIVE 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 2018, we'd like to welcome back GT-Radial as the title sponsor for the 86DRIVE Challenge! GT Radial has been a sponsor for us since the beginning, and this year, they're continuing to generously giving away cash prizes for the podium winners of the Stock and Street classes in addition to the tire Contingency program. See below for details! Returning this year to continue supporting our series are Winmax, Elite Performance, and 86DRIVE. Each have been instrumental in the past to help build the 86DRIVE Challenge series to what it is today, and we look forward to working with these sponsors again this year!

Joining us as sponsors for the 2018 season include The Racers Line, Bluemoon Perfomance, and Verus Engineering!

Once again, GTRadial will be sponsoring a Championship Cash Prize and Tire Contingency program for 2018! Details coming soon, so stay tuned!

This season, we will be running all of our events with SpeedSF. They have been hosting safe events for us in the past, and expect nothing different this year.

Please visit his website to see the awesome pictures that he has taken for us: Contact Scott directly for information on purchasing pictures. Thanks, Scott!


What mods do I need to start tracking my 86?

Contrary to what many people think, you actually don’t need much to begin tracking! For your first few track days, you’ll just need proper track brake pads, and good brake fluid. We can recommend Winmax W5 for brake pads and Motul RBF600/RBF660 or Project Mu G-Four 335 for brake fluid. An oil cooler is also highly recommended, but typically not required for your very first track day. That’s it! You don’t need fancy suspension parts or super sticky tires to come out and have some fun!

I’m new to the track with many mods on my car, and I’m concerned that I won’t be competitive in the higher class that my car will fall into. What can I do?

No worries! We have a “Sport” class for drivers who feel that they’re not quite ready to be competitive, but still want to join us at the track. In the “Sport” class, we’re less focused on the mods that you have, and want to allow you to get up to speed without worrying too much about competing. With many veteran drivers at each event, you’ll have the chance to ask for driving advice, or even sit with them for a couple laps to learn the ropes. The most important step is just to come out to the track!

My car is stock. It’s no good for the track, right?

Absolutely not! In stock form, down to the “Prius” tires, the 86 is actually very capable, and a perfect platform for new drivers to learn and refine his/her driving skill. We have a “Stock” class for 86’s with little to no mods so you can focus on driving and not worrying about mods and adjustments. As some would say, “stock is best!” Here are some in-car video footages of stock class drivers showing what the platform can do very few mods:

Will braces/tires/wheels/suspension/FI/engine swap mods make me faster on the track?

Not necessarily. You will certainly feel a difference from most of these mods, but we actually recommend you save some money and start out with a simple setup, and only start modding after you've had a chance to see what the basic platform can do. That way you only spend money on things that you think need improving, after you've had a chance to experience the car in what we think is an already capable form. Many of us have learned the hard way and actually removed mods from our cars, and have gone faster!
