86CUP 2020 RULES

Changes or clarifications for 2020 season are highlighted in red.


Cars are classed into 4 different classes according to their level of preparation. A driver can only sign up for one class per event.

Drivers can earn championship points in all classes up until (and including) the September 2020 event. After the September event, drivers who have entered more than one class can no longer switch for the rest of the season and must communicate the board which class they are sticking with. Clarification: Switching classes after September 2020 event will result in forfeiting Championship points earned in rounds entered between October and December. Similarly, after the September 2020 event, drivers who have not entered any prior 2020 events will not be able to earn championship points for the rest of the season -event finishing positions are kept, but championship points for event will be awarded only to qualifying competitors as if non-qualifying drivers had not participated .


The purpose of this class is to keep costs to a minimum and be attractive to a drivers with stock or minimally modified vehicles. Drivers of all experience levels are welcome. Starting in 2020, the Stock Class no longer uses a Points System. Instead, participants are only allowed car modifications included in the following list:

- Aftermarket Oil Cooler

- Camber Bolts for Front Struts

- Camber Plates for Front Struts

- Rear Suspension Lower Control Arms

- OEM Wheels (including STI/TRD 18 inch)

- Aftermarket Wheels: 17” only, up to 8” wide

- GT Radial SX2 / HPY or OEM Tires in OEM sizes

- Maximum tire width 225

- OEM Front STI/TRD lip only if equipped from the factory

- Any item in Section 5 (“Free Modifications”) of the 86CUP points calculator

- Replacing Stock Class-legal OEM parts with newer/older Model Year replacements is allowed (e.g. bumpers, exhaust manifold, intake manifold, sway bars, etc).

- Only OEM or OEM equivalent engine maps are allowed (no custom traction control, higher redline, etc)

- No lightweight replacement parts are allowed (like battery, CF trunk etc). Spare tire removal is OK.

- Rear spoilers not on base trim model are NOT allowed (e.g. RS1.0 or TRD spoiler).

- Grace period: 2019 Stock Class drivers whose car builds were legal in 2019 but not under 2020 rules, are allowed to participate in the January 25/26 double header event with the same *unmodified* Stock Class-spec car they last used in 2019.

STREET CLASS - 4.0 modification points max

The purpose of this class is to allow moderate modifications to a primarily street-driven car. Drivers/owners are granted flexibility in choosing different modifications, while competing in an even playing field. Street class cars typically feature one of three major areas of modifications: aerodynamics, forced induction, or substantially increased mechanical grip.

- Only tires from the 86CUP pre-approved tire list are allowed.  If your tire is not allowed, please contact a board member for evaluation.

- 2850 lbs minimum weight with driver and FULL tank of gas.

MODIFIED CLASS – 7.0 modification points max

Modified class cars are expected to have several dedicated performance modifications. Cars in this class will typically have two of the three major areas of modifications: aerodynamics, forced induction, and mechanical grip, and are usually readily identifiable as a track driven car.

- Only tires from the 86CUP pre-approved tire list are allowed.

- 2750 lbs minimum weight with driver and FULL tank of gas.

UNLIMITED CLASS - Unlimited modification points

As long as you have a FT86 chassis with an FA20 engine (modified or not), anything goes!

- There is no restriction on allowed tire sizes, brands or models.

NOTE: 86Cup reserves the right in exceptional cases to re-classify any car it deems belongs in a different class, regardless of the total number of modification points.

Disallowed Across All Classes




Each class except Unlimited Class has a minimum weight: at any point during the day, a competitor with driver inside must meet that minimum weight. If and when a competitor is found to be below minimum weight, he will be penalized 1 second for every 25 pounds he is under the minimum weight. If this is the competitor’s first violation, the first 25 pounds will be allowed as leeway (for possible scale-to-scale variation), but he will be penalized for any further discrepancy. Also, if this is the first violation, he may choose to forfeit all laptimes he has accrued until the weighing process, add back weight to his car to meet minimum weight, and re-start new timed laps instead of taking a lap-time penalty. Any repeat violations will automatically incur the lap time plenty as outlined above.

Weighing Protocol

One competitor from each class may be selected at random to be weighed at any time during the day. The probability of being weighed is directly proportional to the number of points he has accrued throughout the season (for example, this is equivalent to adding one’s name in a hat once for every point he scores, then drawing from that hat at random). That means top drivers have the highest likelihood of being weighed, and drivers who have yet to score points will never be weighed.

Weighing Logistics

Two drivers from each class may volunteer or will be randomly selected to participate in the weighing process. Only drivers from a different class may weigh one class (to create impartiality). For example, if a Stock class participant is being weighed, only the two drivers from Street and two drivers from Modified may assist in the weighing process. All who participate in the 86CUP implicitly agree to help with the weighing process if called upon, barring any extenuating circumstances.


Championship points for each class will be distributed according to event results. The finishing position for a driver in a given event is determined by their fastest recorded lap time achieved during a competition session. Competition sessions will always be 2, 3 and 4 unless otherwise communicated. Championship points awarded based on event finish position:

1st - 10 points,

2nd - 7 points

3rd - 5 points

4th - 4 points

5th - 3 points

6th - 2 points

7th or lower - 1 point

No extra championship points may be awarded beyond what is outlined above.

Only events that are announced at least 3 weeks ahead of time can be counted towards championship points. If an event is added or moved to a different venue within 3 weeks of its date,  any points awarded during that event will not count towards the championship.

86CUP reserves the right to update rules during a competition year in exceptional cases. For updated rules to apply to any single event, they need to be announced at least 3 weeks ahead.

The best 7 finishes of 10 events will count toward the championship for each class.

In the event of a tie, the participant with more 1st place finishes will be awarded the championship. In the event of a tie after the first tie-breaker parameter, the participant with more attendance will be awarded the championship. If there is still a tie after the second tie-breaker parameter, the participant with the faster time at the Mazda Raceway Laguna Seca event will be awarded the win.

Prizes at individual events for each class will be awarded regardless of number of competitors in the class. Year-end prize winners need to have participated in at least 5 events. Unclaimed prizes and prizes without a winner will be thrown into a raffle pool to be raffled to participants at the end of the year. One raffle entry will be issued to every 86/FRS/BRZ owner who attends the season finale, even if they do not participate in any 86CUP events.


A competitor may also be spot-weighed if two peers (or at least half of the participants of that day, whichever is less) from the same class believe the competitor to be in violation of minimum weight. That competitor will be liable to be weighed on the spot. In addition, if a competitor suspects another is underrepresenting his points, he may bring his concern to a member of the 86CUP board immediately, so that a board member can audit the car at that point, and compare the setup to that declared on the signup sheet. If a participant fails the audit, he can choose to: 1) correct the violation and forfeit all a previous laps and redo timed laps for any remaining sessions; or 2) take a 1 second penalty for every 0.25 points he is over the limit.


Barring exceptional situations, all in-season rule changes will be announced 90 days ahead of enforcement.


To mitigate the impact of new tires coming to market during the season, Street Class and Modified Class participants are only allowed to use the tire models pre-approved in the list below. New tires may be added to the list at any point during the season, once the 86CUP board has been able to assess their performance from real on-track data, regardless of their official UTQG rating.
