86CUP 2022 RULES

Changes or clarifications for 2022 season are highlighted in red.

86CUP CLASSES

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 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 event will result in forfeiting Championship points earned in rounds entered between October and December. Similarly, after the September event, drivers who have not entered any prior season 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.

 STOCK CLASS

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:


- 2022+ BRZ/GR86 drivers have their fastest lap of the event adjusted with a 1.5 second time penalty/handicap.This adjusted lap time determines the finishing position in an event among a mix of Gen1 and Gen2 cars. The unadjusted/absolute lap times achieved will be displayed alongside adjusted lap times in the summary of results for every event. The unadjusted lap times will also qualify for new 86CUP or overall 86 chassis track records.

- Aftermarket Oil Cooler

- Camber Bolts for Front Struts

- Camber Plates for Front Struts

- Rear Suspension Lower Control Arms

- OEM Wheels 2012-2020 and 2022+ (including STI/TRD 18 inch)

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

- GT Radial SX2 / HPY

- OEM Michelin Primacy HP or OEM Michelin Pilot Sport 4 in OEM sizes (using these tires may make you ineligible for cash prizes by GT Radial. See https://86cup.us/gtradial)

- Maximum tire width 225

- OEM 2012-2020 Front STI/TRD lip only if equipped from the factory (cannot add otherwise)
- 2022+ OEM duck tail only if equipped from the factory (cannot add otherwise)

- Replacing Stock Class-legal OEM parts with newer/older Model Year replacements is allowed (e.g. bumpers, exhaust manifold, intake manifold, sway bars, etc). Clarifications: use of aftermarket sway/anti-roll bars is not allowed. Only OEM Totota/Subaru parts from MY 2012-2022+ are allowed. Clarification: it is allowed to swap sway bars with newer or older OEM bars.

- 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.

- Cars equipped with full aftermarket safety system (bucket seats, approved racing harness, neck restraint system, full or half roll cage) are allowed to participate in Stock Class as long as total curb weight of the car with ¾ tank of fuel remains above 2758 lb (driver not included). Driver will need to have car weighted at a location approved by the 86CUP committee before they are allowed to enter Stock Class on the current season.

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

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.


- All 2022+ BRZ/GR86 (or FA24 equipped) cars take an automatic handicap of 1.25 modifications points.  Also note that the OEM 2022+ exhaust manifold is also assigned 0.125 points in our Classing Calculator (https://86cup.us/calculator/)

- 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

Must have FA20 (2012-2020 modified or not) or FA24 (2022+) engine.

- 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

Safety

WEIGHING

Rules

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.

EVENT AND CHAMPIONSHIP SCORING, PRIZES

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.

In the SoCal region, the best 7 finishes of 10 events will count toward the championship for each class.

In the Rocky Mountain region, the best 8 finishes out of 12 events will count toward the championship for each class.

For other 86CUP regions sharing this 2020 ruleset, please consult with their organizing bodies.

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 (SoCal 86CUP region) 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.

PROTEST PROTOCOL

If a competitor suspects another is underrepresenting his points, he may bring his concern to a member of the 86CUP board immediately during the day of the event, 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.

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.

RULE CHANGES

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