86CUP CLASSES
Stock Class - 0.5 points maximum
The purpose of this class is to keep costs down and be attractive to a newcomer with a stock or minimally modified FRS or BRZ. Drivers of all experience levels are welcome. Tires are restricted to TW 140+ and no larger than 225 width.
Certain modifications are not allowed in Stock class:
- No Level 2 Front Aero
- No Level 1+ Rear Aero
- No Level 1+ Rear Wing
- No light-weight aftermarket parts, no aftermarket body panels, or any interior removal (unless necessary for safety equipment).
- No forced induction
Street Class - 3.5 points maximum
The purpose of this class is to allow moderate modifications to a primarily street-driven car. Drivers/owners are allowed flexibility to choose different modifications, while being exposed to an even playing field. 2850 minimum weight with driver and FULL tank of gas
Modified – 6.5 points maximum
Modified cars are expected to have a myriad of dedicated performance modifications. Cars in this class will typically either have a large amount of power and/or are easily identifiable as a track driven car. 2750 minimum weight with driver and FULL tank of gas.
Super Modified - 10 points maximum
Minimum weight for Super Modified Class is 2700 pounds with driver. Who knows what you may see in this class...

WEIGHING
Rules
Each 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 group (Street and Modified) will 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 S2KC implicitly agree to help with the weighing process if called upon, barring any extenuating circumstances.
PROTEST PROTOCOL
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 ]
