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 - 4.0 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

Limited – 7.0 points maximum
Modified cars are expected to have 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.

Unlimited - no maximum
Minimum weight for Unlimited is 2700 pounds with driver and full tank of gas. Who knows what you may see in this class... anything goes!

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 limit.

Prizes
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 atleast 6 events. Unclaimed prizes and prizes without a winner will be throw into a raffle pool to be raffled off at the end of the year. Each participant will get one raffle entry for each event attended. Additionally, one raffle entry will be issued to every FRS/BRZ owner who attends the season finale, even if they do not participate in any 86CUP events.

Scoring:

1st - 10 points
2nd - 7 points
3rd - 5 points
4th - 4 points
5th - 3 points
6th - 2 points
7th+ - 1 point

So a couple of questions:

Why are am axles free and drive shaft costs points?

Second, why is an E85 tune same cost as an am trans?
And for that matter the springs too.

Seems like a very high price to pay for springs and an E85 tune.

Just sayin'

Awesome job though.

D

Axles are a common failure, regardless of modification level. However, with enough power, a driveshaft becomes a requirement, so it's a way to get the guys with more power.

E85 has huge power gains, regardless of power level. AM trans is another gate for the high power guys. Anything over 325lb/ft torque tends to eat trannies...

As discussed via email, my only concern is with the allowance of FI in Street Class.

I am not particular on this point, just want to make sure we are all on the same page on this with some feedback from outsiders..

Bump

With the tire rules as listed, the Hoosier A6 (or A7) and Hoosier R6 (or R7) would receive the same number of points. All 4 of these tires are UTQG 40 C A. The A6/A7 is a much softer compound developed for Auto-X and time attack applications which will have a huge advantage over the R6/R7.

This will also apply to any other DOT 2-Groove R-Comp that has multiple compound options: BFG R1/R1-S, Hankook Ventus Z214 C51/C71/C91.

Looks very much like the SuperMiata rules setup.


You familiar with Emilio and 949? :)

Oh very much so... although technically this is a more mature series than SPM unless you include Miata Challenge.

That is correct.

The multiple compound thing applies to a lot of tires, so it is assumed that the stickiest version will be used.

Keep in mind that most competitors are casual, and will not run a tire that is only good for one heat cycle/lap. If someone wants to show up to every event with a set of sticker tires, they're more than welcome to do so. So far, outside of Robispec in 2013, nobody has ever shown up on anything anything sticker than a NT01 or RC1, and at that point, it was proven that the A6 was not "worth the points" based on today's system.

IDK, I doubt anyone with FI will be under 4.0.

FI kit, 9" wheels and 245 tires are already 3.75 pts, just 0.25 shy of the 4.0 maximum for Street. I'd expect 99% of the boosted guys to have at least springs, LCAs and some exhaust parts..

Rules look good, we're excited for next year. We'll be in the Street Class for 2015 season!

I know I'm looking forward to getting in as many track days as I can for 2015 :D

Let's see how my mods add up:

□ 0.25 - Any aftermarket intake system or modification to OEM intake (including Filters, except TRD drop-in)
□ 0.25 - Any aftermarket header without a catalytic converter
□ 2.50 - Any Forced Induction (e.g. AVO, Greddy, Jackson Racing, Innovate, Kraftwerks, Vortech, etc); must take separate penalties for ECU, and header as applicable
□ 3.00 - Level 3 R-compound tire (0-50TW, DOT)
□ 0.25 - 225 width tires
□ 0.125 - 5-7.5" width aftermarket wheels
□ 0.125 - Any rear lower control arm
□ 2.00 - Any aftermarket damper with any aftermarket spring, or any coilover suspension

Total Points: 8.5

Looks like the tires I bought on closeout sale are worth more points than my Super Charger and put me in the unlimited class :lol:

All that and I bet I'm still slower than any half decent driver in the Stock class :bonk:

Oh well, as long as I have fun that's all that I care about :thumbup:

Excuse my ignorance, but is this a time trial/time attack series or wheel to wheel racing?

I'm an outsider looking in, but I've got some feedback. If this isn't wheel to wheel I might try to run an event or two but I wouldn't compete in the whole series, so feel free to disregard what I have to say.

I'm a little puzzled as to why a drop in filter costs 0.25 points (gains maybe 1-2 HP) and an ECU reflash is free (gains more than that). I could swap my K&N out for a paper filter, flash my ECU, and end up faster. IMO drop in filters should be free, modifications to the intake itself should cost points.

ECU flashes should maybe cost points if you're serious about limiting costs in stock class - how much does an OFT or a day at the dyno shop cost in terms of dollars? IMO there's a balance between allowing popular "I just bought the car and I'm gonna mod it" stuff and trying to limit cost needed to run up front. I know that's not easy.

Another thing I don't see listed at all is the stock springs/aftermarket shocks combo. How many points is this worth?

I scored my stock class autocross car and it's not eligible for the stock class - aftermarket 17x7 wheels, 225 Rivals, and a K&N air filter are enough to kick me out. Maybe I'm not the target audience for your stock class, and that's fine, but it strikes me as too restrictive. Just my 2 cents.

□ 0.00 - OEM rear spoiler
□ 0.25 - Aftermarket rear spoiler (e.g. 5-axis, integrated duckbill in trunk)

In autox, the cs class allows 5axis because they are installed at the port to some cars. Also doesn't the FRS rs come with the new TRD duckbill spoiler, where would that fall.

□ 0.00 - OEM underbody panels, including Blue Edition panels

Are TRD panels also included?

Could always put the oem filter back, takes 2 minutes :)

This is a time attack series. Stock suspension is 0 points.


Sent from my iPotato

Already covered that, I think you're missing my point. This rule seems broken. A $40 mod adds points and is a smaller power gain than a $500 mod (assuming you buy an OFT or get an EcuTek tune) that doesn't cost points. Not to mention that this suddenly becomes a must-have mod as 7-10hp is pretty substantial in what is very close to a spec class.

If your goal for stock class is "as cheap and as close to stock as possible" it seems like ECU flashes and intake plumbing changes should be 0.25 points each and air filters should be free. What's to stop me from subtly swiss-cheesing an "oem" filter? At what point is it no longer an "oem" filter? Does it really matter? (No it doesn't, because the power gains are a rounding error, which is why you should just let filters be free and ignore it).

Good to hear that it's time attack, I'll see about putting an event or two on my calendar next year.

0.25 - catless front pipe

This bugs me. Puts me at 7.125 ...

The stock front pipe is not that restrictive. And I don't even have a front pipe, just a downpipe. :iono:

Either way, I'm excited for the next year on the track with you all.

A "drop in" can theoretically be no filter.

The ECU flash is free because the real gains are from the other mods, not the ECU itself. Additionally, it is, more or less, mandatory for the early cars, unless they want to keep refreshing their DI seals/injectors/engines. We don't want to penalize the guys with early builds.

□ 0.50 - Aftermarket damper with OEM springs

Stock class is called stock, because it is meant literally for stock cars with stock tires. You're more than welcome to throw on your stock rims and tires for the day and you would qualify. It's supposed to be extremely limiting.

If they're available as a factory option, then yes, they're included. (I'm actually not sure if they are)

The rules are not built around cost.

If i wanted the most advantaged car possible, I can spend 15k to run a car in stock class, and destroy everyone.

What's the point of that? Bragging rights? It's just a casual time trial series for people to have fun at, with a great sense of community, and a relatively controlled environment to learn the limits of the car with.

Then put your stock front pipe on! :D

It doesn't fit... How about making it .125 points? A header is .25 and I can't see the front pipe as being equivalent to the header.

Exactly. I know people like to be competitive, but in all seriousness just go out there and have fun guys. I already knew that I was going to track this car and mod it before I purchased it. The fact that there is a supportive community that also enjoys tracking and modding is just icing on the cake.

Personally, I wouldn't let some rules and points prevent me from doing or undoing any mods. I fully intend to enjoy my car to the best of my abilities. My talent tends to run out before the car does anyway, so while my mods may give me an obvious advantage it's only there to mask my lack of skill. I totally give out point-bys though, so don't worry about getting stuck behind me on the track. I'm the point-by-giving fucking master :thumbsup:

Emphasis is mine. Just sayin...don't blame me for reading! :)

I don't think you'll scare newcomers away if you allow drop-in filters. No one is going to completely remove their filter, that's a silly idea given the attendance profile of stock. You haven't refuted my point here at all, which is that lumping drop in filters with full intake replacements is incongruous at best.

Looks like stock for me :)

0.25 - Any aftermarket intake system or modification to OEM intake (including Filters, except TRD drop-in)
0.25 - Any aftermarket header without a catalytic converter
0.00 - Aftermarket ECU or OEM ECU reflash
-1.00 - Any street tire TW 220-300 (MPSS Tires)
0.125 - 5-7.5" width aftermarket wheels
0.50 - Aftermarket springs with OEM dampers

Free Mods!
Brake Pads, Fluid, OIL Cooler, and Torque sending data to an old cracked S3 on my dash via Bluetooth.

Put on your stock header then! Or... run less sticky tires... :p

How about making any mod thats less than a 100 bucks a free mod?


Everything looks great in the rules, but would it be possible to make them more simple?

I let one of my friends read the rules who is more of a street guy and the first thing was: wow, these are complex.

Im just trying to help.

Dont shoot the messenger.

I'm just providing honest feedback that you asked for. The point system could use a little work. Not going to make changes to my setup.

I just don't believe a catless front pipe provides the same gains as a catless header. Leaving it at that.

I don't think this is really a feedback thread. It's "here are the rules" and "no" to all suggestions.

Mike and the other 86 Cup committee members have been doing a great job going over hundreds of hours of data from our datalogger on different cars and setups to come up with the rule set. On top of that, they spend countless sleepless nights to come up with rule sets. Not everybody will be happy because it doesn't tailor your car into a specific group, but the whole point is to normalize setups. NASA does the same thing as well.

In S2k Challenge, which has been a huge success in terms of equalizing the playing field, the points were continuously refined each year. Keep in mind, S2k Challenge has had over 10 years to develop its system.

S2k Chalengers who are unhappy with the point system will write a proper evidence base argument. Sometimes the rules change. Sometimes they don't. The feedback is generous. In this case, I stay out of the rule making process. The most important thing is getting people to come out and have fun. The reality is, a stock class car can provide some competition to mod class car with the proper driving techniques. You just need to figure out how to get there. ;)

agreed

Totally agree.

Im just trying to pass along some experience from setting up the initial S2K rule set.

D

I think the rules are completely usable and should be addressed in the case where 2 or more people in the same class are close.

FWIW NorCal used the same rules for the 2014 season and going forward with the 2015 season. Not every single driver has agreed with the rules, still don't, even with the 2015 rules changing to accommodate more mods. But bottomline is the same, we're having fun. For months now, Mike has asked for feedback and he always has evidence to support the rules. Try nitpicking one section or one mod(s) and we start to get out of the realm of practical generalization. It starts to become a not-fun conversation. Is it a one-way street? I don't think so, as honest feedback/criticism are going both ways. And rules have changed to accommodate the changes to our cars.

2014 was successful for NorCal and we are looking forward to 2015. Individuals carrying that much dislike with the rules are keeping clear of this. So for the majority, we are abiding to the same rules not so much for [mods'] relative cost to its particular gain but more so to just get out there and have fun with like-cars and drivers.

Dang, a car with full bolt-ons, coilovers, 9" wheels and 245 tires have to run in limited class.

I already tried, with a "proper evidence base [sic] argument," to get them to change that. As you can see from their lack of an evidential argument in response to me, they don't seem to care.

So for "e85" I assume this follows the government regulated miniumum legal limits of 51% (use to be 68%) ethanol. If you happen to be running 50% ethanol that is not legally E85 so therefore no points correct?

http://ethanolproducer.com/articles/...-to-51-percent

This would put my supercharged BRZ with E50 in street class with coilovers but on stock rims and tires and a half point to work with.

Thanks,

We could clarify it to be any fuel that is not 91 or 100 octane pump fuel... :D

Will you be joining us this year?

Rules are still being updated.

After long consideration and a great KBBQ (thx @ImperiousRex!), the board has agreed that all drop-in OE replacement filters should be free (0 pts).

Never assume this.

Just because we don't respond on the spot doesn't mean we don't care, there's more than one way to look at your point.

It was decided on Monday night to update the rules along with a couple of other small things.
