SCCA defers to the local state rules on 'licencing'. So if she has a permit she can drive, but has to follow the same restrictions as on the public roads (e.g. 'Requires an Adult in the car'). Clear this with the event's particular management early though, they often don't know this national rule allowance and might balk at you wanting to be in the car.

Looks like this one fell through the cracks.

It looks like they classed the Z/28 in AS in the March FasTrack, so yeah, with 200+ treadware tires you're in AS (actually 140+ treadware for the remainder of the year)

With the new +/-1" wheel diameter rule this year in the street (stock) classes, you are allowed to run an inch smaller than stock, however you have to retain the stock width to be legal. That being said, I doubt people will complain locally if you compete in S1 (SS, AS, BS, and FS cars combined) with wider wheels, as long as you don't win ;)

With the new classing rules, I still register as "Novice", "S2" would only be when I move out of novice class?

What should the numbers on the car read (505 N)? If I was not novice would it still be "505 RTR"? Cheers.

Neil Bhamb wrote:THANK you. So I have numbers that say "505 RTR". I should throw away the ones that say "RTR" and instead get two sets of "NOV" and then later "S2"? And that'll last a couple seasons (assuming no mods to cars?)

Rick Brown wrote: You didn't mention what tires you are using, that determines CS or CSR. I'm guessing a higher than 140 treadwear since you ran RTR last year, so CS. NOV plus your car number is not enough, we (Timing & Scoring) want your base class also (not everyone working the timing computer is a classing expert). So your class letters should really be NOV CS, then CS2 when you move out of Novice. We assume what is on your car is correct and if the computer says different, we change it to match your car. In NOV especially, the base class can be anything and we have no way of knowing what has or has not been done to a given car.

Jeff Stuart wrote:In my experience, many people at every event don't display their index class when they're running NOV (and in many cases the same applies to people running other index classes, though to a lesser extent). The index class is already in the computer from registration, right? When I work the computer, all I have to do is enter the car number since they're unique at local events.

That being said, I always show my index class, but I thought it was more of an optional or informational thing, not a requirement. That's fine if it's a requirement, I just didn't realize it was.

Yeah it all works great until it doesn't. When people switch cars or incorrectly classify themselves its a lot easier to 'notice' when they run thier class id on the car. Which means less post event fixes.

"Class" is set by the SCCA nationally, my Subaru BRZ is "CS" = "C street class"; the next class up being "CSR" = C Street-R class.

"Novice" is a local/regional class, and during my time in this class, it effectively supercedes my base class for competitive rankings. When I choose to step out of Novice class, then my SCCA, nationally determined, "CS" class takes over right?

So what is the two in CS2 and why does it apply after I drop Novice? Does it have something to do with the way the PAX/RTP indexes are used to adjust times?

But to answer your question we break the Stock class cars on street tires into three groups, While not an entirely applicable description, S1 is the High HP classes: SS,AS,BS, and S2 is the lower HP classes: CS, DS, ES, leaving the low HP FWD cars in S3: GS,HS.

Guy Walker wrote:Hmm... I think of it as car classes (SS, AS, BS, CS, etc.) and competition classes (PAX, S1, S2, S3, etc.)... sometimes the two overlap. SCCA sets up the car classes and the region sets up competition classes where drivers of cars compete in either a single car class or multiple car classes (through car class indexing). Is it that simple or am I missing something?

What we put on the car helps timing and scoring get things right in the computer when we mess up during registration.

Neil Bhamb wrote:Brilliant. So I would be ranked against everyone in S2 (CS, DS & ES); but each car would have a PAX index applied to it that depends on the car class (i.e. an ES car with a slower time would be adjusted higher). Individual model of car does not change your PAX index right, just the car class?

Looks good up to the last sentence/question. The term PAX is the same as what I call the car class index. The individual model of car puts the car into a car class which has a PAX/car class index. So, in effect, the individual model of car determines your PAX/car class index.

I, personally, use the term car class index instead of PAX because car class index makes more sense to me... especially since PAX is the name of a catchall competition class where drivers of cars in any car class can compete against each other. Having one term, PAX, mean two different things is just confusing to me. Call me simple... I like car class index.

Second: Is the 2014/15 Camaro Z/28 running AS with 200+ treadwear? Can I run 18" wheels that are 1/2" wider than stock (stock is 19x11 + 19x11.5) I have some 18x11 + 18x12's.

Third: How would I class a Chevrolet Volt with the engine disabled (bolted plug visible in the exhaust pipe, removable for street use). Have both 17x7's and 18x8's. Can it run in Electric with the 18's? What is the treadwear limit?

OR, if I just want to Run-What-You-Brung with 3800lb domestic cars, do I just go Time Only, or is there a catchall class?

Fourth: Am I on the right board? My user and password did not work, so I had to make a new one. I used to post on http://www.solo2.com.
