Post scca classifacation questions?

i am just getting started in scca but i have noticed that the impreza can fit into several catagories
g-stock,csp-dsp,sts,smod(with turbo?)?
any one care to elaborate on how/where our cars fit in
i was thinking that your input and where you have been clasified would be better than trying to decypher the ol rule book

If you haven't done anything to the car (besides maybe changing the tires), you belong in GStock. If you've done minor things like sway bar and intake, you belong in STS. CSP/DSP is what some people try to htrow the car into because of the rear LSD on the MY00's (IIRC), but you should really still belong in STS. SMod is (I think) deep engine work (I don't think even cams are allowed in STS), turbo, supercharger, etc, all go into this class.

If the car is 100% stock it fits into GS. Last I heard a couple of mods will bump you up into STS.

Ok, in stock form the RS is classified into GS. The stock class rules allow for some parts, like a replacement airfilter element (K&N dropin type) and front sway bar, but not rear sway bar and Rcompound tires.

In modified form you have to be careful of what you do concerning classes. STS and STR are basically the same class, except in STS you must use true 140+ treadwear street tires and in STR the tire rule is the same as stock class. Most common mods like intake, exhaust, rear swaybars, strut braces, coilover suspensions etc.. are STS/STR legal.

SM (Street Mod) is basically the wide open class. You can turbo/SC and do alot more to the car. Basically if it can be registered legally for the street where you live, its SM legal.

DSP is the street prepared class that the SCCA has recently put the RS into. There are more alowances than STS/STR, but there are many more specific rules and you cant go turbo/SC unless the car came like that from the factory.

So in short, it depends on what you have done to your car. I believe the best class for the RS is STS/STR. The single best thing you could do is to buy a rule book and join the SCCA. That way you will get SportsCar Magazine which has the monthly tech update called the FastTrack in it. The rules and language of the rules is constantly changing, so after the publication of the rule book for the year, they use the FastTrack updates to keep everyone informed of the changes. For instance, in the 2000 rule book, it would seem that the RS is still a NOC (not otherwise classified) entry to CSP, but in the July FastTrack it was offically classified into DSP.

If you are concerned about which class to run in because of the mods you have already done to your car, email me and Ill help you figure it out. magilla@olg.com
And if there is something you are considering but are unsure of the legality of it in a certain class I can help you there too.

I run GS, the mods I have done that are allowed are: cat-back exhaust, brake pads, alignment, harness, KYB AGX struts, and BF Goodrich R compound tires on a second set of RS rims. I think stock class is the way to go because with minimal mods the focus is on driving, which always have room more improvement. The second year, make the next step in STS or DSP. I just happen to like autoxing in stock classes.

Problem being that on paper the ITR is unbeatable in GS, with 195HP and 2500lb vs. our 165HP and 2800lb. It has better gear ratios too.

I agree with Eric, the best class for the Impreza RS is STS. Or street mod, if you've got the money to burn. Haven't seen someone build a DSP car yet, but the Fiat X1/9 sure is light (~1900-2000lb in DSP trim) even though it only can make maybe 120HP (stock is 85! with the 1.5L).

Colin - On paper the ITR might be beat the RS, but I've seen SUV-ETR kill a few of them in GS with nothing but BFG auto-x tires!

Sorry, but on paper or at the autoX, in equally capable hands, with equally equipped cars(ie, they have everything that stock class alows) the ITR will eat the Impreza up in GS.

Take a look at http://www.moutons.org/sccasolo/stre...ing_rules.html and http://www.moutons.org/sccasolo/index.shtml . That first link will take you to the Street Touring rules, including a link to allowed modifications. The page also has links to the actual rules for Stock and Street Prepared. For some really good condensed descriptions of what is allowed/not allowed in Stock and Street Touring, check out the second link I listed.

Depending on where you are and what kind of club you run with, STS might not be available. I run with a non-SCCA group that uses (for the most part) SCCA rules, and we don't run any Street Touring classes.

I like running my Impreza in STS for a few reasons:

1) In GS I can't really be very competive IF the other cars are using race compound tires (hoosiers, etc) and I am not. In Colorado, the GS cars haven't invested the money in race tires yet, but they will soon.

2) I don't want to remove my intake modifications, and will have a 20mm sway bar in a week.

3) I want to learn how to drive my street tires fast, what the limits are, etc... This is the best reason to run STS.

[edit] let's spell hoosier's right

I'd vote for STS too.

Frank (Marius) and I have both been running STS, Frank is very competitive with his 160 Treadwear Kumho 712s. He keeps insisting he is a bad driver, but he still kicks my butt with only an 18mm rear bar and the Kumhos. (I run the STi V5 Struts, Springs, a whiteline bar (22mm currently), brick hard BFG all season tires with probably not enought tire pressure, and my girlfriend as a passenger)

The last auto-x we were at STS consisted of
Frank (99RS)
Me (98RS)
an E30 BMW M3 w/Eibachs and an awesome driver
Sentra SE-R
Focus ZX3 (intake, U.D Pulley)
Pontiac Grand AM (slow)

It was pretty fun, The M3 beat Frank by 1 sec or so, myself, the focus and the SE-R were 2-3 secs behind.

The last event we were at had about 4-5 ITR's running in GStock, and with Race Rubber, that's not much fun to compete against.

go STS.

Something just hit me.

I have a question about that M3 or about any M3 in STS...

Isn't the M3 considered a sports car?

STS is for non-sports car based cars, no?

i don't agree with them allowing the E30 M3 to run in STS. it is a sports car, and is classified thoroughly in A stock and C street prepared.

sounds to me as if he just wanted a win, and they let him slide. i would protest him, if it happens again.

the event officials have to be aware of the vehicle classifications when they tech. if there is any question, then consultation of the rule book is a good way to answer them. if the book does not specifically allow it, then it is illegal.

this definitely looks shady to me.

I'm pretty sure it was an E30 M3. The early 90's model with the 190-ish HP 4 banger. Kinda looks like a fancy K-car.

I think this guy (M3) usually runs in C-prepared or something like that (and usually with R compounds) but he just had street dunlops on, so entered STS. Yeah, he won, but Frank was at least in the same neighborhood.


I didnt have a problem with it I guess, plus he's a super nice guy.

Are you sure it was an M3. The M3 is not sportcar based, well, the 3 series is not sportscar based. I know a person that is building a 3 series AWD STS car, and it is using all viscous LSD (front back and center he says). But it is not an M. I think the best arguement for not allowing an M3 into STS would have to come on a LSD basis. Do the M3's (whatever MY are in question) come with a mechanical LSD or is it viscous. If it is not viscous, its not allowed into STS or STR. But SM is ok.

yes it is a legit M3. like I said above, the early 90's 4 banger version.

STS is pretty casual around these parts, and none of the tech inspectors seem to know anything about Subarus. At this past event they didnt even look under my hood, and they have never asked me about any suspension mods. It would be pretty easy to slip my car into G-Stock is I was dishonest.

was it a points or non-points event?

that seems to effect how serious the competitors are around here. (www.nrscca.com, nebraska region)

autox is all about having fun. some people forget that.

heh, that i can totally relate to. try running a street car in a race prepped class. you stand about zero chance, unless no one else shows up.

i normally run in CP, a *very* competitive class around here. incredibly specialized vehicles attend. you are allowed 16x12 inch slicks in CP...

I think a few of the old RX-7s that run around here in CSP just run insanely wide slicks. Probably almost twice the width of the original tyres. There was an older Mustang at the last event that also had absolute steamrollers on it. crazy.

that mustang would probably be a cp car.

anyways, back to scoobys!

i have yet to see one run in our region. there are about 3 of them that show up, and none of them ever race. talk about frustrating.

i don't even have one yet, and i want to challenge these guys to get out and represent. it is entirely driven by me wanting to watch them, to see how they work out there.

Question

SCCA is thinking about a complete restructure of the stock classes. So far they have 1-9, basically splitting SS, 1 & 2, and combining ES and HS into 9. Go to www.scca.org click on what's new and click the tech bulletin section. I think the 2.5RS will go into class 8. The Type R, Celica GTS and DSM will go into class 4.

Here is a direct link to the appropriate FasTrack and memo Gary is talking about.

It's near the bottom and fairly lengthy.
