Class.
 
Spec7 allows for very slight mods including polyurethane bushings (Suspension Techniques) and springs (TMC or Racing Beat), and requires a substitution of driver's seat for a single piece bucket. If I'm reading the rules I downloaded correctly.

SCCA Solo II Stock class does not allow for any of these mods. Street Touring, however does allow.

However the rules for Street Touring say that it's for Sedans. Would they allow a 7 in there?

Does anyone run the same car in both Spec7 and a certain class of Solo II?

I'd be fine for changing out seats or something quick. Changing springs and bushings every event is gonna be a PITA.

C. Ludwig 05-20-06 09:00 AM

The 7 would fall into STS2 which is a class for two-seaters. However, you'll need to cage the car and pull the carpet to be legal for roadracing and that will probably bump you out of STS. At that point you might be able to SMII but you'll get monkey whored as that class usually producing some very fast competition that a Spec7 prepped car isn't able to deal with. If you just want to compete there is always a class available for whatever you show up in as long as it's safe.

is there anybody that has the rule book for a 88 tII. everytime i try scca site it doesnt show on my screen. can somebody copy and paste the rules. im looking for scca it and nasa. can anybody help out. i want a triple threat road race car

C. Ludwig 05-20-06 09:42 AM

The SCCA and NASA road racing rules are posted on their respective sites. Solo rules aren't posted. You need to purchase the book.

finky 05-21-06 07:54 AM

If you prep to spec 7 rules you would be in FP but you could probably run in EP as there is an allowance for road race 7s in that class.

Black91n/a 05-21-06 02:51 PM

SCCA Solo II (autocross) rules are posted on the SCCA site.

Follow the link and click on the 2006 Solo Rules.pdf link. That'll download the entire rulebook to your computer, or you can look at the individual sections by clicking on the links below it.

still wont work on my computer just checked. can some1 post the rules on here or pm me?im looking for scca nasa it everthing for the rules on a 88 tII. thanx

Bruceman 05-21-06 08:12 PM

I believe an ITA 7 can run in CSP. Is there a big difference between Spec 7 and ITA?

finky 05-22-06 09:51 AM

I forgot that when I posted about the class. You maybe able to fit into CSP also under the Spec 7 ruleset. When C. ludwig said pull the carpet my mind went right to Prepared.

1300cc tuner: I don't know Nasa's rules but if you post up what you want to do to the car we can get you an Auto X class and tell you the rules. TIIs are in B Stock, B Street Prepared, B Prepared, E modified, or Street Mod 2.

Pele 05-22-06 10:10 AM

Basically, I want one car to fit into both Spec7 and a noob friendly autocross class.

I've only been to two autocross events. Both of them were the Mazda sponsored test drive events, "Rev It Up" and "Zoom Zoom Live"...

I want something where I won't get whored or laughed at. :p: I'll probably get that enough in Spec7

No gutting permitted? without carpet, bins, and the plastic over the rear wheels, isn't that gutted? What all do you have left? Door panels and a dash. Seems pretty gutted to me.

Does a headliner count as carpet?

No, headliner must stay. FYI, there is a difference b/t padding and plastic over the rear wheel wells (plastic must stay). There is still quite a bit of 'gutting' to be done even after the carpet, sound deadening, plastic bins and wheel well padding is removed.

PM me if you want to talk about Spec7.

1300ccTuner 05-22-06 02:35 PM

88 tII streetport standalone 720s and 1600s inj. t04b. no ps/ac. fully gutted no interior exept dash. looking at wheel sizes really doesnt matter as long as i get the traction. full suspension. if wheels too wide rolling fenders. with all that what class do you think i can run. and any suggestions on mods and classes would be great. thanx

jgrewe 05-22-06 03:45 PM

1300ccTuner, SCCA only allows turbo cars in Showroom Stock/Touring classes. None in IT, Production or GT. You can probably run in a regional class called "SPO" and get on the track. Its sort of 'run what you brung' , there are a lot of different cars that show up to run and they just need basic safety equipment. That means weld in cage, fuel cell and fire system. That will give you the right to have your butt handed to you by a guy with more money in his tranny than you have in your whole car but you'll have a ton of fun.

1300ccTuner 05-22-06 06:19 PM

no turbos? what are you guys doing in IT. pp? whats a good carb
so what class would i be in with a bridge port and a nice carb?

jgrewe: when is your next event? isnt there a daytona track day coming soon?

sctty 05-22-06 06:26 PM

IT are 'stock motors'. In the case of the rotary, stock porting. A bridge ported motor would fit in, IIRC, GT3.

jgrewe 05-22-06 06:48 PM

I think that bridgeport is a 12A in GT3, IIRC you get put in GT2 with a 13B.

We're running Sebring the first weekend in June with my shopmates car.

IT means Improved Touring, right?

It's not listed in the rulebook.

Classes listed in the 2006 Solo Rulebook I see are:
Stock
Street Touring
Street Prepared
Street Modified
Prepared
Modified

You aren't looking in the correct rulebook. The General Competition Rules (GCR) cover the requirements for classing of road racing cars. You are looking at the Solo rulebook (hint: "solo").

The GCR is available for download on the SCCA web site. There are several classes that the RX-7 runs in.

The entry level class is Improved Touring, 12A powered RX-7's run in the ITA class, 13B's in ITS. The rules for IT are fairly restrictive - you are allowed to gut the interior, exhaust is open, intake is open (with limitations), radiators and cooling are open, suspension is fairly open. You have to use the stock body and all panels. Brakes are stock, tranny is stock, diffs are anything that will fit. Forced induction cars are not allowed. Tires are DOT.

IT was designed to try and be a relatively inexpensive class. Having said that, people are spending between $20k - $50k on the top competitive cars in class.

"Spec-7" is a regional class for first gen 12A cars. Think of it as IT-light. Less mods, more stock.

The next step up is the Production class. FCs run in E-Prod. Many more mods are allowed here. Engine porting (although mild porting only IIRC) and carbs are allowed. Composit body panels are allowed. Slick tires are allowed. Here is where racing gets real expensive.

Beyond Production are the various GT classes. There are other classes like Showroom Stock (for newer cars) and Touring. The student is encouraged to read the GCR for the details on these classes :) .

What I think that the earlier poster was pointing out was that a properly built ITS class FC should also be able to run in the Solo-II CSP class.

Hope this helps,

Ah... I was looking in the Solo rulebook for what class I'd be able to fit into in Autocross. I thought Solo = Autocross...

I'd like to be able to do both Autocross and road racing.

I guess Road Racing is also called Club racing?

jgrewe 05-27-06 09:03 AM

The SCCA allows cars prepped to certain racing class rules to compete in SOLO ll. You can't combine rules and pick the ones you want from each book and create a 'hybrid'.

I'm not trying to create a hybrid.

I'm trying to build a car that fits into one class for road racing. That'd be Spec7. And I'm trying to find a class that same car will fit into for Solo.

V8Mongrel 05-27-06 09:33 AM

For SoloII, as I understand it, you will be in Street Prepared. As Spec7 is usually a derivation of IT, you can use the clause that allows IT prepared cars to compete in their respective Street Prepared class. Note that you have to use one ruleset or the other. You cannot create a hybrid of the two rules. Usually the issue is that people will buy and extra set of wider wheels and tires for Solo use as SP has no limits in that area. If you are coming in to SP through the IT clause, as I understand it, that is prohibited.

Spec7 REQUIRES one type of tire. Toyo Proxies RA-1 205-60R13 86V... No other tire is allowed. That's pretty much the widest tire you can get under the 1st gen without suspension modification of different offset wheels. So wheels are no problem... Besides, wheels are easy to swap out before an event.

I need a class in Solo that will be okay with carpet and padding removed, unrestricted suspension, but stock engine and drivetrain.

I believe porting and gearbox changes allowed in IT. I'm gonna get whored bad enough with no experience. Having the stock 100HP (Flywheel) and stock carb 1st gen up against a 200 HP street ported, Holley carbed, close ratio transmission car is just gonna make it that much worse.

jgrewe 05-27-06 09:59 AM

Exactly what V8mongrel says. And I'll add that I hope you don't count on being competetive in SP with a Spec7 prepared car. Spec7 allows less than general IT rules and SP allows more than IT in most things. An aluminum flywheel and almost "anything goes" on the outside of the engine come to mind. You'll have fun anyway and at local events people will talk about you behind your back,"Oooo, he races on real tracks, I wish I was him...." Or something like that :rlaugh: :rlaugh:

No porting or gearbox changes in IT. You get into Prepared rules in SOLO then and you can run a GT car there. Full tube frame and all!

OK, you are missing the point here. You CANNOT swap wheels. In order to run as an SP car, you must run 100% as a Spec7.

That would be Prepared however if your car is a logbooked and legal Spec7, you can run in Street Prepared. Why? Cause they will kick your ass anyway.

You believe wrong. Read the rule books. Porting is allowed, but is very, very limited so if you are thinking of a race motor, that isn't what you will see in IT. Rotary porting is even more restrictive, IIRC. Gearbox must be factory. If you have never done autocross before, you are going to get your ass whipped anyway, so quite worrying about the damn car and get some seat time.

If you don't have a real (aka with a logbook) Spec7, then you will run Prepared. If you do, you will be Street Prepared.

jgrewe 05-27-06 02:16 PM

As stated above just go out and drive whatever you have then worry about what class you want to end up in. THEY WILL TAKE YOUR MONEY IF YOU SHOW UP WITH A CAR AND WANT TO RUN. You can run your car in Prepared if you want even if its stock.(but not the other way around) If nobody else is there in Prepared you will win.
You aren't going to find the perfect class that allows everything YOU want to do, or have done, to your car. You can only do what the rules allow or you get bumped to the next higher prep level. That happens in any kind of racing.

You aren't going to get out 2nd gear auto-xing usually so save that $5000 you were going to spend on the dog ring race tranny.

Nope. Stock in both. Limited porting is allowed in the Production classes. I assume that you are talking about porting the irons or the housings. "Port Matching" is allowed for the first 1-inch length of the intake and exhaust runners, but nothing beyond that and no polishing is allowed.

Pele,
What is your goal? Do you intend on being competitive in road racing and autocrossing or just want to drive fast and have fun? What is your budget?

I mainly want to have fun and drive fast legally... But being competitive wouldn't hurt. I don't expect to get anywhere for the first couple seasons, but I'd like to be able to be taken seriously on the track rather than some kid who's just out to fuck around.

My budget is whatever I need... I bought the RX-7 for $250... It needs shocks, springs, tires, and an e-brake cable... I'll buy those things. It needed a roll bar. I already bought that... Still looking for the rest of the cage.

I'll spend a couple hundred here, a couple hundred there...

Okay, I get it. That's all I needed.

What kinda info does a logbook have to contain?

V8Mongrel 05-29-06 06:14 AM

The logbook is the official record of inspection for your car. Consider it like the equivilant of the state inspection and registration for your race car, all rolled into one.

So when your car gets teched in at the track, they actually GIVE you something... Good to know...

So what'd make a good logbook? 3 ring binder? I assume they give your insepction results on standard 8.5x11 letter paper.

Would it be a good idea to keep receipts for parts in the logbook or would that create clutter? I assume that the insepctors can tell that I've replaced brake pads or wheel cylinders recently... Perhaps to prove origin though.

Does anything other go into the logbook? Why would one keep old inspections that are invalid an superceeded by new ones?

jgrewe 05-29-06 12:12 PM

Do not show up for a race and expect to get a logbook there. An inspection for a log book is more than they want to handle at tech at a race. Logbooks come in a couple sizes, its just a little booklet that you put all the info about your car including a couple pictures.

A log book inspection happens only after you have all of the safety equipment installed in your car; cage,fire bottle, harness, window net etc.
They will stamp a number in the cage and write it in the logbook.

You need to get a hold of somebody locally that will do it for you and answer questions.

RacerX7fb 05-29-06 04:17 PM

Pele,
If simply having fun driving fast is the goal, yes you already have autocrossed which anyone can and should do, but for driving faster on a track why not just sign up for HPDE?
http://www.nasaracing.net/hpde.htm Run what ya brung :bigthumb:
Later on after gathering more skill and $$$ then step up to wheel to wheel racing.

I thought you had to class for that. I saw some spec7's at Hyperfest when I last went...

sctty 05-30-06 04:02 PM

NASA HPDE (and Summit Point's FATTs) are for any street cars that pass basic pre event safety tech (not obviously broken or spewing fluid). Washington DC region Spec7 guys are tracktime junkies and will take it however they can get it (Hyperfest included).

Julian 05-30-06 05:43 PM

We run our Spec7 car in CSP under the IT clause, and only for fun, carb debugging and miscellaneous check outs.

IT Cluase in Solo II rules:

"Cars listed as eligible in and prepared to the current national
Improved Touring rules are permitted to compete in their respective
Street Prepared classes. Neither Street Prepared nor Improved
Touring cars are permitted to interchange preparation rules.
Improved Touring cars may use tires which are eligible under
current IT rules even if they are not eligible in Street Prepared." ...that means it is autocrossed in a configuration legal under IT.

We have taken that to mean as-is in Spec 7 trim, which leaves a lot on the table performance wise. The SP guys can run ultra wide wheels, fancy shocks, camber plates, light flywheels etc. The IT cars, fancy shocks, camber plates, coilovers, modified rear suspensions .. major allowance area of IT is basically fit suspension to original body mounting points. Gray are of Spec7 car is wheel size; Spec limits or open IT limits .. in Texas we run 13 x 7's which is good enough in stock body.

Only reason to run a race prepped car in Solo is for fun, National competitiveness .. unlikely!

Julian 05-30-06 05:51 PM

Just know what you want out of it and be happy when you achieve that. Get seat time and as much instruction as you can. Remember in SP some guys are willing and have spent $100,000 in car prep. They have also spent alot behind the scenes on self prep.
