SCCA Solo Rules and Classes

[SYO237]

http://www.scca.com/contentpage.aspx?content=61

Stock SyTys fall into F Stock Class (FS). With certain modifications we also fall into Street Modified II (SM2) and E Street Prepared (ESP).

We are NOT eligible for: STS, STS 2, STX, STU, and SM

So what does that mean:

Stock
This class includes mass produced vehicles able to be used for normal street driving. Stock Category cars must compete in their showroom configuration with only minor modifications allowed such as aftermarket shocks, wheels, and tires. Other minor modifications are allowed as well, so please refer to the Solo Rules for details.

Street Prepared
Any and all Stock Category vehicles are eligible for Street Prepared. You're also allowed to make modifications to the suspension, ignition, intake, and exhaust to further enhance the performance of the vehicle. No internal engine modifications are allowed, but minor changes to the bodywork to accommodate larger wheels and tires are permitted. Please refer to the Solo Rules for details on the allowable modifications.

heres a bit of rules for F stock.

I raced with a group in michigan known (the ferrin group?) and they were a little looser on some of the rules...I raced my cobalt ss that day but talked to the guys running it and they said that stuff such as a tune wasn't a big problem, as long as no one was complaining about you blowing them out of the water.

I haven't decided which category im going to mod the ty to, I think im gonna start stock though, only problem would be that im running a tune (see above) and i feel im going to need a good trans cooler if im planning on driving home. I think those are 2 things I could get away with though. Im planing on doing things with my suspension such as using a stiffer front roll bar, and different shocks.

Re: SCCA Solo Rules and Classes

While I don't condone "cheating", you will find most regions will look for obvious stuff (suspension, wheels, bigger turbo, exhaust, etc...). A stock chip reprogram, torque converter, L35s, etc... will most often go unnoticed. Absolutely no region that I've seen (incl. SOLO Nationals tech) has the ability (or desire) to verify EPROM legitimacy outside of a visual inspection....and even if they did, none of them could tell the difference from an OBD1 scanner.

SOLO is still very much on the honor system (unlike club racing - esp. SM), so you will see visual inspection for safety and obvious mods, but it's not worth the time for most regions to investigate mods much more. Esp. with the lack of general knowledge on our trucks in the first place.

so where would a motor & suspension & brake changed vehicle run?

Any one of those will take you out of FS. However, ESP has limitations too, so you might be pushed into an SM or Prep class depending on the severity of the mod(s). Also, for those running FS or ESP, your biggest competition will be newer Mustangs, 4th gen F-Bodys, WRXs, and the occasional Talon AWD. Though a G35 or a BMW with a good driver will always be tough too.

Re: SCCA Solo Rules and Classes

you can change your brake linings to basically anything you want and start FS, same with shocks, and a front roll bar, as long as there isnt any modification to the body or frame to make them fit, other than the front sway bar mounting location. bushings on everything but the sway bar have to be of the same material. engine can be redone @.020, and pistions have to be of the same material.

I interpreted Mike's question to mean a truck with a C5 disc conversion kit or with F-body rear discs, etc.... for brakes. You are correct on the subtle mods though, they do allow some flex in FS.

Re: SCCA Solo Rules and Classes

actually i was referring to my truck in particular. Baer brakes (corvette basically), twin turbo LS1, coilovers up front. I assume they don't care about transmission...

Yeah, that's what I had in mind (a seriously modded truck). Trans is usually a non-issue, but a converter puts you in ESP and much more than that puts you in SM / Prep. Though, again, we can be under the radar on trans for a while. An 80E or a 9" converter will be dead giveaways though, so expect to be in SM or CP if they spot those.

Re: SCCA Solo Rules and Classes

SM is a tough class to be in for a truck. I was stuck there when I had a supercharger and there are some serious rides in that class. You can make up a lot for a lack of power with better suspension but SM cars are good on both ends.

I've run ESP in 2 different clubs over the last two years and I don't have any trouble being competitive there in my normally aspirated 2wd on dry tracks (not an issue on this forum!). You guys have more power and more traction so I think if you did have to move out of F-stock you'd still be OK.

The biggest downfall I noticed when the guys ran auto-x at the Canadian Nats a few years ago was soft suspension. Big brakes and power don't help nearly as much in auto-x as getting rid of body roll. The quick transitions and weight transfer with a soft setup is a killer.

Re: SCCA Solo Rules and Classes

Also keep in mind even though the typhoon is classified for SCCA, SUV's in general are not allowed. So somewhat a conflict.

I think our trucks Renz would take some discussion to be allowed to run, and we would be in a class I don't think we would be competive anyways.

Agreed. We have the wrong vehicles for SM on a divisional or national scale (locally, some of us might be okay).....sad, but that's just how it is. For FS and ESP, we fare much better, but unfortunately, it's difficult for us to honestly abide by the rules and remain in those 2 classes (2/3 of us would have to undo what we've done already to meet ESP requirements). As a friend put it, SyTys are in the "catch-all" class of SCCA SOLO.

The Atlanta and Buccaneer Regions have no issue with Tys, but I had a buddy in Chattanooga that had to let a steward do a "test lap" in his Ty before allowing it. Regional variances I guess.

I think a stockish (v6) truck would have a great arugement.

Dobrick and I talked recently about how it would go over if I showed up in my typhoon. We both thought it would get interesting when the hood was opened and a bit of nervous feelings would come out, pending test laps, etc.

I think it would be fun the run a stock ty is FS, be nice to be able to install a rear sway bar though. Not sure what class that 1 mod would put you in.

Not sure what class that 1 mod would put you in.

If that is the ONLY thing you change then you would be in STU if on street tires. If on less than 140 TW tires then ESP.

Re: SCCA Solo Rules and Classes

Looking back, I really shouldnt be running in FS but in ESP. With the mods I have as far as intake (a2a), chipping (code59), and exhaust alone, that should put me in ESP. Once I swap out and go with the LS1 brakes, I will definitely have to merge over to ESP.

Do caltracs or dropblocks count as suspension mods to make you fall into SM or ESP?

That's why you beat me. You were heavily modified and I was stock:rotf:

:haha: How big is your turbo and how much alky you running again? Also, whats hiding under those valve covers? Youre just jealous cause I took you out on crappy 180 treadwear tires over your DRs heh

A2A and tune would be nominal if on a stocker, IMO, but added to the already modified engine you have, yeah.....probably C Prep to be honest. But for the Shindig, we knew power wouldn't matter that much.

Lowering blocks = ESP
Caltracs = shouldn't matter, but we'd have to write the SEB to be sure, though I'm thinking they'd class them like swaybars though they're not.

By my reading, you can lower the truck using factory allowed methods (turning torsion bars down), but any other method is not allowed (Both the front and rear suspension may be adjusted through their designed range of adjustment by use of factory adjustment arrangements or by taking advantage of inherent manufacturing tolerances. However, no suspension part may be modified for the purpose of adjustment unless such modification is specifically authorized by the factory shop manual for non-competition purposes.).

Re: SCCA Solo Rules and Classes

I asked the man doing safety checks at the Shindig what class I would be running in. He chuckled and said, "Well, let's see....for starters, did your Typhoon come factory with disc brakes in the rear"? Upon my "no" reply, he said well, this is easy, you are in the ESP category. As has been mentioned, if it is a readily visible mod, it will land us in the ESP class. Really no biggie if you can drive above average
