im thinking about doing some auto-x and after a bit of research i think i know what class it belongs in but just for fun maby you guys can help conferm it.

what class would you put my car in??






this was befor ths e-fan, new 12a, and coilovers.

Kentetsu

Okay, you're gonna have to list your mods if you want to know for sure. However:

1. Blowthrough turbo? I'm I seeing what I think I'm seeing? If so, off to SSM with you!
2. Camber plates put you in CSP
3. Is the motor ported? SSM

But really, what you need to do is go to the SCCA website and look over the rules. They are pretty clear on what you can/can't do. Beautiful car btw.

Hey Kentetsu, I see that next year GSL-SEs will be classed in STR instead of STS and need to compete with S2000s. Any tips on how to be competitive with the Hondas?

Rogue_Wulff

Technically speaking, the GSL/ GSL-SE were never legal in STS due to the LSD. It's the LSD that bumps those, and the GXL FC's to STR. Remove the LSD, and they would then be legal for STS, since that's the only reason they were bumped to STR. ST/STS specifically bans any form of LSD, and has all along.


As for the OP's question. SSM, EM or possibly XP. Not sure about the boost allowance for prepared. Go the scca.com and download the solo rules. They will tell you what is permitted in each class. If it isn't specifically allowed, then it's not legal for that class.

Factory standard LSDs are allowed in ST and STS 14.10 section K

Rogue_Wulff

Viscous only. From the 2011 SCCA SOLO rules: (Section 14.10)
The GSL/GSL-SE/GXL LSD units are NOT viscous, instead they are clutch type, and therefore not allowed.

Clutch types are a subset of viscous according to SAE.

In anycase, the classing change is a done deal now. I'd like to know how to adapt without moving out of ST*, or if there is no way in hell a 1st gen 7 can compete with a S2000

Rogue_Wulff

S2K's are going to be tough to compete with. They start with a rather large advantage in the tread cross section and IRS. Kinda hard to stuff a 255 under the fenders of a 1st gen RX7 and keep them apart. Doable, but not easy. Especially since most 255 width tires are also taller than what is normally found under a 1st gen.
Can an FB compete with S2K's in STR? Depends a lot on car setup and driver skill, but it's not gonna be easy.

BTW, did you know removing the OMP is not legal is street prepared? It's listed in the rules, and has been since at least 2006, but in a very well hidden location.
Appendix F (Clarifications) under Street Prepared Catagory Clarifications:
Sneaky, huh?

Kentetsu

Eh.... S2000s are just Miatas with a bad attitude. Crunchy on the outside, chewy on the inside. Altogether a tasty treat.

They taste great with salt on them!! I beat EVERY S2K that comes to my sandbox!!!

Make your car an EM car and have fun!! I plan on going EM!!

I beat an S2K at Gratten with a NA SP 13B and some poor driving. It can be done.

Hmm. I can't tow my 7 (single car garage in an apartment complex) so going EM seems not practical. Also I have the top two national STR drivers in my division as regulars so its going to be one hell of a challenge.

Kentetsu

Well, I like CSP because I can do all the cool stuff to my car I would want to do anyway (like emissions removal, suspension upgrades, carb). And, I still get to drive it to work every day.

But it sounds like you would have to spend a year "downgrading" your car before you would fit the rules.

Do you really have to trailer a EM car though? You could run a "soft" setup, not taking advantage of everything the class offers, so you could retain some driveability.

And consider yourself lucky to have good competition handy. I get some fun from the Detroit guys who are pretty serious, but we also have some local guys with hot setups who really know how to drive. If you aren't challenged, then you won't improve.

It's precisely that type of arguement that caused the SCCA to spell it out, clutch pack LSD's, as factory installed in the models specified in STR (GSL, GSL-SE, GXL and 1988 GTU), are not legal in ST/STS.
Simply put, had you gone to a National level event, and been protested over the diff, you would have lost, been disqualified and labeled as a cheater. But, there's always those willing to take that chance.
The 90-97 Miata is also allowed in STS, but they added the words "non Torsen equipped", just to insure those who were skirting the rules by using a Miata with Torsen LSD in STS know they are not in compliance. The torsen equipped Miata's also got got placed into STR, where they rightly belonged all along.......

Emissions is the big thing. Not only do they test here in CO, but they poke around the engine bay as well. I can't register it as a collector's car (no more emissions) because it would have to be a '74 or older.
