I'm also adding PLM header + Greddy Emanage before the season hits.

So my question...I am almost certain I'd fall into STR class for AutoX per: https://dk1xgl0d43mu1.cloudfront.net...pdf?1484176131

My only concern is that my rear interior around the roll bar/trunk is stripped . The front has full interior. Do I need to replace all of this to be able to run? I'm sure the locals wouldn't care but maybe regionals and I'm almost sure nationals. I am only asking because I couldn't find the words in that document I posted. This will mainly be an open track day vehicle but I'd like to definitely do a little AutoX with my friends as well...you know for fun. :)

Cheers.

Test pipe is not allowed in any ST class

Balls. Yeah I re-read that and showed something about cat needing to be a certain distance from the original. High flow cat I assume is okay....

What about the interior though? That's the largest challenge.

You probably alright at any regional event, going to nationals, you are going to want to put all the plastic back in trimmed to fit around the roll bar. You can leave the bulkhead out with the roll hoops but I'm not sure you can leave out the stock seat belts. Some other STR guys can probably confirm.

I assumed this was the case, but hoped it wasn't. :'(

I'd have to buy the plastics from someone because mine did not come with them. ZZZ

You should be able to find those plastic pieces fairly cheap from someone building a similar car/track car. Cutting is a bit tedious but can be made to look well.

I'll be on the lookout I guess. I think it's worth putting back in anyway....this car is LOUD on the highway.

Local events probably won't give you too many problems, but yes, you will need a cat (or HFC), you will need to put the plastics back in.

what pieces do you need. looking to go full track car. within the next to weeks interiors coming out.

I sent in a request several months ago for clarification around S2k rollbars, given that the rear bulkhead needs to be replaced to properly position a harness bar. It's finally worked its way to the SEB agenda, and so there should be a bulletin in Fastrack about it soon. Hopefully that will provide some clarify on exactly what's allowed. I've got some unofficial early info that these installs will be possible, but I don't know exactly what will need to be retained.

I've got stock uncut roll hoops and rear plastics sitting in my shed. If you were local I'd just give them to you.

check your fenders and liners.

While it's not considered a lot of work to get these wheels to fit from a real-world usable standpoint, it is when you start looking at what is considered an "STR-legal" fender with a "roll". There aren't very many people running those wheels in STR for that reason. If they fit, you can bet a whole lot more people would be running them for STR since the price is right, and they're super light.

STR offsets for a 17x9 wheel are more reasonably in the +55 to +63 range.

They fit just fine; zero rubbing by some kind of magic. So you're saying my fenders might be rolled too much? It is indeed very tight in there.

They should just let us do whatever we want after this happened last year:

Awesome news. I look forward to hearing about that.

I need everything rear of the seats. The plastics w/ the back pieces w/ hooks, side pieces, etc etc. Basically everything. Seats forward everything is there.

OR I guess the other option is to just go to street prepared and run Hoosiers LOL

Check my post:

Technically not having the plastics bumps you all the way into SSM like me if you read the rules strictly. Nothing is allowed unless it is explicitly written. Hopefully Nate above gets some more clarification. I wish they could allow for this with a car that is essentially falling within the spirit of the rules of the class. Plastics are plastics and other than a slight weight advantage, if somebody wants to remove them (especially for safety equipment) why not just let them and penalize them? For me, I'd happily take a 100 lb ballast hit due to not having plastics or softtop and non OE hardtop, which when you account for ballast for no softtop is really just ballast itself, just so I could run in STR. Everything else for me certainly falls within STR, and given that at the last local event I was over 1.5 seconds ahead of the STR winner...I know that even 200 lbs is not even close to 1.5 seconds on a 50 second course.

Totally agree. I think locally they will let it fly....this is Detroit after all. Dominated by Miatas, Camaros and Corvettes.

Yes. I would check the possible legality of your roll. Chances are, it shouldn't be a problem, until you start winning...

Lol well im usually in GM products so this will be my first time in a lightweight roadster.....I'm sure it will be a little brutal to start. I haven't AutoX'd in years either....all open track days/work.

Does not appear anyone else brought this up, but the brake ducts may be an issue too. They allow brake ducts, but not body modification to accommodate them. Usually they would let you tape over them though. Otherwise test pipe for sure needs to be changed. Plastics would probably be dependent on area. I took out my AC in my area and they offered to still put me in STR.

On this note, I wont be going out of my way TOO much to make this STR legal. The main purpose of the car is to be an open track day sloot. :) AutoX is kind of secondary.

So many damn rules.....pushing more and more towards Modified.

Is this an STR legal mod? Somehow I have it in my mind that it is not, but I'm not sure.

Technically no.

Would be the weeniest protest ever...

Plus, I'd say there's a reasonable argument for it under section 13.1 of the street rules:

"All repairs must comply with factory-authorized methods and procedures, or industry standard methods, as follows: If the OEM does not provide an appropriate method of repair, industry standard methods and procedures may be used. Such repairs may not result in a part or combination of parts that provides a competitive advantage (e.g., significant change to weight, suspension control, power, etc.) as compared to the standard part(s). Competitors are strongly cautioned to use this allowance to make common-sense repairs only."

Yeah that is super ticky-tacky. It provides no advantage to the car other than allowing it to function as intended.
