Default Need classing Help - i'm lost in the rulebook

My Wife has a 2007 WRX TR - we've added or changed the following parts as follows:

front and rear sway bars
endlinks
lowering springs
KYB GR-2 adjustable struts
front subframe brace
front and rear strut tower braces
Catless turboback exhaust
VF39 turbo
Front mount intercooler
AOS
tuning - non AP

I was thinking SM, but i'm not sure if I'm looking at the right class. I did ask at our last event of the year yesterday and they weren't super sure. so I figured i'd ask the people most likely will be. thanks for the input.

You're legal enough for SM. The subframe brace and front mount intercooler are likely done in illegal to the rule book ways, but no one is going to care at the local level. If someone does for some reason the completely legal class for you would be XP.

and that's way i asked, i read sm rules the intake was unrestricted, but is that only applicable to pre turbo parts? And for the sub-frame brace i read the part about sub-frame connectors but i understood it as fore and aft, not lateral where the concern

You can always just go in mod and not worry about it. SM pax time isnít really much of anything anyway.

Unless youíre very competitive to other cars in SM , most are not going to scrutinize to that level. Or youíre going to go to nationals.

SM engine rules are "it's open with the exception that the short block case has to come from the OEM foundry". So intake, exhaust, head castings, guts inside the case, turbo, all open. The driveline is also completely open so you can run a 2 speed power glide if you want and a Ford 8.8 rear end.

The crash structure is sacred though, and specific bracing is also forbidden because of specific cars that it REALLY helps.

Awesome, thanks for the help! She's going to run novice for the first couple, but if she gets told to pick a class, now I know

And I can always unbolt the chassis brace, I don't know that she would care either way

STU is currently a real national class with rules, Street Touring Ultra

Some regions use the designation STO for Street Tire Open.

We have SU - Street Unlimited --- it's our fun class, but if you take season points you can't run in it the following year, you have to pick a class. I started there and ended up moving to STH in my 18 this year. once she gets the boot from novice this is where she's going for now, but SM looks to be where the car should be at. thanks again everyone

you will be SM or BSP if I remember I've only been to two events this years. most of my time this year has been maintence, or with family. so I haven't gone out to many events.
