Default Talk to me about the NASA/SCCA rulebook

I have a 2013 BRZ that I've raced a few season in the local region SSCA AX in D Prepared.

As of right now, the car has:
Full interior strip, only thing left is two front seats, 2 door card, 2 sunvisors and a custom stack to hold radio/AC controls.

Eccentric upper rear control arm bushings for camber adjustment.

Front eccentric bolts for camber adjustment.

SS brake lines.

Brake MC brace.

Replacement front control arm braces (aluminium vs. stock steel).

Replacement steering rack bushings.

Performance air intake.

Tune.

I'm preparing to finish prepping it for hillclimbs, road racing and more AX (it was supposed to get caged two winters ago, life had other plans) and I've reached a point where I'm concerned with where my plans are going to leave me classed.

Broadly what I want to do is:

Full DOM cage, through the firewall tied into the front suspension and tied to the rear for maximum chassis stiffening. Kirkey fixed seats and 6 point harness.

Full motor build or motor swap, at a minimum I'm looking at a element tunining built FA20 with a supercharger on top shooting for 345-375 wheel. If I go the swap route, who knows, but a more reliable 375+ would be the goal.

Wilwood bbk front and rear.

Motion Control suspension.

17 or 18" wheels running the widest rubber possible in AX trim (315 for 17", 345 for 18", Hoosier A7) Varied sizing for hillclimb and road racing/HPDE

Radiator relocation to trunk with primary airflow to the radiator coming from the underside of the car.

Battery relocation

CF roof skin

Additional lightening and weight relocation where possible. including a bar to protect the engine welded between the front frame rails and then a fascia holding replacement of the bumper beam. Obviously no airbags.

Possibly New transmission/rear differential or a different gearset installed in trans.

Special attention paid to aero, flat bottom, diffuser, aero moving through the hood, splitters, dive planes and chassis mounted rear wing.

My budget for the build is somewhere between 50-70K over the next few years. There's no hurry here and most all of the non-welding/machining work I can do myself.

Still street legal-ish/registered/inspected in PA, if only just.

My concern is that some of my plans may leave me with nowhere to really run the car and well outside of the rulebooks of NASA particularly. I'm almost certain SCCA is right out other than going to XP and never running pro-solo/national level events.

So educate me, destroy my dreams and otherwise inform me of what I'm about here. I can always add a dash of sorts back in with some cloth and shellac/epoxy and I'm totally willing to do that because from what I've seen most series require a dash of sorts.

I don't have a particularly series in mind, I more want to build the best racing 86 that's still street legal that I can and then race it where it fits. But if, things like the cage running to the front suspension puts in a class with cars that have build budgets far above mine that I'll never be able to keep up with, I'd rather make a small adjustment to my plans than try to undo it later.

You're already in DP and some of what you want to do is beyond XP even. If you want to build the car the way you have in mind to enjoy and don't want to build to a rule set then do it. Building to a rule set would require some though and a specific build path. I think the car could be competitive in XP actually, although you'll want more power.

AutoX isn't the main focus of the car regardless, just something I have done with it and will continue to do at least at a regional level.

Ok, your post made it sound like you were concerned about where you were classed based on mods, but if autox isn't the main focus then just do what you want. All of that stuff will likely leave you in XP with a few things beyond that maybe since I'm not super familiar with XP rules. But, again, if your focus is to just build what you want and then track it and local autox, do what you want.

I'm concerned about classing for NASA/SCCA road racing stuff.

Unless you want to build to a specific class, make sure your region has some people in SCCA's ITE and run in that group. ITE is IT saftey, DOT tires, the rest is free. Ive been on track with crazy Porche's, ex IMSA Corvette's as well as super low budget yet fun (read fast as hell) bmw's, honda / acura's etc that don't want to be held to a tight rule set. Only down side is ITE is regional only, so if your local track does a Majors event, you wont be able to run that event.

Nasa's super touring is much easier to class in hp/weight groups where as SCCA basically throws you all together to fight it out, however I have no actual experience other than comparing rule books.

If you modified yourself out of a class, no worries! NASA has a Super Unlimited class! Pass safety and run what ever you want as long as it has fenders.
