    mike,

    your rear cage braces have a full "X" so you do not NEED a diagonal in the main hoop, (GCR, 9.1.4.B.2.a) though it is certainly something to think about, particularly as you look for mounting points for the shoulder belts and RH net.

    regarding cage legality for classes - there are some obvious things like the tabs welded between the cage and chassis at points outside of the IT-allowed 8 attachment points + seat mountings (2 front down tubes, 2 main hoop feet, 2 rear main hoop braces, 2 int-intrusion bars in the footwells - seat mounts are open so long as they are for the seat, yours look OK). the door sil bar is a bit worisome for easy conversion to IT legality. luckily, the car will fit into STL and should be tolerable there. very likely you can keep your cam, too (I didn't look for the specs, but 0.425" lift max in STL, in IT it must be stock). certainly an easy button. and there are a lot of VW options if you want to up the power down the road that would be legal there as well. your car would be ~2300 lbs in STL so pick and choose your cage mods wisely to stay safe and be near min weight. you can put your battery wherever you want in any class but IT.

    you do not NEED a seat back brace if that seat is homologated to FIA 8855-1999, which it proboboly is from the look of it, and it is bolted to a rigid structure, not sliders.

    oh, and welcome, have fun!

    on edit - also, the recomended Angry sheep / Chris Childs would be a good person to discuss the STL option with - he's on the STAC which recomends rules for that class

    Just an observation. It might be fixed already.
    Good eye...I never noticed that. There are little things on the cage that aren't quite finished. Not sure why the cage builder did stuff like this but it happened. It'll be welded up fully soon enough.

    I'll look into the STL class instead of IT. I'd like to keep the cam and more power is always fun.

    I'll be putting in a diagonal for the reasons you mention.

    Seat is being changed out for a Sparco EVO2 and will still be bolted to a rigid structure.

    I think once the car comes back from my friends' workshop (seat work/wheel bearing replacement) I'll try to set up something with Chris/Angry Sheep to bring it up to him and have him help me figure out legal cage mods.

    I don't recommend that; locally, there's 5-10 times as much competition in ITB than STL.

    Faster isn't fun. More competition is.

    Come up to the track and watch some of our races before you commit.

    Very true.

    I'll be up there for the first race day for sure.

    Good point, but isn't there also a lifetime requirement on these, like a brace is require once they're 5 yrs old or something?

    according to FIA, yes. (well, it's expired, and no longer homologated unless recertified) PCA and some other orgs DO enforce the age rules by forcing the addition of a back brace or whatever as they require for non FIA seats. In SCCA this is not enforced, but we have goofy mounitng rules that change our acceptance fo the homologation. I have significant issues with the seat rules.

    I figure a seat brace is cheap insurance along with a HANS device.

    Not to dispute what Chip says, but I can say that Waterford does still monitor that rule, so if you're expecting to run it there, you will need to plan that.

    Of course, it doesn't need to be bolted to the seatback, and can take the form of u-clamps for adjustment, which can conveniently be set up to telescope if needed...

    I'm planning on running Waterford so it's a necessary item.

    I'm actually kind of OK with the seat back brace that showed up in our new car, in a "well, I suppose that's about as good as it gets if you have to run one" kind of way:
