^Oh yea, GFroce is tits… but its hard to get into, as they make a living by making full-on race cars (full tube chassis track only type ish).
IIRC Vitez or antonicelli did Newmans E30 cage, and it looks well done.
NYI generally is no where near that strict. Maybe next year when Bob isn’t running operations anymore, who knows…
Also, I’d be surprised if JEGs or the other popular places make a prefab’d kit for a Bimmer. :shrug:
