so the tubeframe construction will become a good business opportunity in rallying, right? dallara can start building tubeframes to sell to anyone, for example. good

can other brands (illmor, cosworth, judd...?) start building 1.6l turbo engines to sell or these 'rally2' engines are restricted to some homologated road models? im asking because idk how that works. theres no infos out there, sure, but some of you usually have more infos than what i can find on articles
