Look, we obviously don't like each other.
But please please please prioritize stuff. Before buying fancy steering wheels or vented hoods you don't need, sort stuff that needs sorting first like the tappety engine, any rust/welding needed, safety equipment (that includes a proper roll cage with a proper harness bar, seat, helmet, fire extinguisher) and then you can move to upgrading it for track use. You've done the first and most important thing already, stripped it, so now you can start adding upper and lower strut braces along with any engine mods you may want to do. Don't spend money pointlessly on parts you really don't need like that bonnet. You're better off spending it on track driving lessons or a trackday different than brands hatch or even a set of trackday tyres.
