i fitted a vtr kit on my old vsx, pritty simple, apart from the front and rear archs. (vsx beeing a flat arch) the rear archs will need cutting out to make the round-ish. (hold up a vtr rear arch plastic over the standard back arch and you will see what needs cutting out)
fronts are simlair. vtr front wings have cut outs so the plastic archs can be fitted. ( but the wings can be bashed in with a hammer and the plastic archs stuck on over the top) thats what i did
the front and rear bumpers are a straight swap, but you will have no front toe eye!
door trims basicially just clip on, need abit of sticking iirc
side skirts will need sticking on
and spoiler can be stuck on.
i used tigerseal to stick all my kit on with.
