If you intend going to a 350z-uk.com meet and you want to be different, keep the OEM aerial, don't modify the engine bay with a JWT popcharger or Kinetix Plenum, keep running on the standard UK18's (with Bridgestone's), keep the standard zorst, standard grill, standard lip, standard skirts, standard spoiler and don't put any rear spats on. Oh, and lastly don't put any real or fake carbon fibre anywhere.
Do that and you're guaranteed to be unique and it won't cost you a penny!
