That bracket is a clever solution (y) I'm looking into fitting Rallyflapz Miniflapz (plain universal) or ordering their Formentor Rallyflapz Shortiez kit just for flaps with the copper logo and then use a bracket like you have there. I'm not very good with these things, though :p
Easy enough didn't take the wheels off use a small ring spanner and a torx bit need to paint brakets next job when it's clean.
