sod brackets, best way which i did was to cover the wing in clingfilm, stuff some fibreglass filler up on the top edge, push it into position on the car, hold it there for 5-10 mins, take it off, there you have a perfect match for the wing, this should then be stuck on with trim adheasive and screwed in from the back of the wing with some small self tappers.

u should have got a fitting kit with thie wide arch kit, however i didnt,and i was sent one after i phoned up,unless u make your own brackets

how do i fit the wide arch front because there are no fittings with it ?
