looking at the golf up the road with the same arches as the ones im getting, it looks like i could chop of the bit of trim coming off the front arches and use the thicker bit there, it should just sit happily agaist and slightly over the arch, as for the rear as you say ill have to wait and see, i may not even put them on as i have small bumpers and im just kinda hoping i can make it look ok without having to get the big bumpers ~:)
