So after much internet searching it turns out its not a simple arch roll on the widetrack, a couple of people have removed the rear arch extensions and shaved out whats left of the arch and replaced the arch extensions, something I don't really have the skills to do.
So first question is is anyone willing to take this one with me or could recommend a suitable body shop that would (somewhere people have used before)
Or..
I have also looked into getting rear camber plates and maybe be able to give it enough camber that there would not be the need to touch the arches, anyone use these at all, people talk about tyre wear etc?

Thanks
Simon
