Speiro, Difficult.. cus its like solid metal.
Ive given the job to my bodyshop bloke when he does a few more bits.. mainly because its a swine, and I want a proper neat job doing - with it all being sealed, etc.. I tried, and its very difficult, and when you do get it out, its all very messy! I figured hed be able to do it all properly.
Craig, 172 wheels offset are right in the arch.. so you might not have a problem.. my guess is, when ya 35mm down.. go round a corner, hit a bump.. and itll scrape, but because of the offset being well different, it wont.
