The rolled arches blend in and are not really noticeable.
Hi Mark I have the same arch rolling tool to do the arches on my Son,s Subaru Impreza track day car but I have'nt used it yet so not sure how it will work. My front and rear arches were rolled a long time ago as mine is 35mm lower than standard and was essential to avoid any contact between the tyres and arches.They were done the old school way as I don't think there were any tools around to do it yourself. You like things to be done right on your car and I would rather get a bodyshop to do it as you don't want any damage to the paintwork.
