i roll fenders on the side for local car clubs, most shops(inCA) dont do this at all.. they almost always use mallets and pound your fenders in, it makes lumpy uneven work.. i have to fix these all the time.. ive done several Evo 8,9 and 10s and maybe 90 mazdas.. on the X chassis you will end up losing the little rubber sound deadening strip the runs the length of the fender.. just make sure they lift the whole car(awd) and use heats guns!! otherwise its not that hard.. Eastwood fender rollers FTW
