Depends mate. I've got a lowered hgt (which has slightly wider arches than standard) and have just put 18's on it today and they fit no problems and don't rub, so 17's shouldn't be a problem.
nope no rolling needed.im on 17s with a 40mm drop and i can have a full car with an install and it dont scrub. only thing i have to watch with it having abarth skirts on is the floor
