I have a 2014 Si Coupe, and I'm looking to get either Eibach Sportlines or H&R Springs. Will pretty much any mechanical shop do spring installation? I would be more looking to take it to a known shop (i.e. Pepboys, a Honda dealership, or something similar). Any general idea about how much they usually charge? Or labor hours, since I know every shop varies with price per hour. Also, how will I know if I need front & rear camber kits. Some people say you need them, some say you don't. If I do, any recommendations on what camber kit to get?
