question for ya, what kinda car is it? RWD or FWD? cuase if your relocating it for racing reason then if its FWD it wont do anything but hurt your times. if its purely for look then go for it. the RWD cars need it cause if tranfers weight on to the rear wheels and help with traction. in a fwd car you would want the wieght on the front wheels. its a lil more indepth than that but that is the short anwser
