I currently have 205/45R16 wheels, and, the tires rub against the against the body and exhaust slightly. I want to lift the rear ride height by at least 3/4", but I don't know how to go about adjusting the struts. The struts I currently have are Monro-Matics, but I don't know if they are adjustable, if not is there an brand of struts that have adjustable ride height?
