To eliminate servo jaggers. Experimental Test Report. Road Test Report. A steel spring adaptation of the rubber ring which has been used with success on the 40/50 and has been standardised. It also incorporates a stronger spring between the servo plates. Satisfactorily cures servo jaggers and has run 1000 miles on 9-G-111. This cannot affect the reliability of the car.
