| B III & B 50 STEERING GEOMETRY ERRORS FULL BUMP APPROX. NORMAL HEIGHT FULL REBOUND ANGULAR DEVIATION OF ROAD WHEEL - DEGREES. ① 7 B V WITH C.S. TUBES LOWERED 0.500 AT CENTRE. ② 7 B V WITH C.S. TUBES LOWERED 0.250 AT CENTRE. ③ ESTIMATED 7 B V AS ORIGINALLY BUILT. ④ B 50 CHASSIS AS ORIGINALLY BUILT BUT NOT YET RUN ON ROAD. | ||
