Engineer}6/AP.13.9.37 WRAITH STEERING We wish to be able to try a caster angle of ½° on the front pivots of Wraith in conjunction with lower tyre pressures. Will you please detail yoke pieces to give the above angle. We believe that for experimental purposes the existing forging will modify. Rm{William Robotham - Chief Engineer}/FJH.{Fred J.
