REAR SPRINGS - B.50 & Wraith 60. It has been decided that 7" static deflection springs are best for these cars. Will By/HEB{H. Biraben} prepare the necessary springs drawings for 56" springs, and add to the LOP. Both ends should be suitable for threaded pins and the springs for both cars will be the same except for the load. B.III also has 7" static deflection rear springs. Rm{William Robotham - Chief Engineer}/AFM.{Anthony F. Martindale} | ||
