Re: 2.B.50 - Front Suspension & Rear Track. -- -- -- -- -- -- -- -- -- -- -- -- -- -- We wish to put on record that the Exp.Dept. propose to fit the B.III. stub axle and Girling brakes to the second B.50, and have suggested that we give them a new yoke piece increasing the track from 56.260 to 58.500, but not raising the car. We are doing this. It will be necessary to instruct the Production D.O. that the springs for this car only have 1.000 of negative camber under full load, not flat under full load as instructed. Although we have instructed the front wings and rear wheel arches for the raised car which we shall not get for some long while, we do/not propose to alter them because:- 1. Most probably it is too late. 2. The rear wheel arches are usually made higher than the limit to suit the domed rear wings and will therefore clear. 3. The front wings may foul on full lock full bump, but we can deal with this if trouble is encountered by sloping upwards the mudlip. The ground clearance under the Wraith III clutch pit at full load is 8.000". That of the B.III. with 6.5 x 16 wheels as drawn is 6", but on the 7.B.5. the front has been raised approx. .750 and the clearance concerned has become 6.600". The corresponding clearance under B.50 with 7 x 16 wheels is 7.500". Ev.{Ivan Evernden - coachwork} 1-33 | ||
