GOSHAWK FRAME AND WIDENING OF TRACK. In fitting 4-wheel brakes to this chassis it is intended to widen the track 2", partly on account of the 4-wheel brakes, and partly to provide sufficient clearance for semi-balloon tyres. This then becomes the usual large car standard of 56". The rear end and main portion of the frame width can be 1" wider than at present. R.{Sir Henry Royce} X.5380 X.4565 X.5940 | ||
