20 HP. SIDE SPARE WHEEL CARRIER. X5600

With reference to the double arm carrier on the car which has just gone to France, we thought that it was too flexible. This is the reason for holding up the signing of the standardisation sheet.

As the tubes are only slightly less than the Phantom tubes we are not sure that the whole flexibility is in the tubes. Could you investigate this, as it is possible some reinforcement inside the frame would be better than increasing the tubes. If you could tell us where the flexibility is we will send you a revised scheme.
