RE GROUND CLEARANCES.

With reference to the tests of the above with standard type cars on which the frames have been made to drawing I have tested 3 of these under flat spring camber conditions and have obtained the following results as regards ground clearances.

1. With chassis 2025E minimum ground clearance, silencer snout 7".
The next least ground clearance is the beading of the undershield under flywheel 7.7"
Height of frame, front 23.9 "
" " rear 23.55 "

2. With chassis 2027, minimum ground clearance silencer snout 6.875, beading of undershield under flywheel 7.75"
Height of frame, front 23.75"
" " rear 23.55"

3. With chassis 2028, minimum ground clearance silencer snout 6.9" beading of undershield under flywheel 7.875"
Height of frame, front 23.75 "
" " rear 23.55"
