The front can be raised slightly by replacing the MMC steering bearings with Mulfab bearings. A quarter to half an inch.
and with an unchanged rear end that means only 1/8 to 1/4 inch in the middle or 3mm to 6mm in real units! That wont solve the problem.
You do realise, Sir Percy, that if you copied the habits of J Bonnington-Jagsworth and attacked the bridge at speed you likely wouldnt have grounded. Courage mon brave!
