ORIGINAL R2/M13.12.26. 40/50 & 20HP. CARS FOR SPEED. X469 X235 Y4426 When you have to prepare cars for speed merchants, I believe we ought to fit them with double shock dampers - our hydraulic, plus say Hartford's which can be easily screwed up when high speed running is anticipated. There is no help for it but that enormous damping is needed from 50 MPH. upwards, both for safe steering and comfortable riding. I rather doubt if our hydraulic dampers (good as they are) are/effective enough at the amounts we have adopted, especially for the 40/50.
