BENSPORT ROAD SPRINGS. We find that the rating of the Bensport front road springs is too high. We think that the stiffer type Peregrine is the correct rating for Bensport. Will you therefore please order for us a pair of front springs to the following specification - Free camber - 2.750 Laden camber - Flat. Max. Deflection - 4.500" Spring poundage at laden camber 650 lbs.+ Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} | ||
