Off and ready for some magic anyone confirm that the rear spring is 100-165lbs it's what I thought anyways .
I'd say no, as most later ones are done in nm and would only be one weight reading. As it used to be 400 lb to compress one inch to measure car springs. Not sure what sag figure they would use to give correct weight figure ?
Hey Wedgie!, 59 refers to the spring diameter the first number 100 is the rate ie 100N/mm the second is the Spring free length ie 165mm
