Do all 48 f1's have a coil mounted to the top of the leaf springs for added suspension? My front end sits higher than the rear and I got looking at it and it seems that there is a coil spring rigged in a weird way under each side of the front end. I would think if it would be a ridability thing there would be one on the back as well. Looks like there held in place with muffler clamps. Any thoughts?
