Hi every one, I recently fitted challenge springs to a 355 to be used for track days. All the parts were supplied from a Ferrari dealer and assembled and installed as per the drawings. One thing that occurred was the spacer between the front front springs, seems to be rubbing on the webbing that strengthens the front turrets, when under load. Has any one else experienced this or is there a mod that needed to be done to eliminate this that I've missed? Many thanks in advance.
