[Bobboloo]

901 15x6 Fuchs are refered to as a deep six and were installed on 911s from 69' thru March 71'. In March of 71' Porsche went to the later style 911 15x6 flat Fuch. They differ in that the face of the later Fuch is flat in the background where they are painted black. The deep six had more depth and were curved in that area.
