I bent the mounting leg forward till it matched the angle of the hooks on the front support. This did two things for me. It lowered the rack to just above the fender eliminating that wasted space between fender and rack and also moved the rack back I’m guessing 1.5 inches. That was all I needed in my case to get enough heal space. Look at the black parts in the photo. The rest are add on supports for other reasons.
This photo shows how close the rack is to fender. Lower the rack the better IMO.
