My brother currently has a 2" riser on his 2001 Edge, but would like to go to a 3" or 4" block. We looked at it last night and it looks like the brake cable is what will restrict this. I suggested the rest of the wires be moved to the front to give him extra slack, but doesn’t look like much more is available on the brake. Any one else have a riser on their edge, and high did you go. Any suggestions?
