How come you swapped to 23mm Jack? I have the 30mm but do have size 12 dogs. I was going to buy the 50mm but they are listed as not suitable for driver. I looked at rearsets but I didn't want to go back and up but back and down. Most rearsets don't offer that as they are primarily for the race track. I have the superpole seat and the varios on now. Probably as good as it gets leg room wise for 6ft 5" on a 1098.
