Sir,
I don't have Helm.. Checked with a dealer, who looked up the "standard," and stated it was 5.80" between the tire and the fender. Both that and the bottom end of the 33" measurement put the bumpstop within about a quarter inch of the lower control arm, which can't be right... Hence, "lost." I am inclined to agree with what you say about "where I want," I would be grateful if someone could quote Helm, or let me know what minimum distance I need to have from the bumstop. I am assuming that I don't want that thing banging on the control arm every time I go over a hill...

Semper Fidelis,

Don
