That's what I thought Steve but I don't know enough about it, found a forum that boys where running only 10mm on track cars, mine is road mainly, I would like to see a couple inch to be honest but I don't know enough about it, I have 55mm off travel before my wheels hit arches, so have added correct size bump stops so it can only travel 50 ish. Don't think it will travel that far tho to be honest, if it doesn't at least I could gain droop.
