Rhino is right, you can't move the strut out
with the wheel, the strut is the limiting factor,
moving it out will widen, but travel will not
change, as well as the spring rate will be too
low, the stock spring at ~450 is way too weak,
needs to be increased about 100 Lbs/inch outward
movement, I have looked at this for several years,
I can see no easy way to increase the travel or
width with the stock stuff
