It shouldn't be too hard... I ran the 225's on the back a couple times
(and Daddio experimented with it for a while). For me, that was with
AR24's shaved to 34mm offset. It _just barely_ rubbed the trailing arm
thingy.
For 225's on AR24's, I'd say you'd want 25 to 30mm offset to clear the
inside (not sure on the outside). Since the wheels you're buying are 7"
wide vs. 6", you'd need to convert the 30mm to the backspace (distance of
hub face to inside of wheel), then get that same backspace on the K1s.
Or just call Ross Atwell and copy his setup. :-)
