I believe that KW is bounded by German regulations to keep the main springs secured in position at suspension full droop at all TÜV-approved ride heights. Hence the helper springs.

Good luck!
Is it possible to swap from 60 mm to 2.25" ID springs on KWs (lower spring seat/collars, helpers and couplers also would need to be changed)? Now that I've switched dampers and am using 2.25" F springs I have just enough additional clearance to switch to a 10" F wheel, if needed, and still use helper springs/couplers.
