SW20 fronts or rears will work, but are slightly different strokes and damping.
I run SW20 fronts with a 12mm spacer in a 40mm chopped strut.
If you want superlow ride height (which I think you probably do), you may as well just get the HTS with a bigger spacer, as the stroke is even shorter than the SW20 stroke.
is that seriously how much you have to space/cut things up to fit the sw20 shocks into the struts? how much different are the fronts vs the rear sw20 in this application?
surely theres a better option out there re: shock interchangability, than this???
