Lowering the ride height?

[madmanjustice]

Oi! I have lost of questions today...

Has anyone experimented with lowering the ride height of the enduros? On the front I know I can loosen the the clamps on the triple trees and slide the forks up but I'm looking for a way to lower the rear. It looks like my choices would be either a shorter shock or adding a shackle of some kind to relocate the top of the current shock.

Just for reference this bike will be street only and not taken offroad.

I'm also considering adding spacers to the forks to firm up the springs a little more for street riding as well.
