Ok Tiger, here's where I'm at now but I have yet to test it. The rear shock is 325mm eye to eye and I have a 2.8mm shim for a total of 328mm length. The front has the racetech setup with the new top out/bottom out set up, and I cut the pastic spring guide (preload collar) down as per the instrctions. (8cm?) now my length from top of the bottom clamp to the center of the axle is 49.5cm fully extended. Practice is tomorrow so I'll see how it feels.
