Saddle Height Adjustments
Q: How do I shim my saddles to match my guitar's radius?
A: The standard radii on Floyd Rose six string systems are 10" with the preinstalled shim and 12" without. To change the radius on a tremolo, it is recommended that you shim the individual saddles to match the preferred radius on your guitar. A small piece of copper or aluminum tape is an inexpensive and simple way to raise the saddle height.
A standard radius gauge can be used to measure your neck and bridge's radius: http://www.stewmac.com/shop/Tools/Special_tools_for_Neck,_fingerboard/Radius_Gauges.html
