Sounds like you have the insiders technical information for design and application, am I assuming correctly ? If I'm to understand what you're saying about suspension conponents between the 6 and the Fusion, then one could use lets say Strut Tower Braces, performance brakes, anti roll bars, etc. as long as it doesn't include items that involve length in the floor pan.
Suspension pieces from the 6 like springs, shocks, and swaybars will work with the Fusion, but I'm not so sure about brakes. EBC lists different part #s for the Fusion and the 6. Also, they changed the brakes in the 6 for the 2006 model year, so they MAY be the same now.
Personally I'm gonna use EBC rotors and pads since they list part #s specifically for the Fusion.
