when i first got my busa i had them install fully adjustable lowering links and asked them to lower the seat height 1"... dont know how far that lowered the bike because i need the seat height down cause i got short legs... I had ridden the bike for a week while i waited for the lowering links to come in and after they lowered just the rear, it felt like i was plowing through the corners. After i bought reaper risers and lowered the front, the handling was much much better. my .02 is lower the front and rear at the same time cause it will affect the handling if you dont.
