Road King Suspension - is it ok to have the rear lower than the front?

I have a 2007 Road King. A few years ago, through a local HD dealership, I lowered the front and back by 2". I'm 5'7" so this gave me good foot grounding. The down side is that the front visually looks too low and is a bit more stiff of a ride. Would it cause performance issues if I left the rear low, but took the front back up to stock height?
