I have an 03, but the principle is the same. I am lowered 1.25" in the front and a little over 2" in the rear, and extended almost 6". Here's pics of my back tire so you can see I am getting over just about as much as you:
Now the only problem I have, other than speed bumps, is I've found that under extreme cornering that I've scraped the fairings a little bit on both sides. To counter that effect, I could change my riding style, and lean off the bike a little so the bike doesn't have to lean over as far. My point is, a stretched and lowered bike can be ridden hard through the twisties, particularly within the legal limits of the given roads.
