all ya need are 2 things a sawzall and duct tape.

really lowering with a front spring kit and shorter rear shocks is not that complicated. If you follow the directions (guessing the spring kit comes with them) and take your time and are the least bit mechanicly inclined you should be able to do it. Or if you have a mechaincly inclined friend to help you out.
Kind of hard to see here because of the bags but I lowered Wendys bike 2" in the back and left the front stock.
It handles very well and doesn't scape except in the very rare case when the rear tip of the exhaust scraped. I lowered the front 2" after lowering the rear and it scraped too easily so I put it back.
