The first thing I noticed, other than sitting lower, was a bit of a bounce on concrete roads. However, I do not notice the bounce as much now. The car does handle better. The scrapping of the front lip occurs more often, as one would expect, but as I have become more careful on taking driveway at a greater angle, it is not too much worse. I would like to go a little lower, but the scraping would really become a problem.
Good luck!
