Mine has really changed in that I now have to slow WAY down when going over speed bumps, railroad tracks, etc. It's sometimes strange because it often feels like if I go over the railroad tracks a little faster, it feels smoother. Any risk of tearing something up underneath?

Also, the looks are endless. Just tonight was on my way home from eating with some friends, and after I passed a guy in a Tahoe and we both came to the light, he made an effort to stop next to me and I could see him lean down to see who was in that beautiful car. Also, competitiveness from others seems to go way up.
