Not really going to help you - but I had an alignment done at a local place (Geico shop) after smashing a pothole and completely wrecking my alignment. My car literally jumped a foot off the ground and landed hard. Tires and rim were perfectly intact. No damage whatsoever.
Ever since I did the alignment -my goodness, my car feels awesome. It's inexplicable. I guess after 5 years of driving it must have misaligned or something. I've since put on 4 brand new tires and had each wheel high-speed balanced. I don't think my car would have felt better if it was brand new...lol
Anyway - alignments are great to do once in a blue moon. lol
