spastic rear suspension

So 72bluNblu... I should rebuild my entire suspension is what you're saying.

Well, based on your own argument that hitting things makes you a better driver you might want to look into it. After all, you've hit more things in "the last few years" than I have in the last 20. So, by your logic you should be an amazing driver. I would think at some point you'd be such a good driver that you'd stop hitting things, so maybe your suspension is what's holding you back.
