Would putting back a little pre load on the sway bar help prevent the contact, or make it worse? Stiffer sway bar maybe? Does anyone make a stiffer one for us than what we have? But then you'd probably have to reinforce the chassis mounting locations. You're obviously getting faster and finding new limits. Good luck with ironing it out. I'd buy your MikeR adjustable sway bar links if your not going to use them, LOL.
