Silly thought ... Could you all make up some adjustable end-links?? I'd like the ones with a spring on the link.

This setup will let the car roll a bit , until the spring binds. Once that happens the car takes a set and digs in. By tweaking the preload on the spring , you can tune the bar to your taste.
