thanks, i think i understand all that but my next main concern with this system would be that in tightening up the rear end too much youre only going to influence the car to lift up on two wheels and increase risk of rolling. but up to the point where the tires do lift i agree you would have better handeling. i wont be using a rear sway bar on my car for this reason i placed the initial query for a friend whos looking at doing it to his road car. i would love to see some pictures of this set up if that is possible, thanks heaps, Michael
