We've run ladderbars on the street for years. I think the cornering issues are due to no sway bars and the skinnies up front. There is a pretty good lean to the cars when you corner and the ladder bars rattle a bunch (upper coilover mounts mostly). Usually have ground clearance issues with the front crossmember mounts. The last one, we had to cut the lower part of the mounting holes off when we got it adjusted so it wouldnt drag when we crossed a speedbump or pulled in a driveway or something. All in all, I love ladderbars, they just look good. I had a friend that put the clamp on ones with the stock leafspring setup on a Torino one time, Didnt work very well but it looked cool...
