I asked a similar question about a year ago. On rutted highways, my car will, sometimes violently, shift left to right. Wider tires just grip the road better than narrow tires causing them to follow road imperfections. I havent found a solution for it... Never tried adjusting my camber though.

I am. A local Firestone place aligned my car to a toe of .02 and it fixed it. The spec is I think .12 to -.12 . Is was at .10 . The tolerance they say is allowable is too loose. Make them set it perfect.

Also running too high or too low of an air pressure will make it pull (to low) and dart (tramlin)(to high). The mfg spec is 30 psi.

A friend of mine with an 03 Cobra was having the same problem. He took it to the same dealership last Saturday. He had it at another dealership twice and the weeks before and they could not get it to drive right. (He doesn't think they aligned the IRS in the rear.) They spent 2 hours adjusting it but they got it right on the numbers. He said it drives perfect now. His quote was "I am proud of my car again."

Same problem here, we have a section of Interstate here that has deep grooves and it's a real pain to drive on, people prolly think I'm drunk.
