Alignment and road crown

bluekn8286 · 12-15-2012, 11:54 PM

Hey there alignment experts, I wanted to know how much road crown really affects alignment? How much pull is considered normal? Are e90/e92 M3s really sensitive to road crowning in general? I have had my car aligned a few times and each time it comes out fine and the techs say the car drives straight. For the most part, the car feels stable, but I do feel a pull to the right on the freeway and around town; according to what others have said, I suspect this to be normal road crown pulling. Am I just being paranoid?

Thanks everyone

If you are talking about tramlining, check you tyre pressure. In my case it was the culprit. I had put wider tyres in the E46 M3 - in fact it was CSL wheels on a normal M3 - and it was tramlining. Can't remembers whether increasing or decreasing fix it. No such issues with the E92 to date.
