Im wondering if all S2000 have this problem ( or it's not a problem ).......
Whenever Im breaking, for example the road is not perfect and theres a feet wide and 3 inch deep hole, when my right-front tire goes over the hole at the same time im breaking, somewhere around 15-20mph. then my steering wheel will tilt to the right pretty hard by it self. same thing on the left side.

Also when im changing lane and the same time making a suddent stop ( this is when im trying to cut my friend off at the speed of 60mph and was breaking pretty hard cause theres a red light in front of me ) my steering wheel will also tilt to the whatever side of the lane im changing in to. in this situation, the tilting strength of my steering wheel is a lot more stronger. Anyone know why?? is this normal?? do you guys have this problem??

 

sounds like tramlining...normal for cars with wide tires.

I agree, only 'normal' thing imo that could cause this. I never felt it, not over bumps when breaking or whatever, just that wide tires have a tendency to follow the part of the road that is the most used and therefore more worn... Strange thing is that you have it when breaking!? Something wrong with the car?

 

tire pressure? check it....it happened to me once and my passenger side tire was deflated a bit.

 

Completely normal with wide tires
