A lot of people think that by installing a bumpsteer kit, and dialing it in, the car will stop swerving all over the road over uneven serfaces. While it will help a little, most of what is called tramlining actually has to do with the tire surface than the actual bump steer. Bumpsteer is most evident on the track under aggressive driving. When the suspension compresses, the toe angle changes, so that results in two things1. You end up with a different toe angle you had when you initially turned in for the corner. As the suspension compresses, the wheel usually toes out just a little bit, so little to your knowledge, the steering wheel imput does not correspond to what the front wheels are doing. That's the difference between understeer, oversteer, or staying on line.2. Not all tracks are smooth. Most of them have bumps and uneven surfaces in the middle of the corner. When you hit those bumps, suspension compresses again, changing that toe angle, and leaving the car slightly unsettled through the corner. For example, Turn 8 at WSIR is a triple digit corner. In my slow car, I enter it doing 110mph. There are a few good bumps all the way through the corner, right into the braking zone. This is the last place you want to feel unsettled. It does not really effect me that much, just because I'm running a fairly wide and sticky tire, but for someone who is on a smaller tire, might have a bigger problem.</blockquote>
