Default Tuning 101

Roll Center: I read the closer the roll center is to the center of gravity the less roll the car will have. The center of gravity in touring cars is above the roll center. So by raising the roll center the car should roll less.

I asked factory guys this question and got different answers.
For example:

Carpet: Low roll center car will stay flatter through the turns.

Asphalt: High roll center car will lean more.

I also got reverse responses.

Calling all experts for reponses

You are correct in you statement. The distance between the roll center and the center of gravity is called the roll moment. The larger the roll moment, the more a chassis has a tendancy to tranfer weight in the opposite direction of the acceleration.
