I-beam suspension

A suspension which uses an I-beam. The wheels on opposite sides of the vehicle are linked by a solid member, usually an I-beam but sometimes a tube. This minimizes the pieces needed for the suspension, but weighs slightly more, so is seldom used on high-performance vehicles. It was most common on older car front suspensions, but is now most commonly used on the rear of front-wheel-drive vehicles. See also twin I-beam suspension
