Stabilizer Bars

Stabilizer Bars on the Front and Rear Axles

Body roll is built up over the vehicle's longitudinal axis as a result of the centrifugal force at the center of gravity. This force causes the vehicle body to lean towards the outside wheels while cornering and quickly draws the vehicle closer to the limits of driving dynamics. The tilt angle of the body and the increased wheel load is counteracted by the use of stabilizer bars.




When cornering, the wheel on the outside of the corner compresses the spring, and the inner wheel extends the spring which causes the the stabilizer bar to turn (twist).




The forces on the mounting points of the stabilizer bar generate a torque that counteracts the body angle providing better load distribution on both wheels on the same axle.

The suspension is firmer with a solid stabilizer bar. The disadvantage is that when you are driving straight ahead during a one-sided compression (bounce), this transmits a "copying" effect through the suspension, which reduces comfort.
