Stabilizer Bar: Description and Operation

4290 Stabilizer, 911 Carrera (997)

The stabilizers' setup in diameter and strength is designed to match the vehicle's weight and driving dynamics.

Basic chassis: Tube 18.5x2.5 mm.
PASM chassis: Tube 18.5x2.5 mm.
Sports chassis (-20 mm): Tube 19.6x2.6 mm.

The relocation of the stabilizer attachment points from the suspension strut to the wheel carrier has increased the transmission ratio of the stabilizer. The stabilizer responds more directly as a result, which more effectively reduces the tendency of the vehicle to tilt when cornering.
