Weissach axle

The Weissach axle is a rear suspension arrangement first used in 1978 in the Porsche 928 and echoed in subsequent production models. The goal of the initial Weissach axle design was to eliminate lift-off oversteer by allowing the rear suspension to adjust itself during cornering manoeuvres and handle both longitudinal and lateral forces. A fully developed version was used in the Porsche 911 (993).

It is named after the town of Weissach (German pronunciation: [ˈvaɪsaːx]), where a Porsche research and development centre is based. "Weissach" is also a backronym for Winkel einstellende, selbst stabilisierende Ausgleichs-Charakteristik (angle-adjusting, self-stabilizing equalization characteristic).
