The Weissach axle (pronounced 'Vice-' as in 'advice' and '-ach' with guttural 'ch') is a rear suspension arrangement first used in the Porsche 928 (1978) and echoed in subsequent production models. The fully developed version was used in a Porsche 993 (911) in 1994. The goal of the Weissach axle was to eliminate lift-off oversteer by allowing the rear suspension to adjust itself during cornering manoeuvres and handle both longitudinal and lateral forces.[1]
