OE style booted ball joints and bonded rubber bushings maintain factory ride, handling and noise, vibration, & harshness (NVH) parameters. Audi's unique multi-link suspension creates a 'Virtual' SAI. The factory does not publish a specification for caster, but SPC recommends 5deg to 6deg of caster as a preferred angle for tracking and return to center on these cars.
