AST Lowering Springs- Audi S4 / A4 (S4)

Aggressive Stance. Enhanced Dynamics.

Transform your vehicle’s profile and performance with AST Lowering Springs. Engineered for drivers who demand a more aggressive aesthetic without sacrificing ride quality, these springs provide a significant reduction in ride height while working in perfect harmony with your factory dampers.

By lowering the centre of gravity, AST springs reduce body roll during cornering and nose-dive under heavy braking, resulting in a more stable and communicative driving experience. Developed through decades of motorsport expertise, each spring is cold-wound to prevent sagging over time and is designed to integrate seamlessly with modern electronic suspension systems.
