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.


Key Features

  • Optimised Centre of Gravity: Lowers the vehicle to improve both visual appeal and high-speed stability.
  • Superior Handling: Progressively wound rates ensure sharper steering response and reduced body roll.
  • OEM Integration: Specifically engineered to function with factory dampers and electronic suspension modes.
  • Premium Manufacturing: 100% Made in the Netherlands using high-tensile chrome-silicon steel.
  • Durability Guaranteed: Finished in a signature powder coating for maximum corrosion resistance and backed by a lifetime warranty against breakage.
