Description
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.
- 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.
- Material: Cold-wound High-Tensile Steel
- Finish: Corrosion-resistant Powder Coat
- Design: Vehicle-specific progressive rates
- Origin: Made in the Netherlands
- 2x Front AST Lowering Springs
- 2x Rear AST Lowering Springs
- Installation Documentation
Note: Professional installation and a comprehensive wheel alignment are highly recommended after fitting to ensure optimal tyre wear and handling performance.
