Enhance the stance and handling of your BMW Z4 (G29) or Toyota Supra (A90) with AST Adjustable Lowering Springs. This system is designed specifically for models without Electronic Damping Control (Non-EDC), allowing you to customise your ride height using the factory dampers.

By using the adjusters on the original dampers, you can achieve a more aggressive, lower centre of gravity which reduces body roll and sharpens steering response. These springs are engineered to provide a significant visual upgrade while maintaining the daily driving comfort expected of a modern sports car. Every kit is 100% made in the Netherlands to ensure premium quality and long-term durability.

  • Non-EDC Specific: Engineered specifically for vehicles without Electronic Damping Control for a perfect fit with standard dampers.
  • Precision Adjustment: Set your preferred ride height using the height adjusters on the original OEM dampers.
  • Improved Handling: Lowered centre of gravity results in better cornering stability and throttle response.
  • Quality Assurance: 100% Made in The Netherlands and backed by a lifetime warranty against breaking.

Note: This product is compatible with Non-EDC models only.
