Description

Enhance your BMW Z4’s handling with the AST 5100 Street Series Coilovers, a perfect choice for everyday driving and road performance. Designed to optimize grip and stability, these coilovers allow you to control rebound and set the ride height precisely, providing a balanced and comfortable ride. Featuring springs compatible with OEM top mounts, they are tailored for specific vehicle fitment, ensuring seamless installation and reliable performance. The AST design incorporates a monotube structure for front dampers, maintaining a divorced setup for the rear to emulate OEM characteristics, resulting in a more comfortable yet responsive suspension system.
Each coilover includes fixed spring rates in the rear, established through extensive development and testing to meet high-performance standards. You can fine-tune the damping response by adjusting the rebound knob, which offers 12 distinct positions for personalized feedback and handling. This adjustability enables you to achieve a road balance that suits your driving style, whether for daily commuting or spirited driving. The monotube dampers utilize a large piston, which enhances the control of rebound damping and eliminates aeration or foaming, leading to more precise and responsive valving. The high-pressure design ensures optimal performance across various driving conditions, while the rebuildable nature of these dampers allows for maintenance and repairs at certified AST service centers.
Designed for easy customization, these inverted, 1-way adjustable coilovers provide both ride height adjustment and rebound control, delivering a tailored driving experience. The front coilover design ensures a sporty yet comfortable feel, while the rear setup maintains OEM-like characteristics for improved ride quality. Whether you’re upgrading for better handling or customizing your vehicle for specific driving preferences, the AST 5100 Street Series Coilovers are a reliable and high-performance choice that combines quality engineering with precise adjustability.
