The AST 5200 Series Coilovers for the 1984-1991 BMW 3 Series 320i (E30) are high-performance suspension components designed for precise handling and customization. These 2-way adjustable shock absorbers allow users to fine-tune compression and rebound settings independently, providing a tailored ride experience for street or track use. Built upon the technology of competition-grade 3-way adjustable shocks, they feature an advanced compression adjuster inspired by designs used in the American Grand-Am series. The shock absorbers are engineered for quick and straightforward setup, enabling drivers to optimize suspension performance with ease. Constructed with durable materials, these coilovers deliver consistent damping and improved stability, making them ideal for enthusiasts seeking enhanced control and responsiveness.

Designed specifically for the 1984-1991 BMW E30 3 Series, these coilovers are a direct replacement for factory shocks, offering a significant upgrade in handling dynamics. They are suitable for street, track, or spirited driving, providing adjustable ride height and damping characteristics to suit various driving conditions. Installation is straightforward for those familiar with suspension upgrades, and the kit includes the necessary shock absorbers with adjustable features. Compatibility is limited to the specified model years and chassis, ensuring optimal fitment and performance. These coilovers are perfect for drivers aiming to improve their vehicle’s cornering, stability, and overall driving experience.

Overview

The 5200 Series for the 1984-1991 BMW 3 Series 320i (E30) are 2-way adjustable shock absorbers which are based upon competition 3-way adjustable shock absorbers. The 5200 shock absorbers are adjustable in compression and rebound.

The design of the compression adjuster is an evolution of the compression adjuster we provided for the American Grand-Am series for the last few years. The 5200 shock absorbers were designed to achieve a quick and easy set up, allowing separate adjustment of compression and rebound.

The 5200 Series AST uses an external canister. Throughout testing and competitions, the 5200 has been praised for its performance and capabilities, surpassing other major, more expensive brands and setting a new standard of 2 way damper. Its no surprise that the 5200 is fast becoming a favorite damper amongst race teams and track day enthusiasts world wide.
