The AST 5200 Series Coilovers for the 1984-1991 BMW 3 Series 323i (E30) are high-performance suspension components designed for precise handling and customization. These coilovers feature 2-way adjustable shock absorbers that allow users to fine-tune compression and rebound settings independently, providing optimal control for street or track use. Built upon the technology of competition-grade 3-way adjustable shocks, the 5200 series offers quick and straightforward setup, thanks to an evolved compression adjuster inspired by the American Grand-Am series. Constructed with durable materials, these coilovers are engineered to enhance vehicle stability, cornering, and overall ride quality, making them suitable for enthusiasts seeking a versatile suspension upgrade.

Designed specifically for the E30 chassis from 1984 to 1991, these coilovers are a direct bolt-on upgrade for the BMW 3 Series 323i. They are ideal for track days, spirited driving, or improved street performance, offering adjustable ride height and damping characteristics. The kit includes the necessary shock absorbers and mounting hardware for a seamless installation. Compatibility is optimized for models with the specified chassis and engine configuration, ensuring reliable performance and durability. These coilovers provide a customizable suspension solution for drivers aiming to improve handling dynamics and vehicle responsiveness.

Overview

The 5200 Series for the 1984-1991 BMW 3 Series 323i (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.
