Featuring inverted, upside-down shock absorber technology, these coilovers are race-proven and deliver increased strength and durability. The design improves suspension geometry under heavy lateral and braking forces, making them ideal for spirited driving on both road and track. The 5100 Series coilovers provide adjustable rebound damping via a single knob, allowing for precise tuning to match driving preferences and conditions. Constructed with high-quality materials, these coilovers offer a significant upgrade over standard twin-tube shocks, ensuring improved responsiveness and control during aggressive driving.

Designed specifically for 1995-1999 BMW M3 E36 models, these coilovers are a direct bolt-on replacement for the factory suspension. They are suitable for street, track, or performance driving, providing a versatile upgrade for enthusiasts seeking better handling and ride quality. Installation is straightforward, with all necessary mounting hardware included. The kit is engineered to maintain optimal suspension geometry and performance, making it an excellent choice for those looking to improve their vehicle’s dynamics without extensive modifications. Compatibility is limited to the specified model years and chassis, ensuring a perfect fit and reliable performance.

Overview

The 5100 Series shock absorbers for the 1995-1999 BMW M3 3.2 (E36) utilize inverted / upside down technology. The inverted design is race proven technology and produces an extremely strong damper, providing better suspension geometry under heavy lateral and braking loads as seen in a road and track environment.

The 5100 Series shock absorbers give your car a better performance than the standard twin tube design. With the 5100 Series suspension you can adjust rebound with one knob. The adjust platform allows you to adjust the ride height of your car. AST suspension shock bodies are specially designed to keep maximum stroke, even with a lower ride height.

How a Monotube design works?

Monotube design is essential for performance. The oil and nitrogen are separated by a floating piston, and allows the use of a larger piston, increasing the damper performance and sensitivity felt by the driver, all this added together produces more grip, gives more control and driver feedback from your vehicle.

What is a rebound adjustment?

Rebound controls the rate of extension of your shock absorber. By changing the rebound you can directly change the characteristics of the vehicle.
