The AST 5100 Series Coilovers for the BMW E36 318i are high-performance shock absorbers designed to enhance handling and stability. Featuring inverted, upside-down technology, these coilovers are race-proven and deliver superior strength and durability compared to standard twin-tube designs. The inverted damper construction provides improved suspension geometry under heavy lateral and braking forces, making them ideal for spirited street driving and track use. The adjustable rebound feature allows for fine-tuning ride characteristics, ensuring optimal performance and comfort. Built with high-quality materials, these coilovers are engineered to withstand demanding driving conditions and provide consistent damping performance.

Designed specifically for the 1993-1999 BMW 3 Series E36 models, including coupe and sedan variants, these coilovers serve as a direct upgrade or replacement for factory suspension components. They are suitable for enthusiasts seeking improved handling, cornering, and ride quality on both street and track environments. Installation is typically bolt-on, with no major modifications required. The kit includes shock absorbers with adjustable rebound settings, enabling precise suspension tuning. These coilovers are ideal for drivers looking to enhance their vehicle’s performance and suspension response during aggressive driving or competitive events.

Overview

The 5100 Series shock absorbers for the 1993-1999 BMW 3 Series 318i Coupe/Sedan (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.
