The AST 5100 Series Coilovers F&R Top Mounts for the BMW 3 Series E36 (1995-1999) Touring model are high-performance shock absorbers featuring inverted, upside-down technology. Designed for enhanced durability and strength, these coilovers utilize race-proven inverted damper design to improve suspension geometry under heavy lateral and braking forces encountered during spirited driving or track use. The 5100 Series delivers superior handling and stability compared to standard twin-tube shocks, with adjustable rebound control accessible via a single knob, allowing for customized ride tuning. Constructed with high-quality materials, these coilovers are engineered to provide improved responsiveness, reduced body roll, and better overall suspension performance.

Specifically tailored for 1995-1999 BMW 3 Series E36 Touring models, these coilovers are compatible with vehicles equipped with the appropriate chassis and suspension setup. They serve as direct replacements for stock components, offering a significant upgrade for street, track, or spirited driving applications. The kit includes coilover shocks and top mounts, ensuring a straightforward bolt-on installation. Suitable for enthusiasts seeking enhanced handling, these coilovers are ideal for performance-oriented driving, track days, or aggressive street use, providing a combination of durability, adjustability, and improved suspension control.

Overview

The 5100 Series shock absorbers for the 1995-1999 BMW 3 Series 320i Touring (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.
