Featuring inverted, upside-down damper technology, these coilovers are race-proven and deliver superior strength and durability compared to standard twin-tube designs. The 5100 Series shock absorbers improve suspension geometry under heavy lateral and braking loads, making them ideal for both street and track use. The adjustable rebound feature allows for precise tuning via a single knob, enabling drivers to customize ride quality and handling characteristics for various driving conditions. Constructed with high-quality materials, these coilovers provide improved damping performance and long-lasting reliability, ensuring optimal performance in demanding environments.

Designed to fit 1989 Porsche 944 models with a 2.7-liter engine (Type 2), these coilovers are a direct upgrade for stock suspension components. They are suitable for enthusiasts seeking enhanced cornering, reduced body roll, and improved overall ride control. Installation is straightforward, with bolt-on compatibility for the specified vehicle year and model. The kit includes the coilover units, with no additional components required for installation. These coilovers are perfect for street driving, track days, or spirited driving, offering adjustable damping to suit a variety of performance needs and driving styles.

Overview

The 5100 Series shock absorbers for the 1989 Porsche 944 2.7 (Type 2) 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.
