The AST 5100 Series Coilovers for the Volkswagen Golf MK2/1G (1990-1992) are high-performance shock absorbers featuring inverted, upside-down technology. Designed to enhance suspension dynamics, these coilovers deliver increased strength and durability compared to standard twin-tube designs. The inverted damper construction improves suspension geometry under heavy lateral and braking forces, making them ideal for both street and track use. Built with race-proven technology, these coilovers provide superior handling, stability, and responsiveness. The adjustable rebound feature allows for fine-tuning of damping characteristics, ensuring optimal performance tailored to driving conditions and preferences.

Specifically engineered for the 1990-1992 VW Golf MK2/1G with the 2.0 16V engine, these coilovers serve as a direct upgrade or replacement for the factory suspension components. They are suitable for enthusiasts seeking improved cornering, reduced body roll, and enhanced ride quality on both daily drivers and performance-oriented setups. Installation is straightforward, with bolt-on compatibility for the specified model years. The kit includes the shock absorbers and necessary mounting hardware, providing a comprehensive suspension upgrade. These coilovers are ideal for drivers looking to maximize handling capabilities on the street or track.

Overview

The 5100 Series shock absorbers for the 1990-1992 Volkswagen Golf GTI 2.0 16V (MK2/1G) 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.
