Featuring inverted, upside-down shock absorber technology, these coilovers are race-proven and deliver superior strength and durability compared to standard twin-tube designs. The 5100 Series provides improved suspension geometry under heavy lateral and braking loads, making them ideal for spirited driving on both street and track. Constructed with high-quality materials, these coilovers offer precise damping control and adjustable ride height, allowing for tailored suspension tuning to suit various driving conditions and preferences.

Designed specifically for 1998-2000 Subaru Impreza models with a 2.0L turbo engine and 5x100 bolt pattern, these coilovers are a direct bolt-on upgrade for the stock suspension.

Overview

The 5100 Series shock absorbers for the 1998-2000 Subaru Impreza WRX 2.0 GT Turbo 4WD (GC/GF PCD 5x100) 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.
