The AST 5100 Series Coilovers for the Subaru Impreza WRX GG/GD (2005-2007) are high-performance suspension components designed to enhance handling and stability. Featuring inverted shock absorber technology, these coilovers are race-proven and deliver superior strength and durability compared to standard twin-tube designs. The inverted design improves suspension geometry under heavy lateral and braking loads, making them ideal for both street and track use. The coilovers allow for rebound adjustment, enabling precise tuning for various driving conditions. Constructed with high-quality materials, they provide improved damping performance, better control, and a more aggressive stance.

Designed specifically for 2005-2007 Subaru Impreza WRX models with a 5x114.3 bolt pattern, these coilovers are a direct bolt-on upgrade. They are suitable for enthusiasts seeking enhanced handling, whether for daily driving, spirited street use, or competitive track days. Installation involves replacing the factory shocks with these coilovers, which include adjustable components for personalized setup. Compatibility is limited to the specified model years and chassis, ensuring optimal fitment and performance. These coilovers are an excellent choice for drivers aiming to improve their vehicle’s suspension response and overall driving experience.

Overview

The 5100 Series shock absorbers for the 2005-2007 Subaru Impreza WRX 2.5 (GG/GD PCD 5x114.3) 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.
