The AST 5100 Series Coilovers for the Mercedes-Benz C63 AMG W204 (2007-2015) are high-performance suspension components designed to enhance handling and stability. Featuring inverted, upside-down shock absorber technology, these coilovers are race-proven and deliver superior durability and strength under demanding driving conditions. The design improves suspension geometry during heavy lateral and braking loads, making them ideal for both street and track use. The coilovers provide adjustable rebound damping via a single knob, allowing for precise tuning to match driving preferences and conditions. Constructed with high-quality materials, these coilovers offer a significant upgrade over standard twin-tube shocks, ensuring improved ride quality, responsiveness, and control.

Designed specifically for 2007-2015 Mercedes-Benz C63 AMG models, these coilovers are a direct bolt-on upgrade that maintains compatibility with the vehicle’s existing suspension setup. They are suitable for enthusiasts seeking enhanced performance on the street or track, providing adjustable ride height and damping for personalized handling characteristics. Installation is straightforward for those familiar with suspension modifications, and the kit includes the necessary components for a complete upgrade. These coilovers are ideal for drivers aiming to improve cornering, reduce body roll, and achieve a more aggressive stance while maintaining ride comfort and stability.

Overview

The 5100 Series shock absorbers for the 2007-2015 Mercedes-Benz C63 AMG (W204) 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.
