Featuring inverted/upside-down shock absorber technology, these coilovers are race-proven and deliver superior strength and durability. The design improves suspension geometry under heavy lateral and braking forces, making them ideal for spirited driving on both road and track. The 5100 Series offers adjustable rebound damping with a single knob, allowing precise tuning for various driving conditions. Constructed with high-quality materials, these coilovers provide improved ride quality, reduced body roll, and enhanced cornering capabilities, making them a significant upgrade over standard twin-tube shocks.

Designed specifically for 2007-2010 Honda Civic Type R 2.0 Vtec (FD2), these coilovers are a direct bolt-on replacement for the factory suspension. They are suitable for street, track, and performance driving applications, offering adjustable ride height and damping for customized setup.

Overview

The 5100 Series shock absorbers for the 2007-2010 Honda Civic Type R 2.0 Vtec (FD2) 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.
