The AST 5100 Series Coilovers for the Honda Civic MB1 (94-00) are high-performance suspension components designed to enhance handling and ride quality. Featuring non-inverted monotube shock absorbers, these coilovers utilize advanced technology to deliver superior damping performance compared to standard twin-tube designs. The monotube construction separates gas pressure with a floating piston, effectively preventing cavitation and aeration within the oil chamber. Rebound adjustment is easily accessible via a single knob, allowing precise tuning for various driving conditions. The adjustable platform provides versatility for street and track use, ensuring optimal stability and responsiveness. Built with durable materials, these coilovers are engineered for consistent performance and long-lasting reliability.

Designed specifically for 1994-2000 Honda Civic MB1 models equipped with a 1.6 Vtec engine, these coilovers are a direct replacement upgrade for the factory suspension. They are suitable for enthusiasts seeking improved handling, lowered stance, and customizable ride characteristics. Installation is straightforward with bolt-on fitment, and the kit includes shock absorbers with adjustable rebound features. These coilovers are ideal for street driving, spirited canyon runs, or track days, providing a balance of comfort and performance. Compatibility with other suspension components is recommended to ensure optimal setup, and they are engineered to meet the demands of performance-oriented drivers.

Overview

The 5100 Series shock absorbers for the 1994-2000 Honda Civic 1.6 Vtec (MB1) utilize non-inverted / high performance monotube technology. In the past, these were known as the 4100 series. Monotube design shocks absorbers give your car a better performance than the standard twin tube design, the gas pressure is separated by a floating piston, and eliminates cavitation and airation within the oil chamber.

The 5100 Series shocks allow rebound adjustment with one knob. The adjust platform allows the user 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.
