The AST 5100 Series Coilovers for the Honda Civic 1.5 16V EG8 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 for precise tuning to match driving preferences and conditions. The adjustable platform provides additional customization, making these coilovers suitable for both street and track use. Built with durable materials, they are engineered to withstand demanding driving environments while maintaining consistent performance.

Designed to fit 1991-1995 Honda Civic models with a 1.5 16V engine (EG8), these coilovers serve as a direct upgrade or replacement for factory suspension components. They are ideal for enthusiasts seeking improved handling, lowered stance, and enhanced stability during spirited driving or racing. Installation is straightforward, with bolt-on compatibility for the specified vehicle years and models. The kit includes the coilover units with rebound adjustment features, ensuring comprehensive suspension tuning. Suitable for street, track, or performance applications, these coilovers provide a reliable upgrade to optimize your Honda Civic’s suspension dynamics.

Overview

The 5100 Series shock absorbers for the 1991-1995 Honda Civic 1.5 16V (EG8) 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.
