The AST 5100 Series Coilovers for the Lotus Elise S3 (2011 and newer) are high-performance suspension components designed to enhance handling and ride quality. Featuring non-inverted monotube shock absorbers, these coilovers utilize advanced high-performance technology to deliver superior damping compared to traditional 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 available via a single knob, allowing precise tuning for various driving conditions. The adjustable platform provides further customization, making these coilovers suitable for both street and track use. Built with durable materials, they are engineered to improve stability, cornering, and overall suspension response.

Designed for 2011 and newer Lotus Elise S3 models, these coilovers are a direct bolt-on upgrade that replaces factory components. They are intended for enthusiasts seeking improved handling performance and ride customization. The kit includes the shock absorbers with rebound adjustment knobs and the necessary mounting hardware for installation. These coilovers are ideal for street driving, track days, or spirited driving, offering a balance of comfort and performance. Proper fitment is specific to the Lotus Elise S3, and no additional modifications are typically required for installation. They provide a reliable upgrade for drivers aiming to optimize their vehicle’s suspension dynamics.

Overview

The 5100 Series shock absorbers for the 2011+ Lotus Elise (S3) 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.
