The AST 5100 Series Coilovers for the Lotus Elise S1 (96-01) are high-performance suspension components designed to enhance handling and ride quality. Featuring non-inverted monotube technology, these shocks provide superior damping performance compared to traditional twin-tube designs. The monotube construction utilizes a floating piston to separate gas pressure from oil, eliminating cavitation and aeration for consistent response. The coilovers include rebound adjustment via a single knob, allowing precise tuning to suit various driving conditions. Built with durable materials, these shocks are engineered for improved stability, cornering, and overall driving dynamics, making them an ideal upgrade for enthusiasts seeking enhanced performance.

Designed specifically for 1996-2001 Lotus Elise S1 models, these coilovers are compatible with vehicles equipped with the original chassis and suspension setup. They serve as direct replacements or performance upgrades for stock shocks, suitable for street, track, or spirited driving. Installation is straightforward, with the coilovers designed for bolt-on fitment. The kit includes the shock absorbers and necessary mounting hardware, ensuring a complete upgrade. These coilovers are perfect for drivers looking to improve handling precision and ride customization on their Elise.

Overview

The 5100 Series shock absorbers for the 1996-2001 Lotus Elise (S1) 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.
