AST 5200 Coilovers are 2-Way adjustable coilovers that come with their own adjustable top mounts, and are ideal for fast road, track day and motorsport usage.

The key features of AST 5200 Coilovers for BMW E90/E92 M3 are:

• 2-Way adjustable (independently adjustable with 11 clicks of bump and 12 clicks rebound)

• Remote reservoirs for superior performance and heat displacement

• AST Monotube technology

• Gas-pressurised for improved performance

• Inverted strut design for improved lateral and longitudinal g-force control

• Includes AST camber plates

• True rear coilover design for maximum on-track performance

PLEASE NOTE - vehicles fitted with BMW Electronic Damper Control (EDC) will require a delete kit to prevent error codes from occurring.

More information

The AST inverted damper system is a race-inspired design that gives the damper far more strength and resistance to high g-forces generated by fast driving. This design helps to retain the suspension geometry of the car during the cornering, braking and acceleration phases, ensuring consistent cornering performance.

The ride-height adjustment platform allows you to adjust the ride height of your car whilst retaining the maximum stroke of the damper.

AST's Monotube technology improves the damper's performance and efficiency by separating the damper oil and nitrogen gas inside the damper with a floating piston. This floating piston design, combined with the use of high-pressure nitrogen, helps to eliminate cavitation around the piston.

The larger piston and lack of cavitation increases the damper performance and the sensitivity of the dampers felt by the driver. All of this combines to produce more grip, increased control and driver feedback.

The independent 2-way adjustability of the 5200 Series gives you far more control over the damping characteristics of your BMW.
