How do I adjust the ride height and rebound on these coilovers?

Ride height is adjusted by threading the lower spring perch up or down on the shock body. The rebound damping is adjusted using the knob on top of the damper, with 12 distinct positions to choose from.

Do I need to buy new top mounts for these coilovers?

No, these coilovers are designed to work with your vehicle's original OEM top mounts. This helps simplify installation and maintain a comfortable ride.

What is the benefit of a monotube damper design?

Monotube dampers use a larger piston, which allows for more precise control over rebound damping. They also prevent aeration and foaming, ensuring the valving remains responsive even under hard use.

Product Details

AST makes these 5100 Series Street Coilovers for the 2011-2014 BMW 5 Series F11. If you're looking for a better balance between daily driving comfort and road grip, these coilovers are a solid option. They let you control your car's rebound and ride height to maximize tire contact with the road.

This kit uses a monotube damper design, which means a larger piston can be used to control the rebound damping. This design also prevents aeration and foaming, so the valving stays responsive. The front dampers are a coilover setup, while the rear maintains a divorced setup like the factory setup, contributing to a more comfortable ride. The kit includes springs and is made to work with your car's original top mounts. You get vehicle-specific, fixed spring rates for the rear.
