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. Rebound damping is adjusted using the knob on top of the damper, with 12 distinct positions available to change how the suspension extends.

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

No, these AST 5100 Street Coilovers are designed to work with your Fiat 500's original OEM top mounts, which simplifies the installation process.

What is the benefit of a monotube damper design?

Monotube dampers use a larger piston to control rebound damping, which allows for more precise adjustments and a more responsive feel. They also prevent aeration and foaming, ensuring consistent performance even under hard driving.

Product Details

AST uses a monotube design for these dampers. That means a larger piston inside controls the rebound damping, which helps make the adjustments more responsive. Monotube designs also prevent aeration and foaming, so the valving stays consistent even when you're pushing the car. The springs are included and designed to work with your car's original top mounts, simplifying installation.
