How do I adjust the ride height and rebound damping?

The coilovers allow for ride height adjustment by changing the spring perch location. Rebound damping is adjusted using the knob on the top of the damper, with 12 distinct positions available.

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

No, these AST 5100 Series coilovers are designed to use your vehicle's original equipment (OEM) top mounts. This can simplify the installation process.

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 of the shock fluid, resulting in more responsive and consistent performance.

About this part

Product Details

Already running a performance setup? This is the next piece. The AST 5100 Series STREET TCO Suspension coilovers are built for the 2002-2007 Subaru Impreza. They let you dial in your car's balance for better grip and a more predictable feel on the road.

These are monotube dampers, which means they have a larger piston for more precise control over how the shock returns after compression. This design also prevents air from mixing with the fluid, so the damping stays consistent even when things get hot. You can adjust both the rebound damping and the ride height to get the feel you want.
