What is the main benefit of a monotube shock absorber design?

Monotube dampers use a large piston to control rebound damping more precisely. This design prevents aeration and foaming, resulting in more responsive valving and consistent performance.

How do I adjust the coilovers?

You can adjust both the rebound damping and the ride height. The rebound has 12 distinct positions, allowing you to fine-tune the return stroke of the dampers to your preference.

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

No, these coilovers are designed to use your car's original OEM top mounts. This simplifies installation and helps maintain factory fitment.
