How do I adjust the rebound damping on these coilovers?

You can adjust the rebound damping using the knob on the damper. There are 12 distinct positions, each offering a different level of control over how the suspension returns to its extended state.

What is the benefit of a monotube damper design?

Monotube dampers use a large piston for better control of rebound damping. This design prevents aeration and foaming, which results in more responsive valving compared to twin-tube designs.

Can these coilovers be rebuilt if they wear out?

Yes, these AST dampers are rebuildable. If any issues arise, they can be serviced and repaired at a certified AST service center.
