How do I adjust the rebound on these coilovers?

You can adjust the rebound using the knob on the damper. There are 12 distinct positions, each offering a different feel. This lets you tailor the suspension's return to extension for your specific driving needs.

What is the benefit of a monotube damper design?

Monotube dampers use a larger piston, which gives better control over rebound damping adjustments. They also prevent aeration and foaming, resulting in more responsive valving and consistent performance.

Can I adjust the camber with these coilovers?

Yes, the front top mounts included with this kit are camber-adjustable. This allows you to modify your wheel alignment geometry to improve front-end grip.
