What is the benefit of a monotube damper design?

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

Can I adjust the spring rates with this kit?

Yes, you have the flexibility to adjust spring rates on these dampers. The initial setup is based on extensive development and testing, but you can fine-tune them to your preferences.

What is included with this coilover set?

This set includes front and rear dampers utilizing a coilover design, springs, and both front and rear top mounts. The front top mounts are camber-adjustable, and the rear top mounts are solid.
