What is the benefit of a monotube damper design?

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

Can I adjust the spring rates on these coilovers?

Yes, the manufacturer states you have the flexibility to adjust spring rates on these dampers. The initial setup is based on their development testing, but you can fine-tune them.

What is the warranty on AST coilovers?

The manufacturer states that these dampers are rebuildable at a certified AST service center. For specific warranty details on parts and labor, please refer to the AST manufacturer's warranty documentation.
