How do I adjust the compression and rebound settings?

The AST 5200 Series coilovers feature external reservoirs. You can adjust the compression damping by controlling how quickly the suspension moves inward, and rebound damping by controlling its return to extension. Each adjustment position provides distinct feedback.

What is the benefit of the inverted strut design?

The inverted strut design is used to handle heavy side loads and braking forces. This makes the suspension more robust for performance driving scenarios where these forces are significant.

Do I need to purchase separate top mounts for installation?

No, this kit includes camber-adjustable front top mounts and solid rear top mounts where applicable. These mounts help optimize front-end grip and provide a solid connection for the rear suspension.
