What does 'double adjustable' mean?

Double-adjustable shocks allow you to adjust both the compression and rebound damping independently. This gives you a wide range of control over the suspension's response to bumps and body motion.

What spring rate should I choose?

Spring rate is a matter of personal preference and vehicle setup. A stiffer spring rate will generally improve handling, while a softer spring rate will provide a more comfortable ride. Consider your vehicle's weight, intended use, and the type of driving you do when selecting a spring rate.

Do these come with new upper mounts?

This QA1 coil-over kit does not include new upper mounts. You will need to reuse your existing mounts or purchase new ones separately.
