What is the benefit of external reservoirs on these coilovers?

External reservoirs help keep the damping fluid cooler under heavy use, which prevents shock fade. They also provide easier access to adjust the compression and rebound settings without removing the shocks.

How do I adjust the rebound and compression settings?

You can adjust the rebound and compression damping using the knobs located on the external reservoirs. Each adjustment position provides a distinct change in damping force, allowing you to fine-tune the suspension.

Do these coilovers come with everything needed for installation?

This kit includes the MONOTUBE coilovers, external reservoirs, springs, and camber-adjustable front top mounts and solid rear top mounts. You will need to refer to the manufacturer's installation instructions for any additional hardware or tools required.

Product Details

External reservoirs allow separate adjustment of rebound and compression damping. The AST 5200 Series coilovers for the 2005-2012 Porsche 911 997 (2WD) are built for serious track use. You can fine-tune your suspension for specific track conditions and driving style.

These are MONOTUBE coilovers with an inverted strut design. This setup handles heavy side loads and braking forces common in performance driving. You get the flexibility to adjust spring rates, rebound, and compression damping. The rebound controls how fast the damper extends, while compression controls how fast it compresses. With 12 distinct positions for each, you can dial in the perfect balance for cornering, traction, and even ride comfort. The kit includes camber-adjustable front top mounts and solid rear top mounts to further tune your front-end grip.
