AST 5100 Series Shock Absorber Coil Over 2016+ Porsche Cayman / Boxster 981 / 718 Without Top Mounts

Already running a performance setup on your 718 Boxster? This AST 5100 Series coilover set is the next piece to dial in your suspension. These are designed for drivers who want to maximize grip and control their car's ride height and rebound damping for better road balance, whether for daily driving or spirited runs.

The AST 5100 Series uses a monotube damper design. This means a larger piston inside, which gives you more precise control over the rebound adjustment. Monotube dampers also prevent aeration and foaming, so the valving stays responsive. You get 12 distinct positions to adjust the rebound, letting you fine-tune how the suspension returns after compression. The spring rates are pre-set based on AST's development and testing, but you can easily adjust the ride height and rebound to match your preferences.
