Product Description

Engineered for drivers who demand the highest level of chassis performance, the AST 5300 Series Coilover Kit is a race-proven suspension system designed to unlock the full handling potential of the Porsche 987 Boxster / Cayman. Featuring independent rebound, low-speed compression, and high-speed compression adjustment, this 3-way coilover system gives you complete control over how your Cayman performs on both the street and the racetrack. Large external reservoirs improve cooling and increase oil capacity, providing exceptional damping consistency during extended high-performance driving. The inverted monotube front struts are designed to withstand the extreme cornering and braking forces generated on track, while ride height adjustability allows you to dial in both the perfect stance and suspension geometry. Whether you're building a dedicated track car or a weekend canyon carver, the AST 5300 delivers championship-level performance with uncompromising precision.
