AST Suspension 5200 2-Way Adjustable Inverted Coilovers – Porsche 987 Boxter - 2005 - 2012

The AST Suspension 5200 2-Way Adjustable Inverted Coilover Kit is a high-performance suspension solution developed for Porsche 987 Boxter & Cayman, delivering exceptional control, adjustability, and durability for fast road and track use.

Featuring inverted monotube dampers at the front, the AST 5200 system offers increased stiffness and reduced unsprung weight, resulting in sharper steering response and improved front-end stability under high loads. With independent adjustment for rebound and compression, drivers can precisely tune the suspension to suit road conditions, driving style, or circuit demands.

Hand-built in the Netherlands using premium internal components, the AST 5200 kit is engineered to provide consistent performance, long service life, and outstanding feedback—making it an ideal upgrade for enthusiasts seeking maximum confidence and control from their 987.

  • Upgrading: AST 5100/5200/5300 “5000-series” dampers are built modularly and can be upgraded, but what’s involved depends on which step you’re taking and your exact Porsche chassis/kit spec.
    
    

  • 5100 → 5200 or 5300: Generally possible by sending the dampers to an authorized AST rebuild/upgrade center to add the required internals and remote reservoirs (and associated hardware). This “upgrade path” is a commonly stated feature of the AST 5000-series modular design.
    
    

  • 5200 → 5300: Typically the straightforward upgrade (adding the extra compression circuit/adjustment hardware). Many dealers describe the 5200 as a good “start here, upgrade later” option for that reason.

• Installation: Professional installation and geometry setup recommended:

• PASM Vehicles: Vehicles fitted with Porsche Active Suspension Management (PASM) will require coding to prevent faults & error messages & correctly disable the system. 
  As an alternative option, where access to coding is not possible, a PASM cancellation kit can be purchased through us at RW Performance. If you are unsure and need any technical advice, please contact a member of the team!
