AST 5100 Series 1-way INVERTED CO Suspension for Porsche 997 GT2/GT3/GT2RS/GT3RS - 2007-2012

AST 5100 Series 1-Way Inverted Coilover Suspension

Porsche 911 (997) GT2 / GT3 / GT2 RS / GT3 RS | 2007–2012

The AST 5100 Series 1-Way Inverted Coilover Suspension system is a high-performance suspension upgrade developed for Porsche 997 GT-series models, delivering exceptional control, durability, and driver feedback for fast road and track use.

Featuring inverted monotube dampers, the AST 5100 system offers increased rigidity, reduced unsprung weight, and superior resistance to side loads—ideal for high-grip driving and demanding circuit conditions. With a single-adjustable damper controlling both compression and rebound, the system allows quick, effective setup changes while maintaining predictable and confidence-inspiring handling.

Hand-built in the Netherlands using premium internal components, AST coilovers are widely trusted in motorsport and performance road applications for their consistency, reliability, and tuning range.

  • 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 is 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!
