The AST Suspension 5300 Series 3-Way Adjustable Inverted Coilovers represent a top-tier suspension upgrade for Porsche 996 Carrera 4, 4S and Turbo models, delivering exceptional control, adjustability and durability for fast road and track use.

Developed using AST’s motorsport expertise, the 5300 series features an inverted monotube damper design for increased rigidity, reduced unsprung weight and superior feedback under extreme driving conditions. Independent high-speed compression, low-speed compression and rebound adjustment allows precise tuning to suit road, track, or competition environments.

Designed and hand-built in the Netherlands, AST 5300 coilovers provide a significant performance advantage while maintaining ride quality and consistency—making them ideal for serious Porsche enthusiasts who demand ultimate suspension performance.

  • 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.
