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.
