AST Suspension Coilovers

AST Suspension builds premium motorsport dampers in the Netherlands, trusted by professional race teams across the world. At Springrates we carry the full AST coilover range, from the monotube 5100 Series to the multi-way-adjustable 5200 and 5300 kits.

Motorsport-Grade AST Coilovers

AST is a proper motorsport damper manufacturer, not a rebadged import. Their coilovers use high-quality monotube and twin-tube construction, are fully rebuildable and revalvable, and are developed on real race cars. If you want a coilover that can be tuned and serviced to keep pace with a serious build, AST is where the conversation starts.

The AST Coilover Range

The 5100 Series is the entry point, a fixed-damping monotube kit with excellent ride quality for fast street and track use. The 5200 Series adds 2-way damping adjustment for independent bump and rebound control, and the flagship 5300 Series offers full 3-way adjustment for dialing in a car at the highest level. AST also offers lowering springs for a simpler upgrade path.

Who AST Coilovers Are For

AST suits the driver who takes performance seriously — the track-day regular, the club racer, the enthusiast who wants a damper that can be revalved as the build evolves. It's a premium investment, and it rewards you with the adjustability and rebuild support that budget coilovers simply can't match.

FAQs

Are AST coilovers worth the money?

If you take track performance seriously, yes. AST is a genuine motorsport damper manufacturer with fully rebuildable, revalvable kits developed on race cars. They're a premium investment that rewards you with adjustability and long-term serviceability budget kits can't match.

What's the difference between the AST 5100, 5200, and 5300 Series?

The 5100 is a fixed-damping monotube kit for fast street and track use. The 5200 adds 2-way (bump and rebound) adjustment, and the 5300 offers full 3-way adjustment for the highest level of tuning. All are rebuildable.

Are AST coilovers good for the street?

Yes. Despite their motorsport pedigree, AST kits — especially the 5100 Series — ride well on the street while giving you serious track capability. They're a favorite for fast-road and track-day cars.

Can AST coilovers be rebuilt and revalved?

Yes. AST dampers are fully rebuildable and revalvable, so they can be serviced and re-tuned as your build evolves. That serviceability is a big part of the value in a premium motorsport damper.

Where are AST coilovers made?

AST Suspension manufactures its dampers in the Netherlands and supplies professional motorsport teams worldwide. It's a true engineering-led brand, not a rebadged import.

Do I need an alignment after installing AST coilovers?

Yes. Any ride-height change alters camber and toe, so an alignment is required afterward — corner weighting is also worthwhile on a track-focused AST setup.
