Motorsport pedigree gets thrown around loosely in the suspension world, but AST actually earns the phrase. Built in the Netherlands and developed through endurance racing, including Nürburgring 24 Hour programmes, AST coilovers bring genuine race engineering to road and track cars.
At Pro Speed Racing, we help enthusiasts find the right AST setup, from the street-focused 5100 series through to multi-adjustable 5300 track weapons. Every AST damper is hand-built, dyno-tested and fully rebuildable, for drivers who take their chassis seriously.
We do not store every AST kit on hand, but our sourcing network gives you access to AST product direct from the manufacturer. If you need a specific series, spring rate or chassis fitment, Pro Speed Racing can help source the right gear.

The series structure is what makes AST easy to buy well. The 5100 line delivers race-bred damping in a street-friendly package, the 5200 adds adjustability for serious track work, and the 5300 gives dedicated competition cars the multi-way control they demand.
Rebuildability is the quiet advantage. Where sealed budget coilovers become landfill when they wear, AST dampers can be serviced, revalved and refreshed in Australia, so the kit evolves with your build instead of being replaced by it.
