Get to know your setup.
Buying, fitting and looking after coilovers. A few useful reads while you compare this AST kit.
Choosing coilovers for road and track
Compare the kit against your roads, tyres and setup plans before counting adjusters.
Read the guideWhat spring rate tells you
Compare force and movement, read the units and choose a spring with the damper in mind.
Read the guideDamping adjustment explained
What combined, two-way and three-way controls change.
Read the guideRide height and spring preload
Understand the two adjustments before choosing a lowering range.
Read the guideIdentify the parts on your coilovers
Use the exploded view to name the component, then send the kit code for an exact replacement check.
Read the guideAlignment after changing ride height
Set the intended height, check the geometry and keep a useful record of the result.
Read the guideKnow what you’re choosing.
The controls and parts explained, before you decide.
Compare AST rangesThis kit: AST 5100 Street
Damping adjustment
Damping controls how quickly the suspension moves. A combined control changes compression and rebound together. Separate controls let you adjust them independently. More controls mean more setup choices; they do not guarantee a better ride.
Read the illustrated guideSpring rates
A spring-rate pair normally lists front, then rear. Keep the unit shown on the kit specification: kgf/mm (often written kg/mm) and N/mm are different units. The right rate depends on the car and setup. Ask us before choosing a custom rate or changing springs.
Read the illustrated guideTop mounts
Some kits reuse the original mounts; others include rubber or pillowball mounts. Camber adjustment depends on the mount and suspension layout. Check the exact configuration rather than assuming the representative photograph shows every included part.
Read the illustrated guideElectronic / adaptive dampers
If your car has factory electronic damping, tell us before ordering. The kit may retain that function, require an additional compatible cancellation solution, or have a specific exclusion. The correct answer depends on the vehicle and exact kit.
Ride height and installation
Lowering ranges and required parts vary by application. Read the kit notes and use a qualified installer. Changes to ride height affect alignment, so ask your installer to check the setup after installation.
Read the illustrated guideParts and servicing
Identify the component before asking for a replacement. Include the kit code, serial or batch marking and affected corner. The illustration names common external parts; the exact hardware and service route depend on this kit.
