Buying, fitting and looking after coilovers. A few useful reads while you compare this Bilstein kit.

All buying guides

Coilovers or lowering springs?

Choose around the height adjustment and damper changes your car actually needs.

Read the guide

Ride height and spring preload

Understand the two adjustments before choosing a lowering range.

Read the guide

Alignment after changing ride height

Set the intended height, check the geometry and keep a useful record of the result.

Read the guide

What spring rate tells you

Compare force and movement, read the units and choose a spring with the damper in mind.

Identify the parts on your coilovers

Use the exploded view to name the component, then send the kit code for an exact replacement check.

Wheel and tyre clearance with coilovers

A wheel diameter alone cannot confirm clearance to the spring, damper or body.

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 guide

Spring 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 guide

Top 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 guide

Electronic / 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.
