Bilstein B14 PSS Coilover Kit – BMW 2 / 3 / 4 Series (F22 / F23 / F3x)

OVERVIEW

The Bilstein B14 PSS suspension gives you adjustable vehicle ride height without the expense of a fully adjustable damping system. The kit combines coilover front struts and standard monotube gas-pressure dampers with performance-level valving, matched to application-specific progressive-rate coil springs.

It is designed for rear-wheel-drive F22/F23 228i and 230i, F30 320i, 328d, 328i, 330e, 330i, 335i, 340i and ActiveHybrid 3, and F32/F33/F36 428i, 430i, 435i and 440i models without factory Electronic Damper Control (EDC). Ride height is set on the threaded damper bodies, so the car can be dropped to taste while damping stays matched to the spring.

Every B14 kit is road-tested and fine-tuned by Bilstein ride engineers under extreme motorsport conditions, and is made in Germany.

TECH RESOURCES

Additional Parts Required

• Not for cars with factory Electronic Damper Control (EDC / Adaptive M Suspension). Bilstein lists this kit for vehicles without EDC only — confirm your car does not have EDC before ordering.
• Recommended tool: Bilstein spanner wrench set E4-XS1-Z001A00 for setting ride height on the threaded damper bodies.
• A four-wheel alignment is mandatory after installation — changing ride height alters camber, caster and toe.
• Professional installation is strongly recommended. Spring compressors and BMW strut tooling are required, and the front strut assemblies are under spring load.
• Re-check ride height and re-torque the fasteners after the springs have settled, then re-align the car if the height is changed again later.
