Product details
OVERVIEW
The engineers at Bilstein created the ultimate race-inspired suspension: the B16 PSS10 — and this is the Comfort Edition, tuned with softer springs and a more comfort-oriented base ride for the street.
The manually adjustable monotube gas dampers offer ten precise compression and rebound settings, from maximum comfort to a sportier ride, selected by the twist of a dial. The threaded damper bodies allow accurate adjustment of the front and rear progressive-rate springs, so you can set vehicle ride height, center of gravity and handling balance exactly where you want them.
This kit 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).

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.
- Damping is set by hand at each corner — allow access to all four dampers when choosing ride height, and set front and rear to matching positions before road testing.
- 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.
