Bilstein B16 PSS10 Comfort Coilover Kit – BMW F22 / F30 / F32 (RWD)

OVERVIEW

The engineers at Bilstein created the ultimate race-inspired suspension: the B16 PSS10 — and this is the Comfort Edition, tuned with less overall lowering 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, 330i, 335i and 340i, and F32/F33/F36 428i, 430i, 435i and 440i models.

TECH RESOURCES

Additional Parts Required

• None. Bilstein supplies this as a complete front and rear kit and specifies no additional hardware for installation.
• 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.

Installation

• Bilstein shock absorber installation safety notice (PDF)

Notes

• Rear-wheel-drive models only; xDrive cars use a different Bilstein kit. Where Bilstein does not publish a model-specific year range (435i, 440i, ActiveHybrid 3), the years shown are carried over from the original listing — confirm fitment with Speed Logic before ordering.
