Bilstein B14 PSS Coilover Kit – BMW E82 / E90 / E92

OVERVIEW

The Bilstein B14 PSS suspension gives you adjustable vehicle ride height without the expense of an adjustable-damping system. The kit combines performance dampers with application-specific progressive-rate coil springs, tuned together for each application.

The zinc-coated, threaded body design provides ride-height flexibility and corrosion protection, for the E82/E88 1 Series (128i, 135i, 135is) and the rear-wheel-drive E90, E91, E92 and E93 3 Series.

Every B14 kit is road-tested and fine-tuned by Bilstein ride engineers, including at the Nürburgring, and is made in Germany.

TECH RESOURCES

Additional Parts Required

• Recommended tool: Bilstein spanner wrench set E4-XS1-Z001A00 (sold separately) for setting the threaded ride-height collars.
• 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.
