Bilstein B12 Pro-Kit – BMW M3 (E90 / E92)

OVERVIEW

If you are looking for the perfect combination of sport dynamics on a 2008–2012 BMW M3, as well as better-than-stock appearance and handling, the BILSTEIN B12 (Pro-Kit) suspension package is the right track. It is designed for drivers wanting precision control with a maintained level of comfort.

A set of BILSTEIN Performance dampers and EIBACH Pro-Kit springs are tuned to complement each other — BILSTEIN's Professional Cornering System (PCS): precise response, predictable control, moderate lowering of 24–40 mm depending on application, and a lower, action-ready looking M3.

Contact us if you need assistance selecting your E9X M3 suspension — we are experts on the E90 and E92 M3 V8 platform.

TECH RESOURCES

Additional Parts Required

• Check EDC. Confirm whether your M3 is equipped with Electronic Damping Control (EDC) before ordering — BILSTEIN catalogs a separate B12 (Pro-Kit), 46-276346, for the E9X M3; contact Speed Logic to confirm the correct kit.
• Four-wheel alignment. A full four-wheel alignment is required after installation.
• Professional installation. BILSTEIN requires that the work be carried out by a qualified technician on a chassis hoist with proper spring-compression equipment.
• Installer-supplied: chassis hoist or jack stands, spring compressor and a torque wrench — do not use impact tools on suspension fasteners.

Installation

• BILSTEIN shock absorber and spring mounting instructions (E4-WM5-Y180A00, DE/EN, PDF)
• BILSTEIN strut / shock absorber mounting instructions (E4-WM5-Y065A00, DE/EN, PDF)

Notes

• BILSTEIN lists this kit for the BMW M3 2008–2012. BILSTEIN publishes general mounting instructions rather than a vehicle-specific guide; use them alongside the BMW factory repair procedure.
