Bilstein B12 Spring and Damper Package for BMW 3 Series Cabriolet E93 - Part No. 46-180674

Give your BMW 3 Series E93 Cabriolet the chassis upgrade it deserves with this Bilstein B12 spring and shock absorber package. Purpose-built for the 2006 to 2013 E93 convertible platform, this matched set delivers razor-sharp steering response, reduced body roll and a purposeful ride height drop for a cleaner stance without ruining comfort on daily drives.

We have installed this kit on customer cars and our own builds, and feedback is consistently positive: better turn-in, more confidence mid-corner and a calmer, controlled ride on B-roads and motorways alike. It is the ideal fixed-height alternative to coilovers for drivers who want road-friendly performance and OEM-grade reliability.

Why this Bilstein setup works on the E93

• Vehicle-specific valving and spring rates tuned for the E93 cabrio shell and weight distribution.
• Lowered centre of gravity for improved grip and stability with a tasteful, even drop.
• Matched springs and sport dampers that work together to enhance traction and ride control.
• Direct-fit replacement for tired factory suspension with no coding or cutting required.
• Sporty yet compliant road manners suitable for daily driving and fast road use.
