Bilstein B12 Pro-Kit – BMW 328i / 335i (E93 Convertible)

OVERVIEW

If you are looking for the perfect combination of sport dynamics, superior appearance and high performance for a 2007–2013 E93 3 Series Convertible, the BILSTEIN B12 (Pro-Kit) is the right track. This matched kit is put together for the E93 3 Series Convertible, including the 328i, 335i and 335is.

The kit provides a dramatic increase in the convertible’s performance handling characteristics and is designed for drivers wanting precision control and superb driver comfort, while seeking out more curves to conquer. BILSTEIN calls the matched damper-and-spring approach its Professional Cornering System (PCS): precise response, excellent performance, predictable control and a lower, action-ready looking vehicle.

The B12 (Pro-Kit) is the product of two companies at the top of their industries: the shock absorber experts at BILSTEIN and the spring professionals at EIBACH.

Notes

• BILSTEIN lists this kit for the BMW 328i 2007–2013, 335i 2007–2013 and 335is 2011–2013. This is the E93 convertible kit; not for xDrive models.
• Speed Logic experience: while this kit will physically fit the 335is Convertible and E93 convertibles with the M Sport Suspension option, we have found it does not noticeably lower those cars. If you want a lowered stance on one of those cars, contact Speed Logic for better options.
