Bilstein B4 OEM-type direct replacement rear shock for E90 E92 RWD w/ Sport Pack. This includes the 2006-2010 3 Series 4-door RWD Sedan (325i, 328i, 330i, 335i, 335d) and the 2007-2010 3 Series 2-door RWD Coupe (328i, and 335i). This rear shock is calibrated for cars with the Sport Package suspension - but can also be used on cars with the "base" (non-sport) suspension if you'd like a slightly sportier ride and handling. There is only a very small sacrifice in ride quality, much like the factory BMW sport package, which is only ever-so-slightly firmer in it's damping and response. 

Fitment Notes: 

 - Not for cars after the 2010 model year. This rear shock is for the earlier (2006, 2007, 2008, 2009, and 2010) models. 

 - For coupe and sedan models ONLY. Not for body styles other than 2-door coupes and 4-door sedans. 

 - For RWD (rear wheel drive models) ONLY. Not for cars with xDrive/AWD system.
