330i sport shocks replacement
I got an 330i 2006 with the sport package. Both of my rear shocks are leaking and I want to replace them but I have a really hard time to find the right components. I want some Bilstein but I cant find any parts number for my car with the sport option
I took a look on ecs tuning and the part number is different from the bilstein website The part number from the Bilstein website seems to be for 335i, can someone help me find the right part number lol |

You can use 335i shocks no problem
Bilstein B8 is the sport shock for lowerign springs I believe. Bilstein B6 is Bilstien HD in NorthAmerica - ist more for OEM sport

I have to differ from the posts above. I have been informed by Bilstein that the following are the guidelines for these cars.
B6 (HD) is for factory springs - BOTH sport and non-sport springs B8 (sport) is for use with aftermarket lowering springs - e.g. eibach or H&R |

Does the B6 or HD offer improved handling while maintaining ride comfort? I do not track my car but just want it to handle better. Ride comfort is important to me. Is the B6 what I should go for?

Here is what Bilstein on-line catalog says:
BILSTEIN - B6 Adjustable 10 Gas Pressure, for vehicles with standard chassis BILSTEIN - B6 SPORT Gas Pressure, for vehicles with standard chassis BILSTEIN - B8 SPRINT Gas Pressure, for vehicles with M-technology BILSTEIN - B4 Gas (Ersatzteil) Gas Pressure, for vehicles with standard chassis BILSTEIN - B4 Gas (Ersatzteil) Gas Pressure, for vehicles with sports suspension Based on this there is no B6 for sport suspension. M-technology springs are lowering very similarly to typical Eibach (eg. ProKit) or H&R - I guess it is -25mm and -35mm respectively - so shorter shock B8 will work better with it, than stock length B6 or B4. I followed this classification and for my car with option S704A (M Sports suspension), I picked B8 and I am more than happy. |

Notice in the description of the B8 and the B4, they call out a difference between M-technology and Sports suspension. |

andrey_gta, thanks for the information on Canadian Sport suspension. Does that mean there is no such thing as M-Sport in Canada?
What's the difference between B4 and B6? Does the B4 offer more ride comfort than the B6? |

sport and msport are the same thing.
B4 are oem type twin tube shocks. B6 and B8 are monotube design - what many people consider a vastly superior design in many aspects. |

Thanks cdgatti. So back to my question -- handling aside, does B4 offer better ride comfort than B6, which in turn offers better ride comfort than B8? Is that the correct interpretation?
