I have another question for you. My Mercedes has a very rough ride. I can feel every bump in the road. It has the Sport Pkg suspension which lowers the front by 0.5". Do you think the B8s would soften the ride? |

What's the current mileage on the Mercedes, and are the struts original? Installing new dampers will always feel like a night and day transition compared to the old, worn units. Bilstein shocks and struts also use gas pressure dampening, which some find a bit too harsh at times. In my opinion, I found the valving of the Bilstein dampers just right. They could shrug off high speed road imperfections without breaking a sweat, and made for much more compliant handling over poor road surfaces at low speeds, where my car used to tramline and translate every little bump right into the cabin. |

My Merc, a 2010 SLK 350, only has 15K miles on it. It's kind of a bauble. I've always wanted a 280SL, but by the time I had the coin to afford one, a really nice one would have cost me over a $100K! The SLK is a substitute for the 280SL. I never drive it in the winter or rain. In fact it's garaged 6 months out of the year, and when parked, it's always put in the garage! Anyway, the suspension is all original. |

Was searching through an alternative for eibach springs that come with B12 Pro-Kit and found this thread. I have been riding on B12 Pro-kit with eibach and the ride, to me is really hard. It's great on the track but I would like to sometimes use this car for road trips too. (Anyone for a trip to Tail of dragon?)
Recently, my driver side rear shock mount blew because of some bad pothole. I have decided, while replacing the the mount, I'll replace eibach with Performance springs.

Question! I am about to purchase the Bilstein B8 shocks to pair with my factory m-sport package E82 135i w/ N55.
Do I need to purchase bump stops? I heard that they come with bump stops built in for both front and rear dampers. Just want to confirm before I make an order. Thanks! |

I recommend you replace all the small rubber pads/pieces/seals while you are doing that, they are relatively cheap. |

Thanks for the answer! I heard recently that only the fronts have bumpstops built in and that rear bumpstops are still required. Correct?

Nope - rears are inverted design also, with integrated bumpstops. Everything else in assembly of the front and rear remains the same as factory, except the bumpstops.

Bilstein B12 Pro-kit...

IDK about the B8 Bilstein shocks... but I just bought a B12 kit(for my 135i) and the rear bump stops come with the rear shocks(beige rubber bump stops). Both front and rear shocks come with dust covers too(blue accordion style). Maybe asbrr was referring to the front shock bump stops and the shocks being inverted. IDK ??? I bought all new hardware and rubber upper and lower rear shock mounts. Typically the rear upper shock hardware is shot when it comes to replacing shocks. EIBACH BILSTEIN B12 PRO-KIT... rear shock Bilstein part number... rear shocks... they come with the blue dust cover and the white/beige bump stop and the big washer. The other parts, upper rear shock mounts - to the right in the pic... I bought to replace the old worn out parts.

Argh godammit - sorry guys. It's been a couple of years since my suspension went in, Dackelone is right, the fronts are an inverted monotube design strut. The rears are a standard design - and have external bump stops as his pictures clearly show...
Been a rough few days...sorry! |

There's a Huge Mistake in This Thread!
I have '12 135i with the M-Sport suspension. Just for the heck of it, I had a discussion with Bilstein Technical support. First, the M-Sport suspension is around 20mm, or thereabouts, lower compared to the standard suspension package. BTW, does anyone have the standard suspension on this forum?
Anyway, many of you think the Bilstein B8s are the correct replacement shock/strut for the M-Sport suspension. Well I've got news for you! It isn't. The B6 is the correct part! Here are the facts. The B8 & B6 are identical in every respect except one. They both have the same physical dimensions and damping, but the B8 has a slightly shorter stroke. If you don't believe this call or write Bilstein Technical Support. Give them your BMW part numbers, and they will cross reference them to give you correct part. |

Research first then buy.

I've taken the time to investigate this matter. Here's part of Bilstein's response when I asked B6 or B8 on my 2010 SLK with Sport Pkg and 2012 BMW 135i with M-Sport Pkg: "We would recommend using the B6 shocks for both cars. The B8 should only be used if the coil springs have been replaced with aftermarket lowering springs. The B6 shock is for the stock coil springs." Further on in Bilsteins response, they gave the OEM part#s and the corresponding Bilstein part. The shorter stroke of the B8 won't allow the stock spring to function correctly. Now if you install the BMW High Performance Springs, the B8 might be the correct part. To be sure, just run the part numbers past Bilstein. They can cross reference them. |

p.s. The stock M-Sport suspension did change from progressive to linear springs in 2011, and I’m not aware of any ride height differences, although I guess it’s possible. |
