i have pulled the trigger.
I have a 335d xdrive just ordered bilstein b8 shocks this will pair up with acs springs that are already installed on the car(but have busted the front stock shocks in 10k miles since installation - could be a coincidence as car has done 50 k miles in total ). B8 Shocks will be with me on thu. I will get them installed next week. will post a review as soon as I have them installed. |

The shocks have been delivered
i have compressed thrm by hand rear seem quite soft and compressible front seem firmer. The fronts after they compress 2/3 they hit the gas chamber i think and then it is quite hard to compress them though still can be done. Installation of the shocks booked for monday Getting front strut mounts and drop links also changed at the same time. hope this isnt overkill. |

interestingly the b8 seems to be common across the f series ie b8 that fits on f30/31 xdrive also fits on f34 xdrive as shocks are marked f20-36 4wd

As you can see the before pics were acs springs and stock shocks. The after shots are acs springs with b8 shocks. Front sits about the same height. Back sits higher though.

ride height
i don't know if the acs springs were compressing my stock shocks too much but yes with acs springs and b8 ride height is lower than stock shocks with stock springs. with acs springs and stock shocks the front ride height was about the same but rear ride height is slightly higher.

steering feel.
i am blown away by how much more responsive the steering feels. Previously with stock shocks there was vagueness and understeer but with b8 and acs springs the steering in comfort mode goes exactly where u point and back follows through. I would say it has gone from understeer and vagueness to great steering feel in comfort and tad bit oversteer. If there is a 90 degree turn in the road to the left and i turn left the left front wheel goes close to the kerb and left back wheel follows suit no touching the kerb. No drama. very surprising. comfort and stability and other parameters review to follow soon... |

Bilstein dampers raise the ride height for a couple of reasons. In the front the spring pad base isn't as slanted/curved as the OE base, and seems to be placed a bit higher than the OE struts. Additionally you have much higher gas forces exerting an additional 40-50lbs of force upwards. So if you were to calculate the compression of your springs you'd subtract 40-50lbs per corner to see the true amount of compression.

Ok, now I'm confused by this last post...OP says the combo rides lower than stock, but you're saying it is higher?
I get the physics concept that the stiffer damper might push up a bit more than stock thus raising the height, but from what I could tell on the Bilstein site filtered for a 14 335GT xDrive: B4 is for OEM replacement B6 is performance upgrade for use with OEM springs B8 is performance upgrade for use with lowering springs Also it's pretty hard to judge based on those pics because of shadows and wet vs dry tires, might create an illusion there. |

Ok I was so dissatisfied with my 335 drive gt when I bought it. power plant was excellent but suspension and steering were shit.
ACS springs and installation £700 Ditched tun flats for Michelin pilot sport 4 £800 Bilstein b8 shocks and installation £900 New drop links and shock mounts £300 roughly £3000 all in all from purchase to now. But Im so much in love with my car now. £3k is small change for a car thats stable fast responsive silent comfortable and one that i plan to keep for at least another 3 years.. More to follow.... |
