Rear Air Spring Retrofit
Has anyone here retrofitted a rear air spring setup to replace the traditional suspension? I'm just curious as I'm looking to accomplish two objectives on my X5:
1) Ability to get a dropped look while maintaining better ride comfort over traditional lowering springs and 2) Adjust ride height based on tow loads. When I saw retrofit in this thread I'm talking about using an aftermarket system in conjunction with either the OEM air springs or an aftermarket set. I've seen a complete D2 system go for $2k but that seems to be for front and rear, I'm primarily focused on just the rear at the moment. I'm still doing some research but curious to see comments from those who may be familiar or have experience with these setups. Thanks |

If using the OEM setup the rear is not going to go up and down as you wish. There is no button to give you the desired height. If that's what you want you, scrap whatever you have now and just go with aftermarket and call it a day. Good luck. |

Your trying to retrofit aftermarket to OEM? The stock air bags are shitty and the compressor is just ok. I replaced the airbags in 45 minutes on both sides. The aftermarket ones recommended are Arnott if going with OEM type. Aftermarket all the way for what you want to do. |

So bringing this thread back. My thoughts were to use Arnott rear air springs since they will drop right in and they are reasonably priced. I'm not sure how the ride quality is but I imagine that even lowered, they are probably more comfortable than a traditional lowered spring which is what I have now.
As for the electronics I was thinking aftermarket as well. It seems like there are some pretty basic kits I could get for a few hundred or I could always spend a little more and get a management system that automatically adjusts the level based on my preferences. Of course the part I like about this is that if I ever decided to do air bag struts in the front, I'd already have the system. |

I am looking at installing exactly what you are describing. I am wanting to tow a ~4,500 pound TT without using a WDH or Friction sway as is recommended by BMW.
To do this I need to raise the end of the BMW when towing for obvious reasons. Did you even install the set-up you described? Did you have BMW install it? Overall cost/time? Parts? |

Also curious- Towed my car on my car hauler for the first time this weekend, curious about levelling the suspension. What're the arnott bags like? I'd be interested to know where they actually sit, because if the mounting points are there, I see no reason why I couldn't run a tiny compressor to fill the bags.
