2013 BMW 335i xDrive: Retrofit DHP (and other options)?

My vehicle wasn't ordered with DHP (a long story).

My goal is to get as close as possible to DHP-like ride quality _without_ lowering the vehicle, i.e. maintain OEM suspension geometry.

After researching available options ...

1. Try to retrofit DHP using BMW OEM parts. Did anyone try this? Cost? Would the BMW dealer even consider embarking on this journey? For a price, I suppose anything is possible.

2. Install KW's Dynamic Dampening Control (DDC) Coilover System. I contacted KW and European Auto Source to learn if this system will maintain OEM ride height. Waiting for an answer.

Thank you for sharing your experience.

Doesn't the KW DDC coil set hook up to the existing adaptive damper control system? If so, would it be possible to set this up to work with a non-DHP vehicle?

Anyways, if that works, I'm sure you can maintain stock height with the KW coils. I believe for most coils, if you raise it to the max, it will be higher than stock.

Hi guys.. i have a question about the xd models.. i own a 335xd m Sport.
I need to know if the 335 Xd Diesel has the same suspension setup as the 335 xi petrol model.. i know the exhaust pipe layout is different.. but does anyone know why the exhaust is different, and also if the suspension is different for some reason too??

Go for KW coilovers, I think I read somewhere that you will also need to change your sway bar because sway bar on a dhp car is different than a car without dhp. I could be wrong tho!!

Retrofitting isn't happening. Tons of wiring, different shocks, control module, etc. It would be cheaper to sell the car and replace it.
