335d x Drive suspension
Hi guys, new member here so apologies if I've duplicated a post/ in wrong area!
I've noticed people have changed the springs to slightly lower the car, has anyone done this yet to the 335d? I've had mine since September and covered 30k, the one thing I miss is the sleek low look of my e92 coupe :-( Don't get my wrong, the car is fab and if it can't be done so be it as it's so good in all other ways! Cheers guys! |

There are some who intend to lower their 335d (me included). But the jury is still out on the implication of lowering an X drive.
I for one will be waiting for more info to become available before taking the plunge. |

Hi Daz, ok cheers so where are people with it do you know, has anyone you know of actually done this? All it needs is 15-20mm which won't have an effect, if it does swop it back simple but can't see any issue? I've drove to France with 400kg of people and gear in tow flooring it hard most of the way so you can imagine the ride height for them miles looked great! :-)

I don't think it's due to it not having an effect more a case of if you do it and break something serious then BMW may not cover it. |

Guys, I've done a bit of digging today on the suspension, I've spoken to a couple of manufacturers and it seems there is no problem with doing it at all! You can choose from 15mm drop up to about 35mm, I'm going to look at a demo car Wednesday so I'd anyone wants any further info give me a shout :-)

Will you just look or will you get a test drive to feel any difference in ride or handling?

I spoke to ACS but their springs lower a 335d a lot! I'd be interested to know your thoughts... |

Of course non-BMW manufacturers are going to say its fine to change the springs - they are trying to sell them, but will they pay out if it causes problems to the xdrive a few miles down the road? Probably not. I dont think BMW will recommend it - for whatever reason. Until BMW endorse the changing of springs on xdrives, I think I'm going to stay well away.

But there again BMW dont recommend swapping to non-run flats, but that didnt put me off swapping with my last car.
But I think there must be a reason why these springs are fitted to the xdrive models.

The concern I would have is would an insurance company pay out. Also who ever gets it done will need to look closely at the technology used. |

I honestly can't believe the likes of kW or H&R would launch lowering springs that compromised the mechanics of the car. The impact on their reputation would be significant and they will undoubtedly make sure they test any potential consequences of fitting change springs as part of their development process.
I don't think you'll ever see bmw endorse any aftermarket changes to be honest - non-run-flats are a case in point. Last edited by Cootie; 03-04-2014 at 08:36 AM.. |

I suppose it also depends how we evaluate risk. Say we get a knocking front suspension or driveshaft vibration, a whine from the transfer case, are we prepared to foot the cost of fixing it even during the warranty period, if BMW play the 'modified car' card. Burden of proof is much harder with any modifications. Clearly a lowered spring on an xDrive car could be the cause, (BMW don't offer a OEM option), plus the small print is pretty clear on user modifications and warranties. HighlandPete |

Be thankful we're not talking about Porsche warranties for 'get out clauses': fit wiper blades yourself and your warranty is gone. (Note this is extended warranty, not the manufacturer's warranty)

I can't really complain about Sandal BMW Wakefield. My car goes back next Tuesday (not to them) It was in for a major service last week, they noticed my 19'' M performance alloys were corroded slightly at the centre caps (all 4 wheels). The car is 2 and a half years old with 90k on the clock. They are changing all 4 wheels under warranty, they know the car goes back and I get my new one in a week too!

@HighlandPete I'm sure you mentioned in another thread that the higher suspension may contribute to better traction for the xdrive? Or was that a thicker ARB? (cant remember now!)
That's just bonkers.

What we don't know is what a simple suspension change, springs or ARBs will do to the xDrive balance. BMW clearly state in xDrive data that weight transfer is part of the control strategy. How a lower/stiffer spring or stiffer set of ARBs would change the finer response of front to rear drive ratio, can not be known without BMW development test data or trial and error. Whether BMW will ever offer a performance based xDrive option, we have to wait and see. HighlandPete |

I was going to get an x drive until I read that it was not lowered and did not come with the M Sport suspension.
I'm guessing this was done due to good reason, hence I changed my whole speck and got a 328i RWD M Sport |
