So highest sitting so to speak is AWD suspension. A bit lower sits RWD (stock). Am I correct assuming that M Sport suspension on a RWD 335 sits a bit lower than stock RWD?

How does adaptive suspension changes things if any?

[BMW11]

i think its 10mm difference

Adaptive on a xDrive is same height as base suspension. Invest in some lower springs and shocks for the money you save from depreciation

M Sport suspension (RWD) is 20mm lower than standard.

Only 10 lower.

Unless by "standard" we mean xDrive...then 20 should be correct.

Pretty sure it's 10mm. 20 is almost an entire inch

79% of one anyhow,,,how does that make it hard to believe? The article is comparing it to a non-M sport RWD isn't it? The xDrive is higher than that.

Standard suspension is considered to be on RWD versions of Base, Modern and Luxury Lines.

RWD Sport and RWD M-Sport models are -10MM lower than standard (these have the 704 sport suspension). The RWD versions of Sport and M-Sport are 20MM lower (about 3/4") than ALL xDrive models.

ALL xDrive models are +10MM over standard and ALL contain same springs regardless of model (this includes Sport and M-Sport models). An xDrive must have DHP (Dynamic Handling Package) to adjust to a stiffer suspension, HOWEVER, this does not change the suspension height in either direction! Extra clearance is for winter conditions and for front wheel drive gear.

I believe this is all correct. Thanks kpgray!

I may have misread the question then. I was comparing RWD sport vs RWD non sport. You are correct the Xdrive could be 20mm higher than RWD sport.

This is incorrect. All Xdrive variants and the rwd standard suspension share the same ride height. Rwd with 704 or adaptive m drop it 10mm.

This is incorrect.

The xdrive suspension sits higher than standard (non sport) rwd suspension.

You are correct about him being incorrect. Correct me if I'm wrong.

No, you are correct about me being correct that he is incorrect.

So AWD sits 10mm higher than 704 RWD standard. Then M-Sport sits 10mm lower than 704 RWD standard. In other words there's a 20mm difference between AWD and RWD M-Sport suspension. I'm assuming besides ride height M-Sport has stiffer springs correct? Are shocks same or they have different stiffness too?

Well close, except the 704 is not the standard RWD suspension - it is the sport suspension without adaptive, so:

Lets use a RWD model without sport options as a baseline.

Xdrive - either with or without adaptive sits 10mm higher

sport or M sport - either with or without adaptive sits 10mm lower

I do not believe adaptive effects the ride height in either application, but not sure how the actual spring rates are effected - if at all. Adaptive changes the shocks/dampers so that they are adjustable via a valve to range from softer to firmer. System monitors all kinds of data to determine how soft the dampers should be and continuously adjusts them as you drive. Also comfort, sport & sport + has some effect on logic for adaptive dampers.

So yes, 20mm between Xdrive and sport

Yes stiffer springs, although exact specs are hard to pinpoint and yes, historically, shocks/dampers are different too and are matched with each of the 5 different suspension set-ups. FWIW, I researched this a bit and test drove and selected the non adaptive sport suspension - 704 and am very happy with it. I think it matched with the right tires is the typical BMW sport suspension, although other suspension set-up have merit for others.

This is not true, not sure where this myth about xdrive sitting higher than the standard rwd suspension came from, probably confusion because bmws literature is not super helpful. The 704 is 10mm lower than standard rwd or xdrive. But standard rwd and xdrive have the same height. You can grab a ruler and check. But it's obvious from the eyeball test that the xdrive cars do not sit an inch higher than the rwd sport suspension cars. They don't even sit an inch higher than the m3.

I doubt it's 10mm higher but even BMWUSA.com lists the RWD at 56.3" height and 56.5" height for xdrive

yea this is a huge mess.... thankfully they are fixing it on the G20 where all xdrive and RWD versions will have the same suspensions regardless of AWD or RWD

Yeah, I saw that too but 10mm is .4 inches - nothing matches up.

To my eye the xdrive looks higher - next time I'm at the dealer I will measure for myself.

I never considered the xdrive, so never looked super close at them - I spent my time comparing the various RWD versions as that is what I was buying.

So I swopped out my springs on my 2013 335i XDrive 6MT for a set of M Sport Springs from a 2013 335 M Sport RWD.....retained same shocks cos the XDrive fronts are different. Dropped the car 20MM all around. Reduced the roll almost completely and firmed up the suspension by a seat of the pants 10-15%.
