Maybe I should have got the Adaptive Sport Suspension... :(

So it ends up being that the standard sport suspension on the MSport is grossly undersprung and underdamped. I don't know how much better the Adaptive Sport Suspension is and I'm left wondering how much better it would have been... Of course, people on this board were telling me to get the adaptive but I was too damn cheap to shell out the additional $1k.

If I had to quantify it, I would say that the standard sport suspension needs to have a 15-20% stiffer spring rate and 50% more dampening ability. The high speed dampening (quick stutter bumps) is ok but the low speed dampening (big undualtions or turns) could use quite a bit of help. The car wallows and takes too long to settle in fast sweepers.

I guess I can use this as an excuse to get full blown aftermarket coil overs.

No, it just gives you the ability to go softer so when you're downtown or going through construction, its more forgiving.

You driving this to the limit? As in no one else can drive this car faster than you.

False, adaptive sport is stiffer in spot mode than standard sport.

I don't know how you got that from my post. If you've ever done any amount of track time whether auto-x to road course, you would know that reaching limits of adhesion is not that difficult. Assessing what it would take to make the suspension perform better is half the fun. Just as is people trying to make the engine perform better, there are others trying to find an optimal suspension setup. What's wrong with that?

I didn't find the standard msport suspension that bad on my 335i. It was somewhat sporty but with a comfort tilt. I have since replaced it with the m performance and am thoroughly pleased. Maybe you should consider it. I'm in San Diego as well.

This is correct. Adaptive is both stiffer in sport mode, and softer in comfort mode, than the standard passive sport/non-sport suspensions, while also having more body control in BOTH modes, and constantly measuring the road to give the best result in both modes.

I could definately percieve a difference between the regular sport suspension and the adaptive m suspension in sport mode. I felt the regular sport had a little bounce and float around corners especially if there were any undulations in the pavement through the curve. It seemed to get a little unsettled and sloppy in certain situaitions for a BMW. The sport mode in the adaptive suspension mostly eliminated this. This is why I ordered my wife's car with adaptive m.

Just placed an order for an m sport 335i and wondering if I should have gotten the DH package. Is the steering any tighter with the adaptive suspension? I have it on my z for but wasn't sure if it was worth it or not on the new car. I could care less about comfort mode but if there is a big difference between sport mode and the m sport suspension I might have to change my order

When in sport, you get heavier steering regardless of what other option you got. Variable Sport Steering, which is the other part of the adaptive package, doesnt affect the weight of the steering, only ratio.

But you should absolutely, most definetely, without a single doubt, get Adaptive M Supension.

Really? Can someone show/confirm this? Maybe through part numbers etc?

Don't get me wrong at all, I'd love for the M-Adaptive to be stiffer than the normal sports suspension, but all I have is word of mouth to go on. And all that does is cause endless debates on no real facts.

For example, my source was a BMW race engineer at a BMW drive event. Admittedly, the Adaptive was just coming out at the time. I specifically asked him while in Sports mode if the suspension would be stiffer than the normal sport suspension. He said no. But then again, it was new at the time and he may not have had a chance to look at it.

Still, I find the M-Adaptive "feels" less stiff than my old e90's ( although I am on winter non-RFT's right now, but I am trying to compare winter apples to winter apples ).

M Adaptive in Sport feels stiffer to me than a normal Sport Line car in Sport mode.

Dunno if part numbers will clarify anything, because some of this is going to be software related.

All I know is M Adaptive is the best $1K option I ever got on a car.

I think the only reason for not getting the adaptive would be if you're planning on installing aftermarket suspensions, then you save $1000, and I've heard that it was easier to install the aftermarkets if you don't have to undo all the adaptive hardware and software.

But no aftermarket is going to give you that variable suspension setup... Just a stiff setup, assuming you're going for sport suspensions.

Exactly! Coming from an M3, I can tell you that a very stiff suspension 100% of the time is not very fun.

If I'm just cruising along on the very straight roads we have here in TX, then Comfort with M Adaptive is perfect. When I get to some curves or on-ramps, it only takes me one second to flip over to Sport.

Very cool! Can you PM me with the specifics. Maybe you can take me for a spin sometime. I would love to assess the difference between cars with M Sport and M Performance suspension.

I'm getting the front splitter on today if you haven't seen that. I'm hoping it looks good on a stock height car. I'll have to take pics and post them.

Seen it? You seem to have it!! I just picked mine back up 10 minutes ago. Love it! Looks like you got the whole kit. I'd like to check out that rear diffuser.

Is it possible to put in the M performance suspension if you have the adaptive suspension? Would that eliminate the adjustability?

as far as i know BMW has not released an adaptive version of their performance suspension. However, i have read that there will be a version available sometime. It's hearsay, nothing definitive but i think you'll see it eventually

Looks like you went with BMW Encinitas too..Work with service advisor Sean Puno and their Tech Ian. Mention James.

What part of town are you in? Im in Del Sur/Santaluz
