It's a problem for BMW in the last few years on several models where the suspension just doesn't have the range of adjustability that other manufacturers have been able to get out of their adaptive struts. Comfort should mean comfort, and Sport Plus should be Sport Plus.

I do agree that comfort mode should be more compliant for those that want that. as it is now, not so much

this has been improved for G80. I test drove one and Comfort is really very comfy.

My bank account didn't want me to hear that.

So are you getting one instead of an X5M?

Quick Q - mine has the MSS installed and obviously has been lowered. Is currently in at BMW and they are attempting to 'reinstall all software' in response to some 'software fault' that was diagnosed last week that had resulted in the car reverting to a 'reduced power mode'. I'm being told that software won't install because the lowering of the vehicle has affected the active headlights and some sensor related to these. Does any of this make sense?

Possibly - if the level sensor was damaged during the installation. However, I think you would have gotten a fault code immediately. I believe the headlights use this sensor located on the drivers side:

Why not both?

No X5M at this time, still very happy with my X3M. I really like the G80 - awesome car. I want a Brooklyn or Oxide Grey AWD G80 Comp.

The value of the kit is incredible especially if you DIY - the kit + alignment puts you just over 1k and transforms the car. Even if a shop does the work, it is worth it. Props to MSS and RG_Sport for the development work.

Yes thanks to RG_Sport, I got my fronts replaced and it’s been perfect since. No noise, squeak, nothing. Agree with your assessment.

Thank you for the shoutout.

Y’all with an older X3 and on older software should consider an update.

Like the F8X M3 further updates that came on newer MY’s got improvements. An update allows older cars to get the same behavior.

I just did mine (with special tools) and the car is vastly improved including damping.

The key is getting the dealership to agree to update the istep. Not an easy process at most dealerships.

A software update improves the suspension??

Yes, it can be quite significant.

Care to explain the mechanics of how? I'm picking up my X3M next week so will review then

The software changes the behavior of the adaptive struts. BMW doesn't put much time into developing the actual suspension components (in my opinion) - most of the work is done fine tuning the software.

Finally got mine in over the weekend. Need to get an alignment this week but from the short drive I took I would say the rear is noticably softer, and the front is marginally softer. I have the updated front springs and sofar no noises of any kind. Now I just need to decide before my alignment if I want to keep it at the low setting (20mm rear 5mm front) or raise it up 1/2'' or so to keep my wife from nailing the front bumper on a curb.

Nice!!

Good morning all,

I have a very simple question. I will have the MSS spring kit installed soon on my competition x3M and I would like to know if I can directly adjust the settings to the lowest? I want a very aggressive look

Not sure what you mean by "directly"...if you mean right off the bat, yes you can set the fronts all the way down but then you'd have to match the rear to be at least level. Otherwise, if you set both front and rear adjusters all the way down, the rear would be lower than the front with the revised springs I believe.

Thanks, and thanks again for the springs, the tech support, and extremely quick shipping

[tarmactrr]

Also figured I would post this for anybody who is interested.

This is at 5mm gap on front and 20mm gap on rear on the spring height


According to the alignment tech, the camber on the front is not adjustable, so I was basically stuck with the left front being out of tolerance by .2 deg. The rears are adjustable, but I ran out of adjustment at 1.4deg. That said it was within the acceptable range.

After the alignment I did a short sprinted drive and am very happy at the handling of the springs. Still has very responsive turn in and mid corner stability, and feels a bit more planted when dealing with mid corner bumps.

Edit - I should also add the rear toe is at the minimum allowable because I asked for the reduced toe in order to try to help with tire life.

I do find it strange that the front springs make the car essentially sit up higher at the same spring perch setting. It makes it where you can drop the rear of the car about 3/4in lower than you can drop the front.

Not sure if that was the issue with the original springs too, or a consequence of the revised springs.
