Can air suspension be stiffened or better upgraded with anti roll stabilisation

Having run my 7 seat g05 with the mandatory air suspension for the last few months, i’ve Realised the ride just isn’t for me. Before swapping out for either one with 5 seats and upgraded m-sport suspension professional or for the new sq8 vorsprung (with upgraded suspension) that I test drove yesterday and fell in love with...... does anyone know if my existing set up can be improved as it’s a fabulous spec car to give up but I just don’t like the drive - and before anyone asks yes I have changed the setting to sport plus which supposedly makes it stiffer but it makes little difference and is still pants imho.

Have asked my dealer who’s no idea and have Also asked AC Schnitzer and Hamann but as yet Havent an answer.

If anyone can enlighten me i’d Be very grateful before making a decision to stick or twist.

Many thanks in advance

What don't you like about the air suspension?

I just ordered the 2 axle air suspension on a 2020 x5 m50i. Did it provide a smooth ride?

Ride in a straight line is fine - cornering the roll is awful tho at any sort of speed. On a 30d it might be fine but a 400bhp diesel car that won't corner at speed? To me it's not good enough - it is smooth yes but it needs better roll stabilisation so after 6k miles I'm getting rid which is quite a hit!

And that's why air suspension is the basic set on the 30d and 40i models..... higher performance they use coils as standard clearly for a reason so I'd stick with that unless like us you need the 7 seat option.

You may think different but I'd compare all 3 suspension options first before ordering. If I had there's no way I'd have stuck with air - M-sport suspension professional (a 3k option in the uk) is what I'd like but it's not an option with third row seating.

I had the exact same experience when test driving a 7-seat 30d m-sport with 20". The cornering is like driving a bus or boat. Tried a 40i m-sport with AS, same experience. Luckily the BMW genius suggested us to try another 7-seat 30d m-sport with the performance package which comes with 22", we're so happy with the outcome and that's exactly what we're looking for, comfy but not sacrificing handling. I strongly suggest you to test drive one with both AS and 22".

Thanks but the 22inch wheels are standard with the car so am already driving it like that ..... it's going into BMW tomorrow as can't believe it's not right. If they can't fix it I'm getting rid as it's dreadful cornering don't you think? Even with air pressure increase to the max.
On a 30d with less power it might be better to live with but it's woeful on the 50d with 400bhp. So much do I'd say it feels dangerous.

same feeling here with my Air suspension.....to floaty and when you switch to sport or sport plus there is little difference.

Hope BMW come up with an improvement via software update. At least to make it firmer ins Sport plus

This is the inherent problem with your air suspension. To make it stiffer you need more air which raises the. Try the +10mm option and see that it is stiffer.

To solve this you would have drop the car and put more air in the bags, all while making sure everything operates normally.

This might not be possible.

Came back from the main dealer today and all they confirmed was the ride heights were slightly out so they corrected.

No feedback offered on whether the dampers can be stiffened but have promised they've asked Germany the question.

Technician admitted it's floaty - even in sport - and agreed the handling isn't what you'd expect on a top of the range m-sport model.

I'll speak again with the suspension specialists who think they can lower the car - and with a reduced centre of gravity maybe it'll improve.

Ideally I'd love to see the car run at the lowest setting as it looks mean as but don't think anyone's cracked coding on how yet.

Guess BMW quickly need to develop roll stabilisation like the Audi sq8 and 7 have on their Vorsprung model air suspension - the g05 it's simply a comfy cruiser until then and whilst quick in a straight line - cornering quick simply isn't possible with confidence or without feeling you're on a fairground ride.

Highly disappointing.

Ride heights appear to differ between 20mm and 25mm as attached.

Lowest setting I'm guessing is another 20mm off sport. The stance looks great when parked - need to over rule the self correct.

So Hamann have launched a product which would lower the centre of gravity..... will certainly look better but whether it handles better in corners remains to be seen.

Any one tempted?

I'd also like the arch extenders 23" wheel and front lip spoiler but eye watering costs!!
