F30 M Sports Suspension:

[petrivanzyl]

I'm a bit confused after reading some threads on bimmerforum / f30post (mostly US posts)

They claim the F30 sport line in US includes "passive M sport suspension", "active M sport suspension" is a possible extra and they are debating which is best or if the upgrade is worth it.

As far as I can tell there is no such thing as "passive M sport suspension". From the F30 brochure I can only find

"M Sports Suspension" (SA704) R3450 - "vehicle lowered by 10 mm and stiffer spring/damper setup (not with SA2VF)"

and

"Adaptive M running gear" (SA2VF) R10900 - "features electronically controlled dampers that adapt to both driving style and road conditions, operating characteristics can be adjusted via the Driving Experience Control button, suspension lowered by 10 mm"

Neither of which are standard on sport trim. Is it possible that the specs in US are different or are they just smoking something over there?:fencelook:

sometimes you get different specs in the usa and europe.

noticed that with the vw's,and have seen a us spec rear bumper on a golf 5

Unless in the US they mean:

Active = adaptive...being able to lower the car by 10mm.

Passive = variable...being able to change the suspension settings without lowering the car such as sport and sport+ modes.

Old thread but I'll add my 2 cents.

Standard sports suspension is passive. There is no adjusting of the suspension settings via any manual controls or automated electronic / hydraulic systems (controlled via sensors).

'Adaptive running gear' is semi-active in nature. Only the dampening force of the damper / shock is effected, via both user settings ('sport', 'comfort' etc) and then the systems which adapt to dleiver the intended result. I'm not sure if each wheel can have a different damping force to the other, or if it's a global application.

Active suspension is far more complex, expensive and difficult to maintain / service and is therefore found on more exotic cars. The system adjusts in real-time for not just damping forces but height adjustment, individually to each wheel.

Wikipedia: "As the computer receives and processes data, it operates the hydraulic servos, mounted beside each wheel. Almost instantly, the servo-regulated suspension generates counter forces to body lean, dive, and squat during driving maneuvers.

In practice, the system has always incorporated the desirable self-levelling suspension and height adjustable suspension features, with the latter now tied to vehicle speed for improved aerodynamic performance, as the vehicle lowers itself at high speed."

Hi,has anyone installed the ACS suspension on a F30 m sport.
I would just like to see if the difference to stock is very noticeable.
