You can do that. But, that’s why you measure from the lower rim lip. So that different tires don’t affect ride height.

4.8is Ride Height Calibration

Sorry to bring up an old thread, but if I have deleted air suspension for lowering springs and dampers. What do I set the ride height to in INPA. Do I change the default to what I measure? Or do I change the range/deviation to reflect the height it sits at now?

Most of the replies here are regarding lowering via factory air. Just trying to recalibrate for new ride height.

INPA will show you the default height measurements for the type of suspension and wheel size.

Then you measure your current height and see if you need to raise or lower compared to default height and enter difference.

But you deleted it so I'm sure its of no use.

You could of just lowered to your liking it with this method if you kept the air suspension.

I personally went to 1/2" lower than defaults today.

So the ride height monitoring is strictly used for the active suspension. Nothing else. Not for the FTM or the active headlights?

Active headlights reference ride height to self/auto level. FTM/TPSM is not related to ride height. The measurements from BMW are taken from bottom of wheel to fender arch bottom so tire height (pressure) does not affect it.

Yep, as mr_robot stated, the ride height is measured (by the car's sensors...) as the difference between the body of the car and the axle (via the suspension arm). A flat tire doesn't change this relationship so the ride height cannot be used for FTM.

For those who tricked the car to go lower, when you press the access mode, does it now go even lower?!
