Stock Ride Heights?

[we350z]

What are they or where can I get this info? Would anyone with 20" rims be able to measure for me?

In real world how much will (front comfort)springs sag after 18 years? I'd like to lower my rear bags to compensate.

Found this in another thread. I believe they are in MM

Thanks that.

I've always thought one of my rears was a bit higher than the other but wasn't sure if one was high or one was low - now I know I have one rear that is ~20mm too high (on 18" rims, at 720mm)- now I need to find out why!

I saw those measurements too but was hoping to corroborate them.

Where does one measure from and to? I have a laser measure but not sure how I can use it...

Bottom of the rim (near the ground) to highest point on fender arch - vertical measurement.

I am happy to measure mine for you but I am on sport package coil springs.

Got it.

Just wondering - if my fronts are lower than the specs listed in the table due to spring sag is it safe to lower the rear by an equal amount?

At what point lowering rear only will one experience ride issues / start to look funky? I've read that lowering the rear too much can change the suspension characteristics (camber?) enough to cause premature tire wear...

Measured mine:

Rear Left - 730mm
Rear Right - 733mm

I'm not sure what tire pressures should be used with 20" rims I think that would only slightly affect the measurements.

Sounds like might be a hair high but 10mm is not much variance. Pretty negligible difference.

I wonder if the system uses the good sensor reading for setting both air spring heights
If one sensor becomes inoperable...?

Look at the sticker on the driver side door frame.
Sound like you need to do a ride height calibration.

Nice Z32! Is there any good documentation on this procedure. I think I need to do one anyway since I have new-ish bags and a am replacing my rear driver/left side height sensor when I do my brake job.
