CHECKING AND CORRECTING HEIGHT
- Load down car to normal position*.
- Measure actual height (A) from wheel house lower edge (1) to rim flange (2) at center
of wheel height. Determine the mean value of each wheel after lifting and lowering
the car body, and then the mean value of the axle.
- Determine any deviation from the nominal height value*.
- Identify the installed springs - see 31 33 100.
- Find correction spring in the table. The numbers are height deviation (nominal values
in mm) between the pertinent springs.
Example:
The car is equipped with coil springs having BMW No. 1 126 024 and is, for example,
7 mm (0.275") too deep due to so many optional extra equipment parts. The nominal
height is reached by installing springs with BMW No. 1 127 662 (see 31 33 100 for
determination of part numbers).
Informations:
Thick spring ring for coil springs with red stripe.
Thin spring ring for coil springs without red stripe.
The height can be adjusted additionally by ± 5 mm (0.197") by exchanging these spring
rings.
