5.8 General Instructions on the Modification of Standard Vehicles
Attachments with high centre of mass
At vehicles with high attachments or with a raised overall centre of mass, the driving conditions are limited.
Stabilizer bars are used to prevent excessive heeling of the vehicles.
The following table shows which centre-of-mass height is permitted for vehicles with standard equipment. These heights must not be exceeded. In addition, the table shows for which vehicle variants stabilizer bars or reinforced stabilizer bars are recommended.
The maximum permitted centre-of-mass heights indicated in the table may under no circumstances be exceeded.

Centre-of-mass height specifications according to directive 71/320 EEC Since 01/01/1991, all utility vehicles must comply with the requirements of the "EC Directive on Brake Systems, 71/320/EEC". The adoption of this EC directive into German traffic registration regulations (StVZO) results in a situation in which these technical directives must also be fulfilled at single acceptances (trial runs).
