Wheel Alignment Adjusting Values

The following values apply to curbweight according to DIN 70020 (car with full fuel tank, spare wheel and tools) From tire contact surface to 173 + 10 mm** may only be affected by replacing steering arms * The vehicle alignment settings are applicable to the actual vehicle ride height only (see repair manual pp. 44-1 etc.) ** The height setting values apply to new vehicles. Used vehicles may be up to 10 mm lower, i.e. the tolerance may deviate by minus 10mm. This must, however, be the same for...
