* Height adjustment settings apply to new cars. After cars have been driven for a period the height may be max. 10 mm less, in other words the downward tolerance can vary by 10 mm more. However, this must then apply to both axles.

" The caster angle value of 4' + 1* can be adopted retrospectively on cars back to the 1986 model year inclusive (from introduction of vertical ball joint at front axle subframe pivot / refer to Page 40 - 19), The caster tolerance range on the measuring chart should be modified if necessary. The printed measuring chart will not be amended until a new issue is printed.
