911 Targa (996) F6-3.6L (2004)
-
rear right D and front left A decreases
The wheel-load difference from left to right on front and rear axle should be as small as possible (under 15 kg if possible).
Vehicle height 911 GT3
General
The vehicle height on the front and rear axle of the 911 GT3 can be adjusted.
Before wheel alignment values are adjusted at front and rear axles, it is recommended or necessary* that the height adjustment be checked at the DIN
empty weight. The height adjustment possibility allows the wheel-load difference from right to left to be kept as small as possible, provided that wheel
load weighing machines are available. The wheel-load difference is adjusted by changing the vehicle height within the height tolerance. The priority is
to achieve the smallest possible wheel-load difference from left to right.
* after work which causes a change in height or in the event of an incorrect height
Note!
^
The height adjustment possibility allows:
1. Differing wheel loads on left and right to be corrected. At the correct height the wheel-load differences lie within a permissible range, provided
that the coil springs have the same installation position (installed spring preload) on each axle. Tolerance ± 1 mm. Wheel-load differences can be
kept as low as possible in conjunction with wheel-load weighing machines. Tolerance from right to left on front and rear axle under 15 kg.
2. Any impermissible height differences - front axle to rear axle - can be balanced out (only within the permissible tolerance).
Preliminary work
For the height check of the ready-to-drive vehicle (full tank and tools), place the vehicle on a level surface or on the measuring platform.
Front axle
Measure from wheel contact surface to the lower edge of the hexagon-head bolt of the tension-strut screw connection to the body (Figure 74_99).
