Vehicle Height/Wheel Loads
Information
- The vehicle height on the front and rear axle of the Cayman GT4 can be adjusted at the spring struts .
- Adjusting the height means that different wheel loads on the left and right can be corrected .
- At the correct height, the wheel-load differences are 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. Right to left tolerance on rear axle less than 15 kg, on front axle less than 10 kg. Target: rear axle: max. 10 kg/front axle: max. 5 kg .
- To check the height of a ready-to-drive vehicle (full fuel tank and tools, washer-fluid reservoir full), place the vehicle on a level surface or on the measuring station .
- Nominal values: → 4X00IN ADJUSTMENT VALUES FOR SUSPENSION ALIGNMENT .
- Adjustments should be made with the axle raised. Taking the load off the wheels makes it easier to make the adjustment (adjusting nuts on the spring strut are easier to turn and will have no signs of damage) .

Basic information on height changes/wheel-load changes
When changing the height/wheel-load, the following must be noted:
- A one-sided height change causes a wheel-load change at the same time. A wheel-load change on one wheel also alters the wheel loads of the other wheels .
- A one-sided increase in the installed spring preload (raising vehicle) increases the wheel load .
- A one-sided decrease in the installed spring preload (lowering vehicle) decreases the wheel load .
- A change in the wheel-load is always transferred diagonally onto the other axle side. This means that if the wheel load on one wheel is decreased or increased, the same occurs on the diagonally opposite wheel .
- Example: Rear left spring preload is increased. As a result, the wheel load: rear left -C- and front right -B- is increased - - - - - - - rear right -D- and front left -A- is reduced - - - - - - - .
