Boxster (987) F6-2.7L (2006)
Self-centering quick-clamping holder
Receiving surfaces for the quick-clamping holder on the wheels and the adapter surfaces must be clean and flat. Always check the leveling surface on
the wheels precisely in particular before fitting the quick-clamping holders.
Strictly comply with maintenance intervals for measuring equipment and measuring platform. If the leveling of the measuring platform or measuring
station is done in-house, leveling equipment is required. A spirit level is not adequate.
Skilled handling of measuring equipment and measuring platform.
Sliding plates with transverse motion (rotary motion) at the rear axle are advisable.
Observe the Technical Literature of PAG, the manufacturer of the measuring equipment and the manufacturer of the measuring platform.
Do not treat measured values as a whole, but very critically with regard to driving dynamics, high-speed strength of the tires, tire wear and cost/benefit
effects (time required for correction of insubstantial deviations). The toe values are of decisive significance for driving dynamics and tire wear.
If the vehicle is measured front and rear, check and adjust the wheel alignment values at the rear axle first. Camber values at the front axle apply for
the straight-ahead position of the wheels. Steering wheel and steering gear in center position when toe is being adjusted.
Before wheel alignment values are adjusted at front and rear axles, it is recommended that the vehicle height be checked at the DIN empty weight.
Conclusions can then be drawn about wheel alignment values in the event of any suspension alignment that becomes necessary later.
Aligning vehicle at front and rear
Vehicle height (height check)
General
The vehicle height at front and rear axle is not adjustable.
Preliminary work
For the height check, place the vehicle on a level surface or on the measuring platform (ready to drive, with a full tank and tools but without driver or
additional weights). Compress (push down) vehicle at front and rear axles 2-3 times and allow it to spring back freely.
Front axle
From road contact surface to hexagon-head bolt of cross-member screw connection to the body.
