There are few differences between suspension alignment on the new 911 Turbo (996) and suspension
alignment procedures on the 911 Carrera (996). This involves the vehicle height adjustment, the wheel−load
difference from left to right, special tools and corrections to wheel alignment.
Modified quick−clamping holders are required for the 911 Turbo (996) (to fasten the measured−value pickups
on the wheels). The quick−clamping holders present can be retrofitted by replacing the clamping units on the
left and right. Supplier: Messrs. Beissbarth. These converted quick−clamping holders can also be used
retroactively for the other Porsche models. The order number for the new clamping units will be included in
the Workshop Equipment Manual.
