Steering and Suspension: Description and Operation

Front axle/steering





McPherson wheel suspension with offset spring. Twin-tube gas-filled shock absorbers in standard or sports version.
In order to obtain greater stiffness with reduced intrinsic weight as compared with steel, the following components have been made from aluminum: Control arms, diagonal brace, track rod, wheel carrier and cross member / side member.
Rack-and-pinion steering gear (i = 16.9 : 1) with hydraulic assistance. Steering wheel longitudinally adjustable (40 mm).
Further improvement of steering precision and reduction in the turning circle (10.6 m) as compared with the previous 911 Carrera (993).

Rear axle





The multi-link rear axle used in the 911 Carrera (993) served as the basis for the further development in the new 911 Carrera (996). Important considerations here were to achieve further weight reduction while preserving the familiar good vehicle dynamic properties. The longer wheel base offered additional potential for improvements in driving comfort and handling.
The wheel suspension consists of five aluminum control arms, of which the two upper control arms are aluminum forgings.
Gas-filled shock absorbers in standard or sports version.

Brakes





Hydraulic dual-circuit brake system with front axle / rear-axle brake-circuit distribution. Vacuum brake booster, internally ventilated and perforated brake discs with four-piston monobloc fixed caliper at front and rear axles.
ABS 5.3 (3-channel system) standard. ABS/TC 5.3 (4-channel system) on request. TC = Traction Control, consisting of ASR (anti-slip control) and ABD (Automatic Brake differential).
Parking brake (Handbrake): Drum brake acting mechanically on both rear wheels.
