Removing and installing front spring strut - GT3: Installation

WARNING: This page is about a different variant/trim than selected.

Install in reverse order. Before installing, give the parts a visual check. Replace brake caliper fastening screws.
Do not grease screwed connections in Dacromet finish - aluminium colour. Use correct tightening torques.
1. Insert spring strut (A) as far as it will go into the wheel carrier (B). Before tightening the fastening screw No. 6, twist (align) the spring strut (A) until the stabilizer block is in the correct position with respect to the wheel carrier (B). The correct position is described in Point 3.2.
  NOTE:
  - As the installation conditions are confined, the correct position (fitting) of these parts is a prerequisite for adequate clearance of the stabilizer mount in the area of the wheel carrier/stabilizer block.

2. Correct position with respect to the wheel carrier means: The receiving bore for the stabilizer mount in the stabilizer block must be centered (aligned) with respect to the cutout of the wheel carrier (arrow). This prevents the stabilizer mount from coming into contact with the wheel carrier when the wheels are turned completely to the right or left.
  NOTE:
  - Contact marks are visible on the housing in individual cases. These marks are due to the incorrectly positioned stabilizer block (spring strut to wheel carrier). The stabilizer mount is not damaged, however. Stabilizer mounts with contact marks can be replaced if assembly is to be conducted in this area.

Place the wheel-carrier/spring-strut assembly into the vehicle.

Note the installed position of the spring strut mount. Outer side (A)/inner side (B). The shock-absorber piston rod is thereby shifted outwards. Use new fastening nuts. Before tightening the fastening nuts, adjust spring strut mount in accordance with the applied marking (position of the three collar nuts).
NOTE:
- The three unused bores in the spring strut mount are intended only for driving on racing circuits. The three fastening bolts (M8) are fitted in these holes in this case. This increases the negative camber.

Fit brake caliper on wheel carrier. Replace fastening screws. Tightening torque 85 N.m (63 ftlb.). Fasten holder for brake line/brake hose on wheel carrier.
NOTE:
- The brake caliper fastening screws - on the front and rear axles - are 5 mm longer with the GT3.
The screws are also different colors.

911 GT3 = red (77 mm long)

911 Carrera (996) = silver (72 mm long)
Fit stabilizer mount in center position (arrow) on the stabilizer. See Fig 5

Check and adjust steering-geometry values at the front axle.
NOTE:
- If assembly work was performed or parts replaced that affect the vehicle height, a complete wheel alignment is necessary.
