RS Model

The following text only describes points which are different from the 911 Carrera. Details of alignment measurements on 911 Carrera vehicles are given under Standard Model.

Differences for Carrera RS

- Changed settings, refer to Specifications. Specifications





- When driving onto the platform, additional ramps, such as those needed for the 959, must be used.
Otherwise, the front spoiler (arrow) would touch the ground.
Platforms without inclination are not suitable.
- Depending on the equipment used, spoiler adapters with lengths of 50 or 100 mm are required for the sensors of electronic wheel alignment testers.
Without these adapters, data cannot be transmitted from the right to the left.
With the wheel alignment testers recommended by Porsche, which have a special spoiler test program, 100 mm spoiler adapters are needed for the rear axle.
Check the operating instructions of the wheel alignment tester.
- Adjusting height of front axle:
As with the 911 Carrera, the height of the lower spring mount is adjustable.
How ever, the Carrera RS has an additional lock nut.





- The height of the rear axle can be adjusted using the adjustment nut(s) on the spring strut(s).

NOTE:
- On the 911 Carrera (993), the spring struts must be removed for rear axle height adjustments.
- Different shims must be positioned on the upper spring retainers.

- Max. wheel load difference left/right on front and rear axle 20 kg;
Same as for 911 Carrera.
- Setting rear axle camber:
Same as for 911 Carrera.

NOTE:
- In order to obtain more camber (up to - 3° 30') for racing use, the slot in the side part near to the camber arm is longer.
- To allow a greater adjustment range, the stroke of the camber arm has been increased by 2 mm.





- To adjust the kinematic toe-in change on the rear axle, the stabilizer must be removed.
- The vehicle must then be lifted until control arms 2 (track arms) are about horizontal using an axle lift unit positioned at the center.
This is essential for installing and reading the levels.
- The setting procedure itself is the same as for setting the kinematic toe-in change on the 911 Carrera.





- Setting front axle camber:
Same as for 911 Carrera.

CAUTION:
- The racing camber setting available on the Carrera RS must be used only on the race circuit.
- The spring strut mount can be set from normal (as shown on the drawing) to racing camber.
- Three bolts and nuts (no. 1) and two slots (arrows) in the upper part of the mount are used to change the camber.
- The camber is increased by - 1° 30'.
- Fine adjustment by ±20' is possible using the slots.

- After adjustment and assembly work, check all wheels for free running.
