Direction et braquage

924 all markets / 931 US+Canada+Japan
Steering ratio: 19.15:1
Turning circle: 10.08 m
Track circle: 9.21 m
Turns, lock to lock: 4.02

931 ROW (option for US+Canada+Japan)
Steering ratio: 22.39:1
Turning circle: 10.3 m
Track circle: 9.5 m
Turns, lock to lock: 4.02

924S/944 manual rack
Steering ratio: 22.39:1
Turns, lock to lock: 3.84-4.02
Turning circle: 10.75 m
Track circle: 10.1 m

924S/944 power rack
Steering ratio: LHD 18.85:1 / RHD 18.96:1
Turns, lock to lock: LHD 3.24 / RHD 3.26

 

So I don't see any benefit of hassling with the 924S rack if you can find the optional 931 rack. For reference, the 924/931 racks all have the same part numbers, but different suffixes:
478 419 061 C: most common, in all 924/931 except RHD 924, ROW 931, and optioned 931
478 419 061 A: RHD 924
478 419 061 B: optional 931 rack

So if you can find a "B" rack, you'd get the same 22.39 ratio as the manual 924S/944 rack.
