944 Rear suspension differences information

[Wally]

Michel,
I have 993 wheels and the rears are indeed 70mm off set but are not 9 '' but 8 '' x 16. Fronts are 7 '' x 16 and have an offset of 55 mm. I use the late (994 turbo) arms and with an spacer of 1 inch and inner and outer widened Kerscher wings, the wheels aline exactly with their tire walls with the wing sides.
Hope this adds to your info (and for others doing this mod)
Walter
