944 Rear suspension differences information

[Michael Ghia]

I've just done some measuring of the 3 different suspension and brake setups which come on the 944.
I found out the following.
Note...We already know that the difference between the mounting face on a 4-stud Beetle drum to an early 944 (pre '85) disk is 24mm... i.e. if you were to put a wheel with exactly the same offset and width as a Beetle wheel.. it would stick out 24mm further.

(All measurements were eyeballed up from springplate surface to wheel mounting surface (i.e disk)... so may be out by 1-2mm)

From the early 944 rear suspension to the first (narrow track) ally arms. There is a difference of 23mm.

From the early (narrow track) ally arms to the late (wide track) ally arms there is a difference of 30mm.

So from am early setup to the late ally arm setup... there is a difference of 53mm!

Add this to the 24mm from Beetle drums to Porsche disks and you end up with 3 inches per side! That's a lot of width!

Hope this helps with your projects.
