I need to know, what's the difference in 924S half-shaft (the rear wheel bearing is around it, can't explain better... ) and wheel hub compared to early 944.
Anyone?

I believe the 924S's half-shaft is longer than the early 944. The control arms are also longer, when I did my suspension swap to a 924S I had to get CV's(half-shafts) from either a 924S or a later 944 because of the wider track they introduced on the 944 in 1985.5 if I'm remembering correctly.

"Half shaft" is commonly used when referring to the drive shafts that connect the gearbox to the wheels - PET calls them "drive shafts". They call the end pieces that attach to the wheel hubs "rear wheel shafts" - some call them "stub axles".
The 924S's rear wheel shaft is a 951 part number and there's only 1 ball bearing assembly. -While the early 944 uses a 477 part number along with a series of spacers and 2 bearings. 924 5-bolt and early 944 use the same rear wheel shaft and bearings.

Thanx Smoothie, I meant wheel shaft but didn't know the exact match in English for that

I have mounted late-944 alloy rear arms and longer drive shafts on my 931, but I'm going to use regular (early-944) rear discs and I need to change the wheel shaft. If I can't MAKE the 924-944 wheel shaft+hub to fit, I'm going to buy 924S ones from friend of mine.
I got the whole late-944 suspension+brakes+15" five-spoke wheels for 300$.

The stub axles/wheel shafts, and wheel hubs are different parts on the 924S/951 vs the early 944/931/924 (with five-bolt and steel trailing arms).

The wheels lugs are longer on the 924/931/944 wheel hubs since they are used with the 20mm spacers, and the cost of installing shorter wheel lugs is high. It is less expensive to buy used 924S/951 wheel hubs.

I have late 944 wheel shafts+hubs (which are the same for 86-up 951), but using them will result in too wide track. Car is right now with them, and with current wheels, the 205mm rubber just barely fits under rear fenders.
Since I'm going to use 10J18 five-spoke rims from 993 in the rear (offset 40) and 8J18 in front (offset 52mm), I need the rims to be a LITTLE bit more inside, equaling about 40mm each. Using steel arms results in using big fat spacers which is not what I want.
Anyway, I'll take them apart and maybe I can let my genius guy in the shop to machine them shorter a bit. Of course, only if I cannot make the regular 944 wheel shafts+hubs to fit.

I was under the impression that there are two different sets of alloy arms, the 924S/'86 951 arms and the late 944/968 arms. Are they physically the same arms, with the difference being in the mounting or the hubs?

Yes, the arms are same for all models, same for drive shafts. Hubs and wheel shafts are different.

BTW, did you guys know that rear (maybe fronts too) arms are manufactured by Kolbenschmidt? At least to me this was a surprise.

The Porsche Technical Parts books show that there is one set of alloy arms for the cars (at least up through 8 originally built with alloy rear trailing arms (924S/944/951) unless the car has ABS or ABS and M030, or M030.
