80q b4 2.2 20vt project

Just found those 8A0407615B hubs, but outch, that +10mm offset will not gona work with my wheels.

Rear hubcarriers with hubs for 82mm bearings should be searched from 80 B4 Avant. I have seen even 2.8 Saloon US version with 82mm bearings at rear. Such hubcarriers are not very rare parts in my place (compared to any S2 parts which are just impossible to find)

Rear outer CVs from B4 Avant and S2 Avant/Saloon are the same: they have 38 outer splines and 25 inner splines.

OEM 4x108 hubs for rear 82mm bearing have following options except native ones: front 80 V6 hubs 8A0407615B (+10mm offset each), front 90 B3 7A hubs 893407615F (+5mm offset each).

8A0407615B are very easy to find, 893407615F are not.

Thanks Jim

I got a sick idea of buying A4/S4 big 38 spline hubs and fill weld the 5x112 pattern and rebore to 4x108(as I don't wan't to buy new wheels and fronts yet.). Then machine off a little bit from the hub bearing surface and fit BMW 42x75x37mm wheel bearings.

Part nr. and link are few post up.

Bought a pair of 2.6 avant hubs, carriers and driveshafts, but didn't receive the driveshafts because seller thought CV joints are busted and threw them away

Does someone know are the rear shafts same size/thickness/splines on 75/82mm and only difference is the CV joint or not?

[Kiku]

Well thats something new for me.^^

Rear driveshafts under b4 q chassis for 82mm housing are only available on S2/RS2 avant/sedan. Not even B5 S4 has them.

As I said before some V6 avants on B4 also have 82mm/38 spline hubs and carriers in the rear.

You have welded center/rear diff or everything is stock there?

[M2ki]

Hubs are custom made?
Crazy expensive, in front he can use C4Q rears as he already has 82mm housings and in the rear use S2 82mm hubs and carriers, prices seems to be 200-300€ for a pair.

Just checked my parts pile and I have a pair of hubs and carriers from 2.6 avant and they are 82mm and 38 splines, so maybe it is avant thing.

[Thuppu]

Ok, so this is from Avant, and has 38 tooth spline... Hmm..

[M2ki]

Yes there is 8A0501653C

[Thuppu]

Hmm, seems that saloon and avant has different part numbers. But then there is 4x108 and 5x112 hubs for both versions. So is there a 4x108 "big" hub available?

[M2ki]

Bearing size yes. I thought that 2.8 came with 82mm bearings and 38 splines.
