Photos of Error404 from 'for sale' section, I hope he does not mind.
7A ACOQ rear shafts. They are shared across many non-turbo ACOQ-s (ABC,AAH,NG, NM) and 5-cyl 90 B3. 33 inner teeth. 30 outer teeth.
Aproximately 535 and 502mm from what can be seen on photo.

Good thread

Sorry for bringing such an old thread back up but it’s very hard to find information on driveshaft length.
Does anybody have the length of S2 coupe rear shafts? I have a pair but the difference in length is more than I was expecting and I am having issues fitting them. My set up is far from stock so it might not be the shafts that are the issue. I was surprised how different they are compared to fronts which are much closer in length.

Few posts up.
Aproximately 535 and 502mm

That’s says non turbo cars so are we saying the S2 coupe shafts are the same just with a 108mm inboard cv joint?

[M2ki]

Should be, as the rear axle geometry is the same. Same diff, same subframe, same hub carriers. Spline count and thickness maybe different.

[Kiku]

Spline count is different. Thickness is the same as 7A can vouch for that. Possibly 2.8 and 2.6 as well.

Rear driveshafts from Audi 80 B3 typ89 Quattro saloon with 4 cylinder engine. Partnumbers of shafts assemblies with joints should be 893501203H and 893501204H according to catalogs. The cat claims they are also from Audi Coupe Quattro typ89 KV/NG.

509mm left, 551mm right. 33 inner splines, 30 outer splines.

S2 coupe rears 545mm and 503mm

[Colesy]

Does anyone know which way around the front shafts go? ie the longer one is which side?

[LukasR]

I am not 100% sure but from my informaton driver side is shorter;
51.7mm uk driver side
53.1mm uk passenger side
this is dimension for bare shafts
