Search for jasin s "sooty thread" gives lots of answers.Ive done the same conversion on my 80 tdi.Ball joint is the same outer cv joint is different.cant quite remember but i used v6(no quat coupe) shafts or just outer cv joints.To convert the rear to 5 stud use std a4(non quatt)rear discs.

Ok, five stud wheels on a four stud setup.
Decided at long last that converters just weren't going to happen. It could have been done, but at the expense of being safe in the knowledge that the car wasn't going to be overtaken by four rogue wheels that had just come loose from the hubs.

That means a five stud hub setup.
First hurdle is the rear, Can't use any S2 gear as it's FWD. I bought two rear five stud hubs from C4 Audi 100 2.6 FWD, they fit the rear no problem, BUT! I just could not find any info anywhere of a suitable rear disc. Wasn't going to start messing with looking at different rear callipers either.
Step forward user on here "Wolfgang" who showed his Coupe's rear setup further back in the thread. This route involves using 1995 - 2000 B5 A4 1.6/1.8/1.9 TDi FWD rear discs.
Beauty of these is that the disc IS the hub. The wheel bolts to the disc itself The same wheel bearings and rear ABS rings as the 80 TDi is also used on the A4. So all is required is the A4's discs, new bearings (two each disc, inner and outer) pressed in, new ABS rings heated and pressed on. That's the rear sorted.
Now the ballache that is the front.
This TDi uses 75mm wheel bearings ojn the front, the S2 front hubs press into 82mm bearings as we all know. So S2, 7A or 2.8 carriers would be needed. So you fit the carriers (no need for me to worry, my struts have 14mm bolts holes) but then my TDi driveshaft won't fit, too small as they locate into smaller wheel bearings. S2 driveshafts are a no go, this 80 is FWD, meaning unequal length driveshafts even if I fitted the correct flange on the box.
Bit more headscratching. Coupe 2.8 FWD shafts would work. IF I could find any.
Step forward MikeS2. He kindly located two 2.8 cq front driveshafts and I'm going to remove their outer CV joints and fit them to the end of my TDi driveshafts. Lots of extremely boring internet searching and cross referencing parts, have told me the end of my TDi driveshaft is 24mm in diameter and has a tooth count of 30. I've measured the size and tooth count of the 2.8 CV's and they match. The outer splines of the 2.8 CV match and fit in the S2 front hubs which were sourced from James (Spink).
New CV boots and a host of new bolts/nuts and washers also sourced.
Going to try and do this little lot of Sunday. Fingers crossed that my boring hours searching on the net pay off and the 2.8 outer CV;'s fit on the end of the TDi shaft.

AH, brakes. Mike also grabbed the G60's from the wrecked 2.8cq, BUT, as said earlier in the thread, I'm well happy with the brakes as they are now on this 80, instant bite and lots of feel, WAY more feel than the 996's on the S2 as it happens. Probably down to the "no bomb" servo assistance. They fade if really pushed, but this car isn't about being pushed to within an inch of it's life. It's about the mpg on derv and veggie oil and it's looks.
So, two new 280mmx10mm solid discs have had a 5x112 pattern drilled in them. Stock setup then remains.
