I'm pretty sure the mk3 beam is wider than the mk2. Depending on your tires I think it's ok though.

Want to say you're right.  Either way, the MK3 rear spindles will go on the MK2 axle just fine, as will  just the discs. You can use a 16V Scirocco MC for 9.4", or the Corrado MC if you go 10.1" fronts.  The reason is mostly to prevent the rear discs from locking up due to the amount of fluid the stock MC's drum circuit pushes.

ive been to the yard today and ive found a 97 Jetta GT with rear discs on it.  (the only mk3 in the yard that doesn't have drums).  

I will have to return on monday morning with a spade so I can dig down enough to remove relevant brake stuff.  Im assuming I can use this 97 stuff on my 86 without too much difficulty.

Question, are the spindles between the caliper and drum identical apart from the provision for caliper bolt holes?  Does anyone sell these stub axles new?  I have searched and only found the drum type stub axles

EDIT-  Autohausaz has the caliper specific stub axles for around 60 bucks apiece.  Might go this route rather than dig up some rusted POS stub axle instead.

Tyler, have you added this to the FAQ thread or no? some good info.

How much of an upgrade are you looking for? And what kind of upgrade are you looking for? Are you hill racing this thing? Driving like a dickhead and need more "OH %&#*#*" stopping power?

I might be one to think too big of a brake might be a very bad thing, in some ways. Much less weight so they will lock up a whole lot easier.

A good vented 9.4" setup will stop a turned up AAZ with rear drums quite adequately. I see that you've got an 85 GOLF, have you motor swapped? Is it still non-turbo? 9.4" solids will do more than fine for that car.

I daily an 84 Jetta (2150lbs with me in it) that has a more than stock powered AHU engine, it has 9.4 solid rotors up front and 180x30 drums in the back. It stops more than adequately.

Not trying to rain on the parade man, I am just giving you some real world experience.

I have not added it to the FAQ, go ahead.

Another situation where larger/vented brakes would help is if you do a lot of mountain driving, or if you tow. Also if you drive on the 401 ::)

Alright I will.

I would go vented first, and then maybe the next time it needs brakes.. upgrade to a bigger size.

mk3 is MUCH wider...

4" wider than the mk2 rear end..

i dont see it possible to swap a mk3 rear beam into a mk2, and still run tires, without hitting your fenders..
92 Jetta GLI - Black, 1.6D w/ GT2056V turbo..
86 GTI - 4 Door, Med Twilight Gray, Tow Machine..
86 Audi Coupe GT - Tornado Red, All Stock.. WRECKED.
89 Toyota 4Runner - Dark Grey Metallic, LIFTED!

Turbo: exhaust gasses go into the turbocharger and spin it, witchcraft happens and you go faster.

for me personally, its twofold, one lots of crowded freeway driving.  (another upgrade im considering is a pair of additional brake lights on the rear deck.  You get rear ended once, you get shy, and after all, the mk2 is still a slow beer can compared to most other vehicles on the road)

2nd, i find calipers cleaner and easier to service/inspect, I hate dealing with rusted out drums full of brake dust.
