Early 944 NA are the easiest to fit.
The rears bolt on (ie calliper bracket fits to the Beetle trailing arm and hub fits one beetle stub axle, just a bit of fiddling to make the handbrake work (either new cable with the Porsche ends or make a new clip for the beetle end to hang onto).
The fronts require the 1303 pressed steel arms and a Kerscher ball joint. The ball joint fits into the beelte arm and fits the Porsche steering knuckle. (Beetle ball joint stub is too small to be clamped by the Porsche knuckle). The 944T ones have a bigger ball joint again, so the Kerscher one won't work, and the backs I think have a different bolt pattern as well.
The Porsche knuckles have more positive camber on them so you need more adjustment than the stock setup can give you to bring it back. Topline sell an inner bush for the control arms to do this ("camber +" kit). You will also need 1303 / golf (mk1) / 944 front struts. Golf are the shortest.
The setup adds a reasonable amount of track to the front of the car so to get the wheel to fit under stock guards you need rims with an offset of around 50mm
Then you need to fit up the Porsche master cylinder because the front calipers are too big for the Beetle master cylinder to push enough fluid, otherwise you end up with a very poor pedal feel. This is also bolt on (same bolt pattern) but a little bit of clearancing required and some new brake lines to extend the originals to get everything fitted up.
Then you end up with very average feeling brakes on the street, and after a few laps around a track (once things have warmed up) they feel fantastic!
Thats my experience anyway. I've got some photos

I kind of wished I'd gone a different way, more like what Steve C has, only use the ford rears and some 4 pot fronts over a Beetle hub with vented disk attached. That way you get to choose your stud pattern and much better selection of wheels, not just Porsche ones at Porsche prices, although you may have a better selection over there than we have here.

There must be some other options in Aussie? You guys have been racing beetles for ages, what do Vforce and those guys do?
Good luck
