Its worth noting that Sprinters in Europe come typically with 15 inch wheels - so that isn't probably a good option in Europe then.

The brochures I could download on both the Swiss and Austrian MB website seem to mention 16-inch wheels, with 235 65-16 being the typical tire size.

I should have said that better - the European sprinter's with 5 lug rims (up to 2006?) came with 15 inch rims. I think they the switched to 16 inch rims with the 6 lug wheels in 2007. Not completely sure...

Correct, 6 lugs on the recent Sprinters... sorry I should have checked before posting.

Was able to do a test fitting of a Euro-type Transit 16 inch wheel on the disc brakes - it looks like they will require the same thickness of spacer as the Sprinter wheel and so will require an "adapter" type spacer (i.e. one which uses the stock lug bolt to attach the adapter and then has five additional lug bolts for the wheel to attach.

The outer edge of the Transit wheel appeared to be at the same position as the outer edge of the Sprinter wheel - so a very reasonable amount of offset in my opinion.

I was able to test fit one of the Ford Transit wheels with the disc brake conversion using an adjustable spacer I improvised. Looks like they will work very well with only a small increase in the spacer thickness compared to the Sprinter wheels (about 1/8 inch or 3/16th of an inch).

Here are some (not so great) pictures...

In this first photo the angle of the camera and the camber of the wheel with it in the air while up on the jack make it look like the tires stick out more than they actually do - the edge of the tires tread is actually even with the outer edge of the wood rub rails when the wheels are in a vertical orientation (i.e. with a small typical load in the Pinz).

Can you knock up some disk brakes for the front of my haflinger? After your great effort here, the haflinger should Easy Peazy.

I've considered it (I have a haflinger too) but I just finished a full rebuild of my brakes...

Haflinger is so small, light and slow, plus there are so few of them - it would not really be worth it.
Would be a fun project if someone needed something to do but I find Hafi brakes work very well.
Dual circuit would be nice but you can add that already

Yes...the stock braking system is my least favorite part of my Pinz, I liken it to the Pinzes Achilles heel...if a reasonably priced disc brake system could be produced for off road use of course!!!...I would be very interested in purchasing a kit

I am interested too - esp since I already have 2 correct spacers (from a different need).

I was just looking at the "Classic Sue" website and they had the following information about wheel spacers in Austria at least:

"The width of 29mm was chosen in order not to exceed the widening of 4% permitted by the Austrian legislature"

So the additional width for the disc brakes of 1 inch on each side (<26mm) should be compliant at least in Austria when using the Sprinter wheels.

Here is an image of their wheel spacer:

They also sell one for the Hutchinson bead lock wheels:

I don't see why everyone is so hung up on transit wheels. For guys in the U.S., why not just get a wheel adapter. For around $300 you can get them and then you can use any wheel you want. Ford, chevy, jeep whatever bolt pattern. Custom wheels any rim size, offset etc.

I don't personally like them in general because:
Cost
Possibly more bearing wear
Possible body clearance issues
Dealing with taking it off to service a hub
Can also be a weak point overall

And the look of most aftermarket wheels. especially US versions, just don't fit exotic Euro 4x4 styles, in my opinion.
