>>Hu? These photos are from a Vanagon front axle! You didnīt had a look at

>Wonderful, that's really good. I've never had a front wheel off my T3! In
>fact I only had the thing 3 months before the trans died on a trip to
>Christchurch, 365km north of here, and it's been in storage there for the

>>Iīll find out.

>Most appreciated!

>>Fixed calipers, 4 pistons, two inner and two outer

>Best braking, easiest to adapt. more good news.

>>If you donīt have an official paper confirming the strength and stability,

>>Testing, testing, testing, at least when going the VERY official way ;-)
>>under which circumstances do the adapters break etc.

>I guess it doesn't hurt to know what it takes to break an adapted rotor,
>but i won't have to do that here. whet they MAY do is take the van for 5
>immediately-consecutive crash-stops from 100kmh, to see if the braking is
>strong enough and fade-free. The present brakes won't pass that test. I'm
>surprised they didn't do the test when the 3.8 V6 was fitted by the PO,
>but perhaps that regulation only was drafted later.

>>thatīs what they did on the photos. A new center with 5x112mm

>Was the center part of the kit, or did the owner have to have it custom-made?

>>Yes, both version have the bearings/hubs combined with the rotor. Even the
>>stubaxles are the same because old and newer vanagons use the same bearings.
>>>
>>> The South African (RSA) Caravelle has a different hub with a removable
>>> rotor. I believe the axle (spindle, stubaxle) is the same as the later
>>> German one.
>>
>>As far as I know, they are the same. But tno need to change because of the
>>vanagonīs age (same bearings as mentioned above)
>
>Good news.

>>Hansen provides new hubs where the porsche rotors with 5x112mm center fit
>>onto.
>
>Excellent (though I bet their pricesare excellent too... from Hansen's

>>I attached a few Oettinger rear bearing housings where the caliper mountings

>The one time I tried to contact Oettinger (about their wasserboxer-6s) I

>>>So... I either need to:

>>Like our idea above. You could built an individual porsche rotor center to

>This becomes a problem if I ever want to return the vehicle to stock for

>>So every adaptation, Porsche, oettinger, our own ones, are based on the same

>I guess it's the simplest easiest way.

>Well, many thanks for all this. You have answered even some questions I
