Mine is a Kombi and I am halfway through the process of renewing the bushes, bearings etc as well as fitting a stud extension kit and lift spacers, uprated springs and shocks etc.
Unladen (with the exceptions of an extra spare wheel, spared seat and some tools plus a rear mounted ladder and wheel carrier I have just measured the rear at 80cm from ground to arch with 20cm from tyre to arch.
That's running stock wheels and tyres, stock springs and shocks, Syncro Services 20mm lift spacers and the rubber pad. I expect this to come down when I fit the Westy interior but when I fit the 16" wheels and 235/70R16MT Bronco's it should balance things out. I've had the rear arms modified with the flange folded down and seam welded to give extra clearance for the muds but even without spacers the 16"x8Jet11 Pentas clear wonderfully around the arm. I will post pics up when they are fitted to the van itself. I'm hoping to pick up some 944 CV joints next week to alleviate any binding problems at the rear I may encounter.
A few pics:

Wheels and tyres


The front end will be getting similar treatment with studs, bushes, bearings, 2wd HD (green) springs. The rear of the front arch will be trimmed a la 16" and Tristar arches fitted to finish them off.
