Wheels and tyres - Alternative wheels
Introduction
Please read disclaimer.
NB. Warning... When fitting alternative wheels at the rear, please note that unless they are recessed for the two small drum locating set screws, then they will need to be removed so the wheel can be pulled up flush and flat to the drum surface.
See here for wheel nut & bolt torques

Where suitable I have added notes on work needed to fit them.

Notes: Good choice of usable offsets, centre bore adequate.
Sprinter wheels require Porsche adapters. ML wheels require spacers, particularly at the front due to offset.
Reports coming in that ML wheels use the 14mm ball taper standard.
