I have had a pair of 15x7j wide 5 solids made up.
These are not banded but professionally rerimmed wheels and are infinitely safer than banded wheels. They are original wide 5 centres welded into modern VW rims.
The back space is pretty close to stock so the extra 3" is all on the dish.
£200 a pair add £15 for postage.
They are located in Staplehurst, Kent
