If the centre bore on the rear is different then I'm guessing the fronts will be the same. I can't see Audi making a car with different centre bores front and rear :*

T4 centre bore is 57.1

If the centre bore of the wheels you want is bigger then simply get spigot rings- about £4.50 a set off the bay.
However, if centre bore of the wheels you want is smaller than the T4 then you will need hub adapters, about £180 I do believe. And then you need to think about the ET (offset) as the adapters will add approx 20mm poke.
If it were me, I would walk away from wheels with a smaller bore than the T4's 57.1 as there is plenty of choice out there- unless the wheels are uber rare I: x

Sounds like good advice lucky I had the chance to try them same lovely set of rims for the price So it seems 112 OCD is ok but you need to look for centre bore as well so what does fit straight on

Audi A4's have the 112 stud pattern, 57.1 centre bore and ET 35-45 approx (except the allroad)
T4's have 112, 57.1 and ET 30-50 approx so they should go straight on in theory.

If the bore is greater than 57.1 then they may have been bored out.
If smaller, they may have spiggots already fitted?

Might be worth getting the exact model they came off.

Off set on the allroad is 15-25 but bore should still be 57.1.

I don't think I'd recommend boring out of wheels but I'm sure it's possible with some.

also check the pcd...

as some audi come with 5x100 pcd

audi also has a 57 centre bore,most vw is 57.1

if the wheels where realy special or rare,genuine rims,then i would look at opening the bore slightly...very easily done by a skilled engineering shop....but otherwise leave them...
