Have a google at van pics in your colour and see what you like the look of. Everyone has different preferences and if you ask 100 people, you'll probably get 100 different replies! You will need to make sure your wheels and tyres are load rated for the model of van and then based on the width and offset judge whether you're happy how far in (or not) they sit. It's a bit technical, but there is a lot of great info on the forum and calculators. I have a t32 and did find i was more restricted in choice.
I went for Wolfrace Wolfsburg GTR Racing Carbon 18s - not that pricey. They have a width of 8.5J and offset (ET) of 38. Tyres, I went for Falken AZENIS FK520
255/45/18 103Y (I needed that load rating for a t32).
My van is also lowered 90mm which is a bit too much really but l love the look. You can see how that spec of wheel sits in the arches.
Have fun looking...just be aware it might take you months to arrive at a decision!
