Well. Huffs were very well accepted on MK5 and people loved it. You will be astonished to know the brand new rim is about $400 each.
The interlogos plates seat design came from early MK1. It was so much loved and liked that they still have those seat design. The honeycombed front grill is another feature which is moving generation to generation.
As far as Golf R wheels. Those are 19" rims. Will be too heavy for GTI suspension. I love to keep car stock. Just slight upgrades are fine and I dont have $$$ for golf R rims. Scirocco never came to US so no rims here. And import from UK is again lot of money..,
