Two of these in 8.5" with an ET of 52?

I bought these in Feb, and due to the offset, they won't fit on the front of my GT TDI as they are 9's. But they look the shizzle on the back.
So, what I'm trying to say is, does anyone fancy a swap? Two 9's for 2 8.5's.
I'll do all the tyre changing, as I have all the gubbin's at my disposal.
