Here is your hat, Mark.

If you'd bothered reading the post you'll notice I say +12kg of saved weight. Not per wheel, but all round.
Instead you chose to make a prick of yourself. Well done.
As I've weighed Sebrings at 9.3kg I was allowing 3kg difference per wheel.
Do try and keep up with the other adults.
I have Team Dynamics rims on my Golf. They come in at 6.6kg each, but that was a compromise of cost, weight and strength, so if I'd gone just for low weight I'd have been able to score rims weighing in at 6kg each.
In my experience the ~3kg per wheel makes a big difference to the handling and steering feel.
