I'm about to buy 18 inch wheels for my 1M (winter and ring)
Your post is very interesting.
Can you tell me if the dimensions are good?
I love knowing that absolutely maintain the same allignment than the original. (same side of stock)
Front: 8.5x18 ET20
Rear: 9.5x18 ET20
p.s forgiveness for my English ... I am Swiss and live in Switzerland.
