Just do the wheel arch screw mod. ET45 to ET50 fits perfectly.
Why my alignment?
1. I want more wheel/suspension travel
2. I need more ground clearence for coming winter
3. from the view of performance a slightly lower rear feels better
4. I never carry more than one passenger or any heavy goods
5. it looks much better to me
Some guys run 345 mm front and 325 mm rear, so much more difference.
