Thank you all for the nice comments!
It would be a lot easier to buy the 5s fenders ! But in my eye they don't look right, I want them to follow the tire as close as possible.
And i have raised the wheel opening so the tire is in right place with the car lowered. And then i also have the front panel 80mm more vertical than oem to flow better with the lowered back panel
Its possible to do on the original 5s fenders but almost more effort than making own fenders.
