In my opinion, 22mm front and oem 2017+ 15mm rear bar is a great setup, especially if you don’t want to use a lot of front camber, I’ve had 20 16 on stock 2017+ setup (showa base shocks not sachs) and while I liked the front when I put the rear I didn’t like the balance of the car, even on the softer setup, but I think it’s also a matter of tastes
