I went with Martian wheels, 18*8,5. With slightly bigger 245/45R18 tyres. They look awsome, it's a ET28 rim, whichis a little wider than stock, combined with the fatter tyre, looks really good.
Ride comfort compared to the stock 20" PS4S is excellent, quiter, more comfy, steering is more precise, but still very confident at high speeds. Also 10% less energy consumption on average. I went with Pirelli Cinturato All season Plus tyres, which are a little heavier, didn't look at the tyre weight unfortunately.
