Soo after the last 20 inch post is forever ago I would like to present here my chassis / rims combination to the question what fits and where you have to work to clarify! So I have Eibach 30 mm springs in connection with Sachs Advantage Dämfern and all crossbars, sockets etc. installed and me from MS Design the MS18 8×20 ET45 (normal for the Ford Focus,Kuga,etc.) and in black gloss powder coated. With respect to the tires: 225/30 R20 is not enough due to the 85ers load index! So I had to go to 235/30 R20! after some problems with the HA regarding stripes I had more concerns that when the tires are fully impacted the inner Kotflügel diss….. Mhm… so I risked and see there: front and back no problems! So I do not know any FWD vehicle and assume that the AWD is a little higher. Vl. an advantage. Whether you can transfer this experience to the S40 / C30 I can also leave some of them with the screws!
