C30 7.5/8J x 18-inch Which ET fits without reworking?

Hello everyone, I drive a C30 D5 with AEZ Xylo 7.5×18 ET43 with 225/40-18 tires. This went without rework and it grinds nothing, although I also have a 30mm lowering. Now we will get another C30 (D3) and are looking for 18-inch rims for this, which I fit with 30mm lowering. Unfortunately, the Xylo will not be produced more than 18inch and I don’t like the Ronal R41 so much. At 8×18 ET45 I find only rims with runs. I would be interested here whether someone drives an 8×18 ET45 rim or a 7.5×18 ET40 rim with 225/40 and has got it removed without rework, although it is something in most reports. And if what rims have fit with you with which tires? Here is a typical edition K42 on axle 2 by reworking the wheelhouse edges a sufficient free-accessibility of the wheel tire combination.
