Hello sl-fans, how are your experiences in the conversion from 18 to 20 inches wheels? my r-230 is 30mm deeper and with the 18 inches for me a good compromise between optics and comfort. has someone experience how it looks like when it is converted to 20 inches with the optics, the distance to the wheel cutout is more noticeable, because there is significantly less rubber on the rim with the same roll circumference? optically the gap should not look bigger, since I find it at 18 inches still ok,or looks at 20 inches even the wheelbox even more filled out, how are your experiences? lg alex
