Hi all. Haven't managed to find any thread where it's specifically said which are the maximum size allowance for standard arches in a K11 super s. Based on your experience, what width and offset are ok to fit exactly within the arches? I'll be running either 13" or 14" so I am basically after the right combination of width and offset. I suspect that 14x6 et 40 would still sit too much inside. Suggestions? Thanks
