^^I'm on a 42ET, 17x8 with a 7.8" tread width, 8.5" section width, 23.9" tall, 215/40 on them, on the factory suspension, and have PLENTY of room to spare.
I'd bet it would never rub even a little, during even the most conducive scenarios for it, on the Swifts, which lower in about that same drop range as the Eibachs.
