Went with Sport Edition A9's 18x8 +35mm and 225/50R18 Blizzak WS80's. Test fit them today. Of course they took a little wiggling to get them on as I'm used to the extra room with 19" wheels. Clearance #s are guesses, didn't measure.
Front: Clears brakes by 1/4" on face and 1/2" on edge
Sticks out like maybe 1/2" past fender (forgot to take pic of that) but turns lock to lock with no clearance problems. Maybe 40mm offset would've solved this but it's fine for winter wheels.
Rear: Clears brakes by 1+" on face and 3/4" on edge
Tire sits flush with fender
Thanks for the help!
