Just got the 16" OEM hubcentrics (X40867) from JRP in Mississauga yesterday with Hankook iPike409 in 205/55/16.
Andrew was great in doing the install and the tires were already mounted on the rims so the whole process took about 20mins. Good conversations too!
The rims are X40867T - not so sure they are Subaru OEMs but they have been primed and painted black (Krylon paint) from the original silver so I'm good with them. He mentioned that they were port take offs that were provided to them from their distributor. They are hubcentric and fit well.
So far the wheels and tires are performing well - no vibrations and some regular winter tire noise. I will say though that the car is definitely more floaty mostly because of the winter Hankook iPikes. Waiting for the snow now! But wouldn't you know it'll be 5 to 13C this week with just rain
