APR questions. Yes, APR 350 BBK fits under 17x9s Apex without spacers. I run this, see pic for my VS-5RS forged 17x9s. Someone was running them with the flow formed SM10s as well in the same size.
If you need rotor rings, APR/Arin has stated that they will continue to be able to be sourced and yes, Powerbrake should be able to get them. Hit up Delon w/Powerbrake USA:

Pads are a standard size, easiest is to search by 2018 Subaru WRX STI w/Brembos...that's the shape. There are others. These brakes are great. The APR "Advanced street/entry-level track day" pads are my daily pads (similar MOT [1166 deg F) to something between Carbotech/G-Loc 6 and 8s) and I've tracked them..just wear faster on track. I have their "Advanced track day" pads for track use (similar MOT [1472 deg F] as Carbotech/G-Loc 10s), they are fantastic but too much $$...I'll move to something else next time.
