Do hub centric spacers matter since the rpf1 has a 73mm bore? The rotor is 65.9mm so no spacer will fit the new wheel. But obviously I can get one to match the rotor. It's way cheaper to just buy a flat spacer with long studs.

Hubcentric spacers for the hub with hubcentric rings on the spacer to fit the wheel bore is the ideal method. That's what I did with mine. The hub rings are so cheap that they are worth it in every scenario. The hubcentric spacers are more expensive though. Still a good peace of mind.

Ahh never knew that. Ok so rotor is 65.9ish but doesn't matter because ill be buying spacers made for my car so I know they'll fit. Eibach for example says the bore is 66.10 ID. Obviously they will fit with a 0.2mm difference. But what's the outside bore that fits into the wheel? Would that be back down to 65.9 like the rotor? I found rings 66.05mm ID, 73mm OD. Seems to close since the wheel is 73mm.
