Well after searching around all morning, The soonest I could acquire a replacement kit was Monday.

I gave a call to Patrick(G3tR3DDY2GR3DDY) and he said he had the right rear caliper. So I drove the 2 hours to his house to pick it up.

Got everything installed, went for a short test drive, checked over everything, went for a longer test drive to embed the pads.

As of right now, the brake pedal has a softer initial pressure, but once you get passed that, it bite's hard

That's because the pistons/pads back off the rotor a bit more than OE which results in less drag at with a bit of softness taking up that clearance before they clamp down again

No to your first question, and no to your second question.

Edit: RB does make an aluminum caliper to fit the OE rotor, but it will not fit behind a 17x9 +45 RPF1.

it's not so much the offset as the wheel spoke placement/design

Some of the Enkei wheels also have a small inner barrel diameter near the spoke attachment area

Ok, thats correct it is smaller ID at the spokes.

So no go for this ones.

I tested some 4 pot brembo this weekend I had lying around, they are original from a Alfa Romeo 166 V6 3,2L.

Fitted almost perfect, only would need a adaptor to fit but will it be worth the trouble? they where ~1kg lighter.

will be around ~330whp when the car is finished and im afraid the perfectly good (for ~200whp) stock brakes wont be up for the task. really would like to stay with my RPF1 17".

Guess its up for testing when my car is ready.
