Do I need spacers on a 2023 Porsche 911 GT3 RS?

Only if a wheel's offset sits above ET55, the top of this car's accepted range: a spacer of (offset − 55) mm brings the face to the edge. Of 1 listed wheels that pass, 0 sit above ET55; the rest are inside ET25 to ET55 and need none.

01Listed wheels above the range (spacer arithmetic)

None.

Spacer arithmetic only. The car's accepted range ET25–ET55 comes from the fixture; a wheel already in range needs no spacer for fitment.
