I went out and checked my 2014 stock nismo rear sway bar out of curiosity since it's up on the lift anyways, not that it's exactly relevant to OP's question.
It definitely depends on where you check, in the absolute center of the sway bar where it makes the big bend around the driveshaft I was getting about 26mm but on the straight sections for example next to the endlink it was 27mm.
