Just noticed this thread..
Yes the Craft Square TC-F mirrors will fit both BNR34 and ER34, same bolt pattern. The quality of the carbon fibre is excellent, and they look very nice Most of the SuperGT cars use Craft Square mirrors. Visibility and field of view through the mirrors is great, never had any issue.
I'm picking up my car from the shop Monday, so I'll take some close up pics if anyone's interested.
