I can't give you numbers, but here's a photo of an HPN Rallye Sport mid-build. To my eye, that looks pretty close to dead center. If not, it's still definitely less than 32mm. I know they give you different engine spacers to move the whole engine and trans over to the right a bit which reduces the offset. What further modifications they do, I'm not sure.
This what you get when you just bolt it all together (I think I stole this photo from Lornce):
