wheel sizing on 280z with flares?

[chmercer]

hi guys. i am trying to figure out wheel sizing for a friend. I dont really have any proper measurments so the offset is probably gonna be +- 10mm. so if you have any sizing info, please let me know. here is what i have come up with so far.

 

judging by my 240sx (s14) the stock wheels were 6.5" wide +40 offset; I am able to run 9" wide with -1 offset on mildly pulled stock fenders. so that comes to about 74mm wider than stock. my friend has stock wheels and weve already pulled his fenders (probably even more than mine) so this measurment should be close, if not too small even. On top of this, he was looking at either these flares (are these called IMSA flares?)

or the ZG flares.

 

does anyone have any exact measurments of these flares? just eyeballing, i guess that the IMSA ones are 2.5-3" wider than stock? this would constitute another 76mm of wheel offset (at 3").

 

Finally, guessing that the stock wheels he has are about 5.5" wide with about 5 offset, that would mean, with the flares, in a 10" width, for the wheel to be flush, the wheel would have to be about -90 offset

 

So I am thinking this would be 10" wide with a 1.5 - 2" inch backspace. not totally sure. but does this sound correct to you guys. thanks!

I think the user name for that Z is Speeder, and he post the mod on his web site too.
