235-40-17 front and
275-40-17 rear... aftermarket of course.
17" front due to BBK, and 17" rear due to lighter and cheaper than 18's.

That might be true on some application. But some lightweight wheel with tires combo will be lighter in 18" size. The extra rubber the 17" has usually is a tad heavier than the lightweight metal.
The folks at RouteKS did a comparo with their ZAZ NSX-R on a 17/17 CE28N combo and a 17/18 CE28N combo at the 16th Running of the Tsukuba Super Battle hosted by Rev Speed in December of 2005 (It's their 3rd year in a row participating in the event, interesting to see that they chose to run with the ZAZ NSX-R in the NA (Naturally Aspirated) category instead of their widebody highly modified Zero-Force NSX)

With the 17/17 setup their best laptime was a 1:01.73 with a 17/18 setup their best laptime of 1:01.77 so the difference on that particular track was negligible between the 17/17 setup and the 17/18 setup.

If you don't have much track experience - say, fewer than a dozen track events - then I recommend using whatever tires you are using on the street - whatever size and type of tire. You won't be using anywhere near your car's capabilities, so there's no need to worry about it.
Once you start building up a lot of experience, then you'll probably want to consider making the jump to R compound track tires, and get a separate set of wheels to use. At that point, you'll want to consider what type and size of tires you want before you buy the wheels. Track tire availability varies depending on the tire size (and, of course, wheel size).
I'm using R compound track tires (now Toyo RA-1, formerly Yokohama A032R) on the stock 15"/16" wheels in the stock '91-93 sizes. They give great performance, much better response than street tires for track use. They also fit inside the car, so I can drive to the track on my street tires and swap at the track. And you can get used sets of the wheels for almost nothing ($100-200 per set). However, those wheels cannot fit on the '97-05 NSX or earlier NSXs with big brake kits.
With both brands of R compound track tires, heat cycled but not shaved, I'm typically finding that they last 1300-1500 track miles plus another 400 street miles (between the track and the hotel). Unlike with street tires on the NSX, the fronts do NOT last 2-3 times as long as the rears.

I'm running
Front: 215/40 17" Bridgestone RE55s
Rear: 265/35 18" Bridgestone RE55s
The front tyres are only available in Japan. They are made specifically for the NSX.
I have to import them specially.
