The numbers I quoted are just mathematical. The only way to get exact offsets is to go with a custom built wheel. Otherwise, if +23 is the closest, go with that. It's only a 6 mm (1/4") difference.

In spec is misleading if someone wants OEM like alignment. Technically -1.4 front is in spec but that's a lot of camber compared to -0.6 stock up front. Handling is better and tire wear is worse.

Front camber kits push in/out the top of the wheel while rear kits push in/out the bottom of the rear wheels.

I would say knowing in advance if you are going to be running a camber kit would be useful for wheel offset decisions.
A bit of "toe in" can help with "scrubbing" the outer edges of the tire, and thus help even out the wear. Even at -1.4 (the inner limits of the camber range), you will be fine. It's if you run something very aggressive like beyond -2.0 where you need to watch how your tires wear.

Regarding your statement about knowing camber in advance and offset decisions...yes and no. Camber adjustments should be made to bring camber back to alignment specs (stock height or lowered), or if you want to augment the car's handling characteristics. Some people buy wheels with really aggressive offset and then add a ton of negative camber to get the wheel to tuck in properly. But really, one should buy wheels with proper offsets and keep the cosmetic camber adjustments to a minimum. If I may make an analogy (for fear of opening a new can of worms), you can buy a body kit and rear wing for looks, or for function.

Having said that, my camber settings are: -2.2 front and -2.0 rear. I wanted an aggressive street setup with more front camber to improve turn in response. These settings feel good both on the street and track so far.

My car is lowered by 0.75" front and 0.5" rear and is corner balanced. I also have 15mm front and 20mm spacers. After lowering my front camber was really out of whack (-1.0 and -1.6). Rear camber was around -3.0. I ended up buying SPC front and rear camber kits because the front camber wasn't adjustable with OEM parts, and they could only bring the rear camber back to -2.4 with the OEM components. When I was doing my research on the forum before lowering people were saying you don't need camber kits (especially front) if you go with less than a 1" drop, but that wasn't the case with mine anyway. However, some people don't mind being out of spec for different reasons, including cosmetic.

Nismofo...nice setup on your car, BTW!
