How to select aftermarket wheels?
i assume the fit is ensured if exact specs are used. The OEM MB for the GTS are
1. 19x9,5x112 62ET with s 66.6mm Center hub
2. 20x11, 5x112 68ET with a 66.6mm Center hub.
If the offset is different, must spacers be added to ensure there is no rubbing?
If the wheel is not OEM , must hub centric rings be used?
If choosing a wheel with same size dimensions and bolt pattern, must the offset be manipulated to approach OEM?

If the offset is different, spacers will only DECREASE the offset. If you choose a wheel that has a lower offset than stock, it cannot be brought inboard to fit like OEM.
Some non OEM wheels are made to fit to be hubcentric with our cars. You may not need a hub centric ring depending on which wheel you buy.
If you find a wheel that's the same size and bolt pattern, there will be some room to play with in regards to the offset. The rear has more than the front. There's no hard rules to what will fit and what won't. Tire size will affect this as well.
Assuming you're running stock wheel widths and stock size tires, for the front you can likely get away with a 19x9 +49 to +62. For the rear, you can go with a 20x11 +48 to +68. Some of those lower offsets will look odd if you don't lower your car. You can go with higher offsets but the wheels will sit more inboard and it will look weird. Also, if the offset of the wheel is too high, you'll need to consider if it will fit over our large brakes.

I have nothing but very high praise for Signature custom wheels. They are custom made to your specs; fully forged; lightweight; super strong; look great and cost about half what wheel from many other high-line manufacturers. If you’re interested call and talk to John Gaydos at Autoquest. He’d be able to help you re:sizing, etc.

Check with this. I have used this simple tool successfully a couple of times to buy rims. Never missed. Keep the -overall- diameter the same (unless you will reprogram the diameter for the traction management systems). Best is to center the wheel on the hub but sometimes it is used to offset to the outside deliberately to get that "flush mount" look. Dunno. If you go too crazy you will stress the suspension components unnecessarily. It is hard to tell what is too much.

In my opinion, start with choosing a reputable custom auto salon or custom wheel manufacturer. Query them as to whether they have experience with custom fittings because the GTR is a limited run car unlike an M3, etc which would be much easier to spec. Tell them what you want and they will make it happen without you running issues with improper fitment. You could just find wheels off the shelf on your own but you definitely don't want to run the risk of shelling out cash for wheels that you can't end up using.

This one is right up my alley!
1st-forget all the spacers, centering rings, etc, get a wheel built right for the car to begin with.
2nd-many companies (usually that sell cheap wheels you don’t want anyway, along with a couple higher end companies which is surprising) don’t do a good job with proper offsets and sizing, so buyer beware.
3rd-sent you a PM in effort to assist in the process for you.
