GC8= world market WRX 4 door sedan or RS sedan with an EJ20 swap would technically be one. 'G' means Impreza chassis. 'C' means 4 door. '8' stands for EJ20 engine.
Therefore, a 2 door 2001 RS is a GM6. 'M'=coupe, '6'=EJ25.
GM*=coupe Impreza
GC*=sedan Impreza
GF*=wagon Impreza
G*8=Impreza w/ EJ20
G*6=Impreza w/EJ25
G*4=Impreza w/EJ22 (not 22b)
G*2=Impreza w/EJ18 liter
New style:
GD*= Impreza sedan
GG*= Impreza wagon
G*A= EJ20
GDB= EJ20 STi (no GGB, since there is no STi wagon)
G*6= EJ25
STi does not get a chassis code modifier prior to the '04 model year. The differences between a previous world market WRX and STi come down to individual parts.* They come off the same assembly lines.
* Until 2001, with the introduction of the new body style, all EJ20s were pretty jammy. Same basics in the 'base' WRX motor as in the STI and even STi RA motors. Translation- they all made the same power with similar mods. STi owners didn't like that. So they complained. And Subaru listened. Now, the EJ20 in a WRX, the EJ205, isn't a whole lot better (though it still is) than a turbo EJ25. The STi motor, the EJ207, is pretty kickass. And even better than that, is the old EJ20G, which was the version 2-5 (I think) motor. Those motors would easily make 320 horsepower. Out of 2 liters. Wow.

My USDM 05 STi lists GD7 in the VIN (digits 4-7).
G = Car line/Impreza
D = Body Type/4 Door Sedan
7 = Grade/WRX-STi
So is GD7 my cars chassis code or not?
There is some duplicated information in the VIN (GD, etc), but the real chasis codes is labeled "Applied Chasis Code" on the information plate under your hood.
I don't know if they changed the code for 05 or not, but I believe the applied chasis code for the 05 is still GDB.

I wouldn't really say that there are advantages. For a specific car, you will need rims of a very specific offset, and if you vary too much, you can cause extra strain on your hubs and stuff (yeah, how's that for a technical answer).
How much offset you require is based on the car you drive, and how wide the wheel is. I don't know exact numbers off the top of my head (ask in the Tires and Wheels forum for a better answer) but, most Subaru's want 48ish to 55ish, depending on how wide the wheel is.

Yeah, then you have a GDF.
G = Car line/Impreza
D = Body Type/Sedan (specifically Bugeyes and new generation, not first gen Imprezas)
F = Grade/WRX-STi (is it F for '04 and '05 STi? I'll try and find the answer tonight)
