Which Toyota 86 trim approximates the FR-S?
 

just curious. Is it the G?

Definitely not the RC.

It's fixture... but need to decide, it's G

I think it's the just the G, but it has a radio.

It's between G and GT.
Rims: G = 16". GT = 17" like FR-S.
Gauge: G = all black. GT = Like FR-S.
A/C Control and Smart key: G = like FR-S. GT = Like BRZ Limited in U.S.
Fog lights: G = no fog lights like FR-S. GT = comes with fog lights.
Rear brake: G = not ventilated. GT = ventilated like FR-S.
Gas pedal: G = black. GT = Silver like FR-S.

And many more.

I got these info from Japanese Toyota site.
