I have BBK on my g37s and i was selling the car. Someone wanted to swap mine for his out. He doesn't have Sport brakes/ calipers. would his non sport brakes, rotors, and calipers fit my car? I know people usually have swaps from non sport to sport brakes but im not sure about this.

 

Yes, the small brakes will fit an S. But why would you do that? It'll hurt your resale value.

 

That'll be bad mojo if you try to trade or sell your G37S without the big brakes, not worth the bad karma that would come with such a tactic IMO.
