I prefer the EP3 over the FN2. My EP3 after 42k has no rattles whatsoever and I've given it some stick too.
The FN2 has better handling as its more sure of itself entering corners where in the EP3 I'm a bit cautious, but then that may be because the EP3 is my car
The FN2 boasts better brakes and an even firmer ride thanks to the new chassis but it makes the car feel horrible. You could add a few braces and add nicer brakes and have a great handling EP3 and the FN2 wouldn't touch it.
But the JDM FD2 is where it's at, I'd love to get my hands on one of those!
