Thanks so much for sharing this! I have a 2015 base. I'm sourcing the F Sport bumper parts now. Would love to see how you assembled the F-Sport bumper.
Miss the G content. I bought the exact same car, a 2003 black on black 6-speed sedan, right when you got yours because someone totaled my 6-speed Maxima. Can't get rid of her. Just installed a new rebuilt 0-mile VQ engine. In love all over again, heh.
A FWD version (weighs 200lb less than the AWD and with less driveline loss) running premium 93 fuel (increases power and fuel economy) will feel much quicker than yours.
