I got my 2013 Nismo clear bra'd the first day I had it- only way to protect but you would do that before you get rock chips...
I got the hood, full fenders,sideskirts, roof, front bumper and lip, headlights, doors, full rear quarter and top of wing. No lines either most is all wrapped.
I did this as my 350z when I went wider and lower offsets I started noticing chips on the rear quarter panels and lower doors and sideskirts. My 350z did have front bumper, headlights and fenders clear bra'd though.
Now I'm full protected
