I don't say this very often about cosmetic modifications, but WOW! the silver vent slats are a GREAT touch! I think everyone should try this--it kind of ties the 986 in with the 987 a little bit too.
But, that bottom section where the vents are connected, I would've masked off the flat section so that only the slats were painted.
Regardless, it looks great, nice job! Now ditch the headlight covers.
