Those are the factory 07/08 fender trim pieces. To add the gills he’d have to custom fit them and cut up the fenderId replace those side vents with legit Tiburon gills. They are timeless and much more aggressive those side accents look like they belong on another car.
Then on to the spoiler. Id really like to see someone pull off the classic supra rounded one. It's something you never see everyone when making show cars gets a huge wing it's very played out not original at all.
I would look into a paint job as well. Two dark colors kinda bounce off each other the dark blue color(which I love) just doesn't accent the carbon very well imo. A lighter color would make the mods pop out more right now they kinda fade in the background.
