It was clearly mentioned using annotations and pictures of the IRL car and the in game model - that the side air intake trims are gloss black composite - while the front grille trim below the headlights and the front splitter are matte black - just like the rest of the vehicle when observing the side skirt and the rear diffuser.
The front splitter has not been fixed as it is still glossy and silver after the update. Loos like afterthought conalted to the rest if the vehicke’s ground effects.
Requesting to fix the front splitter on the Dark Horse and correct it to matte black.
