Cars Help with adding reflection on F10 texture

[Cimmerian_Iter]

Hello guys, I'm porting the Ferrari F10 model to assetto corsa found on sketchable

Sketchfab

skfb.ly

The problem is after converting it in kn5, the color red is just red, there's no reflection and it doesn't look as nice as any F1 car on assetto.

How can I add reflection to the car?

Thanks
