Racing grid and paint

Hello, I want to buy such a racing grid, quite cheaply at atu.de 😛 only when I looked at the front of the fox everything exactly I noticed you can not attach it to the standard front lip at the bad bottom at all. or about? because it goes yes nciht deeper to attach it. and as second question I have.. what would it cost below to have the black paint at a fox at the front lip in the color of the car. thank you already in the previous mfg.
