Need for Help 2015

Hi guys, I’m not here to take your reviews of this liked or hated game.

I’ve encountered little bug I think. I bought a GT86 (same problem on FR-S and BRZ), I want to install and see for the first time the Greddy and the two Varis front lip. But it said that they are restricted. So I try with all bumpers, and all body kits but don’t work…

If someone have a solution?
