3d objects materials for assetto corsa

[B3NW3LL]

Hi I'm new to making tracks and have 2 tracks that you can download and try.

I'm looking for help in adding extra objects and materials to my tracks if anyone can point me a direction to download extra models and textures would be great or even share the ones you have, I have quite alot of xpacks and could do with some more.

So if you could help that would be fab, Thanx
