Download link: WorldSBK 17 version 1.4
Installation: The pack includes bikes, paints, stands and tyres, just unzip it in: X:\Program Files (x86)\GP Bikes\gpbikes
Remove the "bg" folder in: "C:\Program Files (x86)\GP Bikes\gpbikes\misc\
Important: Delete old versions (tyres, stands, setups and bikes) for avoid cores. An advice:
LAA (large address aware) now is not more optional online, because the tracks and bikes are more detailed with many and big textures, without it the core.exe (when the memory exceeds 2GB) online are possible. Just download e run it for use more 2GB ram with 32 bit .exe: LAA Link
