Since v0.1.25-preview12 of Shaders Patch, my configs here seems to be officially included (much appreciated!) (you may also download them from https://github.com/ac-custom-shaders-patch), which meams you may skip step 2 below if you're using the latest versions.
Shaders Patch - Dynamic Lights 0.1.23 or later needed.
*NOTE 0.1.22 NOT SUPPORTED ANY MORE
2018 Formula RSS2 V6 added
1、copy the .zip files to assettocorsa\extension\textures\cars\rss
2、copy the .ini files to Documents\Assetto Corsa\cfg\extension\cars, *now you may skip this if you're using the latest versions (0.1.25 pr12 or later) of Shaders Patch
Major credit and thanks goes to @davewilliams000 and @formulaHEINE for their Tire Packs for Formula Hybrid and Formula RSS 2 respectively.
