Some time ago i came upon an extensive setup guide for grip and drift setups. It is written for real life use, not simulations. The grip setup guide is divided in 8 parts and the drift guide currently has 2 parts. I hope you will find it usefull
Tip: each part is written on several pages, so don't miss the other pages and read the first page only like I did
btw this guide is written by the same guy who works on Dai Yoshihara's s13
