Here is my setup sheet from ROAR Nats this past weekend at APEX. Some changes with this setup, as I was using a locked diff for the first time and also have been working on trying to fix the trait where my car has a bit of a pause between mid and exit corner.
I ended up qualifying and finishing 7th overall in mod 1/12. Had hoped for a slightly higher finish, but traffic and other incidents didn't go my way in the 2nd and 3rd mains.
Let me know if you have any questions!
