Try the RDD True AI Mod, its the most comprehensive so far.
Before you drop it in though, back up the original catch up file somewhere
From there you can adjust it by, either by putting back your catch up file you backed up, and/or adding the AI Slow corner fix mod.
I would also suggest adding the 25% damage mod, as you will then see a few more DNF's from the AI.
(Ensure you then have damage turned on to full, and do not crash yourself ...lol)
