This is just a solution for one PR Stunt but it was the hardest one and was killing me. Ended up smashing it with one tip. It's still using the Formula Drift Dodge. However, everyone is saying gear 3 for all the drift zones. This worked for me on all except S-Bends. Use gear 4. In gear 4 I got 94,253 first attempt heading downhill (South to North / East to West). I used Tiptronik's Drift Zone tune. Manual (GEAR 4), ABS Off, Traction Control Off, Stability Management Off, Steering Normal. Braking line may help you know when to brake more on the bends. Remember, you can use rewind before it comes up FAIL. So use that to your advantage if you make a good 25k+ first turn.
