Need For Speed: Payback - 3 Stars On Dusty Trail Speed Run 

This video highlights how to achieve 3 stars on Dusty Trail on Need For Speed: Payback.
It personally took me over quite a few attempts, but eventually managed to achieve the 3 stars while driving a fully upgraded Porsche Panamera Turbo. I also had the suspension very stiff, power steering heavy, and grip balance at the rear under the live tuning (Press down on controller).
I hope this video helps as this speed run is a nightmare!
