There are a total of 40 Vehicles Stunt Rings found in Pacific City. The best way to do this is get to at least a level 4 Driving Skill so that you have the Agency Buggy, Agency Super Car, and Agency SUV.
There are multiple ways to do this:
- Do it yourself and jump through every stunt ring with a specific vehicle.
- Have a coop buddy throw you through some easy stunt rings. Some of them are either to far of a distance and you must do them yourself.
- Grab a helicopter from the Agency Helipad and have your friend be in a Agency Buggy. Use two Mag grenades and magnetize the helicopter and Buggy together. Fly around as the vehicle goes through the stunt rings.
