Three stunt sets count toward GTA V 100%, and each needs only part of the full set. You only need the whole lot for two achievements, Show Off and Close Shave.
| Stunt | Needed for 100% | Total | Full set reward |
|---|---|---|---|
 Stunt Jumps (25 of 50) | 25 | 50 | Show Off |
 Under the Bridge (25 of 50) | 25 | 50 | Close Shave, with all Knife Flights |
| Knife Flights (8 of 15) | 8 | 15 | Close Shave, with all bridges |
How to complete 25 Stunt Jumps for 100%
A motorbike is the best choice, as it is fast and small, and an ATV works on dirt ramps. Elysian Island has a lot of jumps close together, so start there and add the airport and La Puerta. Some jumps only count if you land in the right place, and “Not good enough” tells you that you missed it. Use Franklin’s ability to line up your landing. Stay away from jumps 1 and 43 if you do not want a wanted level.
How to complete 25 Under the Bridge challenges
A helicopter is much easier than a plane, and a small one like the Buzzard fits the tight gaps best. Trevor is the best pilot, and any character improves with Flight School. The Los Santos River and the La Puerta canal hold 21 bridges between them, and you can fly them in a line, so that is the quickest route to 25. An on-screen message confirms each one, and hitting a bridge or its supports may cancel the attempt.
How to complete 8 Knife Flights
You must use a plane rather than a helicopter, and the wings must be vertical as you pass. Learn this in the Flight School lesson of the same name first. A nimble jet makes it much easier. Pillbox Hill holds five of the 15 flights, and with West Vinewood you already have seven of them, so finish with one in Del Perro. Line up early and hold your height with the rudder.
