Unique Stunt Jumps, or USJs for short, are strategically placed ramps/stair wells situated across the map. When your vehicle hits the ramp at an adequate speed, the camera view adjusts to 'cut-scene mode' and, upon successful landing, the USJ is completed, and you will be rewarded with £250. If you do not execute the jump successfully a 'Unique Stunt Failed' notice will pop-up. At this point, it is time to take a further run-up, or get a faster vehicle. There are 30 USJs in total, and they need to be completed for 100% completion. Use this map to see where they all are:

Tips:
• A new feature for not losing track on what extras you have picked up and passed and which ones you haven't, has been introduced to the game. By holding down X in the pause menu map, you can choose to display exact locations on the map of the red balloons, rampages or unique stunt jumps you have found and burst/passed with are represented by icons.
• One jump has to be done in succession, No. 4 to No.5. You must jump onto to the building via No. 4, and stay on the building to do No.5 (on the rooftop of King Knuts). This particular jump is easiest using a sports car, like a Banshee.
• If a car doesn't do the job, use a motorbike - the PCJ-600 has always been the best for unique stunts.
• Push the analog stick forwards and backwards, if you're on a motorbike, to shift weight and gain greater speed.
• If you can't find the ramp (or whatever it is you're going to jump from), then search for a staircase as it will most likely have to be taken from a rooftop.
• There are three stunt jumps; 21, 22 and 27, which must be completed using a JetSki or a fast boat.
• Take as long a run-up as you can, even if it means starting in the middle of a the road amongst the traffic.
