ANOTHER GLITCH!

if you spawn at the supply point in the cliffs of los muertos (forget what its called) and get in a car and drive toward the statue (wont be there if you already beat los muertos) once you get to a point the achievement will unlock for getting a car to a heigth of 115 feet so yayyy easy way to get an achievement

a way that is just as easy is go to the central point building in the chinese island(beat a boss on that building). It has an elevator. ride up the elevator in your car - bam - achievement unlocked. from there is also a jump off the top - bam - easy way to get x2 frontflip

That's a good one...hadn't thought of it. The way I got that achievement was by carrying a car to the highest part of the mine in Volk...but your examples are much easier.
Nice work everybody!

so they showed these on Cheat! the show on G4 and i was like woahhh but yeah they showed another way to get the car juggler is just pile up all the cars and throw a gernade underneath and see which goes the highest and then try to keep it in the air
