On planet Rilgar go for the Hoverboard race. Not long after you start the race the track will bend right. You can then either hover on the left side of the track for the lower level (the same level as you are) or you can use a small ramp on the right hand side to jump up the upper level. Go on the left. As soon as the lower track gets wide again there are 4 boxes at the very right edge of the track. Drive through the boxes straight to the water. You are killed and the games starts putting Ratchet a bit in front and left of the boxes. BEFORE the game start press both keys "right" and "down" on the left side of your keypad and the Ratchet will hit the boxes again (and get 8 bolts for this). If you keep the buttons pressed all the time (use a strong rubber band or sticky tape - whatever works) you will get on average around 10,000 bolts per hour. This is no glitch in the game - it works every single time.
