Enter a "Hot Lap" trial in any chapter, a trial in which you only need to beat a lap time, not one of the average times. Start the race, then on the first lap, get the time needed. You now have passed the stage, but do not end the second lap. Find a good, straight portion of road. You get Kudos for turning with the handbrake. Go to one side of the road as fast as you can. As you are approaching, do a 180 turn using the handbrake. If done correctly, the words "Wey Hey" should appear on the screen. Next, drive the way you are facing to the other side and do the same. When moving the wrong way, you need to spin 180 in order to get the Kudos. Just keep repeating this, then finish the race. For every five minutes that you do this, you will get approximately 1000 Kudos. There is no time limit. The best city for doing this trick is San Francisco, as it has wide roads. Play jokers to get more points -- if you do this for 20 minutes with a joker, you can get more than 8000 Kudos in just one race.
