This newest batch of bonus races seems to be easy to do with some stock/lightly modded cars, but for those who want to make them competitive, here's the times the fastest car seems to put down for each race. I also included the tires that the computer uses.
For example, in the Volvo race; the Focus RS is the fastest car you face. He should do a total time of 11:52 give or take some milliseconds. If you take your C30 into practice and tune/de-tune it to achieve laps of 2:24, you should finish the race in about 11:52. This way those who want to make these as competitive as possible can use practice to figure out how to do so.
