Setting your opponents (AI) series strength.

The actual opponent strength can be fine-tuned using the AI settings given in the Series file.
 You can set your opponent strength while "trying" out the series.
Go into the series and practice against the AI at the race you are setting up for. 
Determine whether the AI cars should be faster or slower, exit the sim without saving the race and edit the series.str file in Notepad.
You will find the series.str file here..
C:\Games\Infogrames\Dirt Track Racing2\data\series\_____________series\series.str
Scroll through the events and before you get to the 'drivers', you will see the following settings:

[drivers]


; To adjust your AI strength, use the chart below and replace

; the following values with the ones in this chart
;
; Strength 1 best ability=1.00 worst ability=0.85 (slowest)
; Strength 2 best ability=1.05 worst ability=0.90
; Strength 3 best ability=1.10 worst ability=0.95
; Strength 4 best ability=1.15 worst ability=1.00
; Strength 5 best ability=1.20 worst ability=1.05
; Strength 6 best ability=1.30 worst ability=1.15
; Strength 7 best ability=1.50 worst ability=1.40
; Strength 8 best ability=1.70 worst ability=1.60 (default)
; Strength 9 best ability=1.80 worst ability=1.70
; Strength 10 best ability=1.90 worst ability=1.80 (fastest)

best ability = 1.70
worst ability = 1.60
spread modifier = 0.90

Values given in the chart above, change the settings. If the AI are too slow and those are your settings, 
you would use Strength 5, and 'adjust' best ability to 1.20 and worst ability to 1.05 and click save.
