of what the settings in NR2003 do. I mean the tool tip is cool and all but it doesn't really give you an idea of what interacts with what. I race but I am not a gear head, I just drive the thing. I know what I want to get out of the car but the minor adjustments I make don't do much, and then if I take on another part it seems to tighten the car too much. Any assistance would be helpful.
