I think a big part is the familiarity I have with the car. I know what its gonna do, almost before the car does. I have a lot of seat time and it is reflected in my results. There are a couple of cars I have like that, and many others that I still have a learning curve when I drive them. Hell, half the time if I run a variety of classes and then hop in this I spend a lap getting re-aquianted. Luckily so is everyone else so it evens out.
I'll have to look back over the toon and be sure I haven't tweeked anything since I posted this. I don't think I have but I may have installed a different gearset.
And Spiny, I'm sure that your setups would be too soft for me as I shy away from the rumble strips to take advantage of the stiffer setup.
