Few more questions. How much does the stock undertray affect aerodynamics (1sec - 1min track?..etc) and cooling for brakes (change in temps?...etc). Back in March my undertray got destroyed when i went off T8 sideways to the inside. Nothing else broken thankfully. Havent got a chance to replace with beatrush or something.

 

So last time you had your OEM undertray on, but since it got destroyed, this time around you were running without the OEM undertray? If thats the case, im sure the lack of your OEM undertray was slowing you down. I honestly cant estimate by how much though. By not having your OEM undertray you were probably generating some lift on your front end. Beyond that, it sounds like this time around it was hotter. There are too many different variables to consider. And youre learning that dropping time from here on out by just relying on your progress is going to get harder and harder. Because not only do you need to improve and execute everything consistently, the weather has to also be favorable. The track on any given day can be an x amount slower.

Overall i think youre doing well. I didnt have much time to look at it in great detail, but i noticed 2 general things. One, your braking input is still occasionally off. In a few places you got on your brakes a little early. You realized you got on them a tad early, so you lifted. Then you got back on them again. That entails time lost. You want your brake/throttle input to be seamless in transition. Beyond that, you were using different gears in a few places this time around. Instead of shifting into 5th you were stretching out 4th gear. Hard to tell if that was rewarding or not. Youre going to need data acquisition to figure out those details. I dont have one so i cant recommend one specifically. Ive used my friends unit on a few occasions and i know that without it everything is a guessing game as opposed to somewhat factual data.
