Focussing too much on car settings or modifications is not good as well.
Standard or modify, lets be confident with our driving. Not learning at all is definite loss. 😄
If we test a setup and do 10 laps, 8 laps were consistent but another 2 were not good, it is normally "Driver issue".
If we tested 8 laps and fail, only 2 passed, then it is the "Car issue".
Modifications/systems/cutting/adding/redesign/others only needed when the "basic" was done. Only do these when the car is good. We want to change from "good" to "great"
Experience came from mistakes!
Have a good setup and compete on events 👍
