Can you practice, run a qualifier or race without crashing even once?
What is the difference between your fastest lap and your overall average lap?

If the answers to these questions are not "YES" and "1/2 sec or less" you probably wont be able to notice a .5mm change in any setting on your car.

Andrew and Corey can drive and tune precisely because Andrews fast lap is a 9.2 and his slowest lap is a 9.5 over 5 minutes.

I am not saying this to make anyone feel bad. Its just important that up and coming drivers focus on clean driving and when they get consistent then its time to start sweating the fine details.
