Don't waste time on those BS front wing setting ... etc ... the effect is very minor if u don't have the right tires ... this is also my own experience.
"Getting this car to work is 95% tires... and what seems to be the best approach is to go as soft as you can for the rear and then play with the front compound to balance the car... spending time with setup when you don't have the right
tire is a waist of time and will drive you crazy...
I finally have my 104 just as easy to drive and as fast as my 103..."
