    want to improve my racing and basics understanding, so i watching youtube videos and trying push and roll and lift and etc. in Limerock with Skipbarber and USF2000
    so far my best with Skip is 1_01.4 (i dont have info about how low is rF2 times here) but 120% AI goes in 57xx and iracing times also is around 57xxx
    with usf2000 my average is 50.1 (59.9PB) BUT here i know people go 57.xxx
    can someone explain what to look in Limerock setup? is it fast or slow track?
    what and why to tweak in setup?
    atm i am tweaking setups quite blind, only chambers, wings, rolls, brakebias and trying to understand actions. also installed motec but dont have any clue what to watch and what to read...
    (i am watching "Skip Barber going faster" and iracing vids and tutorials)

    Controlling your left front tire on the last turn seems to be something to look at. Even though the main straight is fairly short, if you get the work done turning and setting the car, you can rocket down the straight. Remember controlling one corner of a car is also achieved by reversing the other corner. for example. Soft left front / Stiff right rear.
    However, if you are fixated on chasing the Aliens, prepare to be frustrated...

    With skippy and Limerock: for starter check which version of the car you use : the slick tires perform better than the threaded ones.
    You can get pretty fast even with mostly default setup, one of the most important aspect is brake bias and brake strenght.
    If I want to make the car a bit less tail happy, I just lower the rear ride height a bit.
    With such underpowered cars, on a small circuit like that, practice makes perfect : the most time gain is being able to accelerate more and sooner, then carry more speed through the turn, then braking later, last but not least the best trajectory to save some more time.
    The first turn is tricky because you have to decide which technique employ to gain the most, but then you have to flow in the following 2 turns, and the right path is very important, path that you cannot follow if you are too fast/wide through turn 2. It's a long time since I spent my time on Limerock, the less you push the faster you go, don't bother with setups, just drive.

    In my experience of usf2000 the wings have little effect on top speed compared to other cars, so i always stick the front wing on max and crank the rear wing up as well. Maybe around 18. Calming the rear for me helps get better traction out of the corners which seems to really help times in this car.

    ps i dont know anything about car setups :p

    In tuning options when you choose the car, you have both

    USF is very tricky with aero balance, 1 click can make a big difference in oversteer/understeer department
