If you´re 3-4 seconds offpace in a car with fixed gears and only a few setup options, you´re having other problems then just the wrong setup.
But if someone has a setup which get´s you 4 seconds compared to stock, me and a lot of simracers would pay good money for that.
my suggestion is: Watch the faster guys replay, pedal imputs, line etc.
Don´t be afraid to ask them for help. Practise together on one of the Public Servers with the actual combo.
I bet most of the "faster" guys would love to help others improve.
