Have you been to the track?
It sounds like you need to NOT dump money in this car and take it to the track as it sits.
From the questions you're asking, it also sounds like you need to focus on YOUR driving abilities, not the cars.
Don't boost this car, as it makes it unreliable.
Don't dump money into it, because you'll learn the car's limits sooner\better, once you know them, upgrade stuff as you go along.
