It is that fast. It's the driver that's slow haha.
So if you're hitting the track then yes, some camber arms are a good idea but unless you have an idea of what to set them at I suggest getting a wheel alignment when they're installed.
The rear only needs around 1 degree or so the standard gear should be fine to start off with.
I run Hardrace in my car from JustJap but it really depends on your budget.
