For most enjoyment and improvement overall, in all aspects, learn how to make your own setups.
You can still use default setups or other people's setups, but have to dial them in.
If you assume a setup engineer was competent, there are only three setup variables to start tweaking.
1. Steering ratio
, so when you move the steering wheel the car does more like what you think you want.
a. Guaranteed, it is only by coincidence someone else has dialed in their rig the same as yours
b. Guessing with a keyboard a driver would want a much higher ratio than a wheel user
2. Anti-roll bars
, (ARBs), moved in opposite direction to each other to achieve neutral steering balance.
a. understeer - reduce front ARB and increase rear same amount
aa. the front ARB is too stiff and not allowing the car to roll which increases grip on outside
b. oversteer - increase front and reduce rear
aa. the front ARB is too weak and is allowing too much roll making the car seem to turn in too quick
c. only when a or b does not seem to help things do you move on to other setup variables or move one ARB more than the other
3. Brake bias
a. generally, you want to get it to where, if you slam on the brakes and lock them up, all four tires begin to show skid marks at the same time, with the front starting just an instant before the rear.
b. But a is a matter of opinion, other driver's seem to want the rear brakes to begin leaving skid marks just before the fronts.
c. My opinion is don't use them 98.8 percent of the time
Don't mess with springs, shocks, toe...anything else.
You are assuming all that is good.
All you want to do is the minimum to match their setup to you and your rig.
