What i have found to work as a fast baseline for gt cars (and cars with less downforce) in rFactor 2 driven on most circuits:
Less camber, cooling, wing angle = more top speed
Ultimately it is up to you how to combat the front heavy aero balance. The fastest solution rarely is to simply increase rear wing angle.
From here on you start to add stiffness, rear wing and so on if needed for the track.Limiting the suspension movement with stiffer springs and anti-roll bar will also result in less camber gain during cornering. This means that you will have to increase the camber angles, leading to unwanted heating of the tires.
Some setup values were not covered by this overview as they are less significant for the car's performance. However, differential, toe angle and damper settings can be huge for dialing in the car's balance to make it drivable for the driver.
- Springs: lowest possible
Only increase if the floor seems to be generating too much unwanted aero balance change in braking
This has become noticeable in recent updates to official GT3 and GTE cars. It can be possible to balance this out with packers as well. - Dampers: lowest possible
Only increase if the car becomes wobbly on bumps and kerbs - Camber: lowest possible
The aim seems to be heating the outer part of the tire during cornering and having the tire quite close to flat on the straights. This is of course dependent on how much cornering vs. driving straight there is during a lap. MoTec comes in very handy in this.
Lowest camber angle will allow the tire to cool down in the straights and allow for more top speed due to less heating generated by tire deformation. This will help keep your tires alive and within the operating range of temperatures. Less overall heating in the tire over a lap will also lead to less tire pressure rise in air filled tires. - Tire pressures: lowest possible
Lower tire pressure will allow for larger contact patch.
There is little to no benefit using anything higher in rFactor 2. - Aero: lowest possible
Only increase rear wing angles if there is a lot of medium to high speed corners where there is no weight on the rear.
This will result in very front heavy aero balance, which you will have to balance out with spring rates so that your car will not have rake gain with increased speeds/aero forces. MoTec comes in very handy with monitoring the rake, although it is very noticeable as well during driving. - Ride heights: lowest possible
GT cars typically have high minimum allowed setting meaning that you will almost never bottom out.
Lower ride height will allow for more top speed and lower center of gravity.
Many cars will work best having the rear ride height set slightly higher than the front but by lowering the rear you can fix some of the problems caused by front heavy aero balance. - Anti-Roll bar: lowest possible
ARB is mostly used for changing the car's overall balance. In most cases the optimal setting is having some ARB on the front, none on the rear.
