Default Full-scale camber vs. camber as practiced in 1/8

I've noticed that in full-sized racing cars such as F1, Touring, and Rally, the front wheels have significantly more negative camber than the real ones, whereas in 1:8 off-road, all set-up sheets I've seen have more negative in the rear.

What is the principle behind this?

Caster settings in RC are different. In real cars the faster you go, the lighter the steering can get, in RC it's often the opposite, servos work hard at high speeds. Caster affects your camber settings when you turn the wheel.

They have less caster, so they have less increase in camber when turning. So they need more camber to make up the difference.

Rear camber is mostly based on chassis roll in turns. You want to keep the tires flat on the ground. RC's often have more roll than real race cars, like WRC. Sometimes I increase rear camber to loosen the rear end and prevent traction rolls.

Also some race cars, like 1/10th 2wd roll onto the outside sidewalls in fast turns and pick up grip like that. It's complete nonsense, but it works.

F1, despite the fact that they are on road, have very familiar settings. -4/-3 and 2 toe out is common. And stiff bar, soft spring, setups like us.

Running the front tires on just an edge instead of the complete surface is giving less resistance when running in a straight line. Beside that, racing cars go a lot faster through the corners, a piece of roll with the re-shape of the tire through those forces the tire gives the right grip in the corners.

Not to mention none of the full size cars have nearly the suspension travel. What works for toy cars and real cars are different things. Nothing scales up or down. If it works for an 1/8 scale buggy and not on a rally car, who cares?
