How to keep from spinning out in the rain?
So I understand that it is easier for the car to spin out while it's raining, but it just does it far more often than I think it should. If I end up in the dirt while it's raining, if I make any attempt to get out of the dirt at a more than 20 mph speed, my car will spin out almost every time, regardless of how straight I keep my wheel. I was wondering why technically that happens (either according to real physics, or just the game physics) and what I can do to stop my car from being outrageously uncontrollable in dirt while it's raining. That way I don't spend two minutes in a small dirt trap stuck doing 30 unintentional donuts. I am using Logitech G920 wheel and pedals FYI. Thanks!

Throttle Control. Pure and simple.

Torque per vehicle is distributed differently. It takes practice, and knowing when it down-shift, or to simply hold lower RPMs in a higher gear to counter the loss of traction.

Additionally, minor corrections to steering apply. Widen the turn radius, and contemplate the sharpness of your angle into, and out of corners. Depending on the apex itself, you can also "coast" through the corner with enough forward momentum from gathered speed before hitting the corner, and power out of the corner with controlled velocity when the wheels are more aligned (front and rear).

It's also important to take into account tire settings like preassure, and related braking & control systems that have an affect on how the tires control traction to the surface.

Finally, weight of the vehicle and dimensions in relationship to HP output/torque curve. This is probably the most overlooked area within Project Cars, because it is something of a "hidden" contribution. A perfect example of this very thing, would be the Ford Mk. IV. Arguably the most difficult car to master in wet weather. It has a Kar Kraft T44 transmission, high torque curve even at low RPMs, and unbelievable weight to horsepower output. As such, a "light foot" is needed more times than not, as the backend can break loose quite easily.

It takes a lot of practice, and even more control. Knowing when to "glide," and when to "push it to the floor" makes all the difference.

First thing is make sure that *both front and rear* are on rain tyres.

So the physics of spinning out even with straight steering is, when the rear wheels are spinning, they have much reduced lateral grip regardless of slip angle. However, the front wheels are not spinning, and therefore has lateral grip that increases with slip angle. This means, if your car gets even a tiny tiny bit of slide, the front is going to rotate the car to increase that slide. And the increased slide is going to increase the front lateral grip, which then further rotates the car and further increases slide. It keeps going. All of this happens even if you hold the steering wheel absolutely straight. This is real physics. It's called unstable equilibrium.
