Yes. For the front, go to the steering slot in suspension_F.jbeam, and change the precompression on the tie rods (beams will be something like [fh3r,fh6r] and same for L side). For the rear, it depends on the vehicle. You will have to look in suspension_R.jbeam, and in the list of beams you may already find a set of beams that have precompression set for toe. You can change these values. If not, you will have to pick some hub or suspension link beams that you think will work and add precompression. Make sure to set the precompression back to 1 following your chosen set of beams.
Toe can help with the stability and handling of cars, all cars run different amounts of toe best suited to them, as a general rule FWD have toe out, AWD neutral and RWD toe in, there are some exceptions to this depending on the use of the car.
Some very powerful RWD cars have a touch of toe in on the rear wheels to improve control when the wheels are lit up, but otherwise nay, most cars have basically no toe to preserve tyres. Don't know where you heard about toe in or out for different drivetrains, but that's not really correct, afraid to say. Would like to add that lots of toe out on the front wheels makes nearly any drift car easy to catch... In BeamNG at least...
i was mostly talking about front tires, for example because fwds have the driving wheels are pulling the car the rubber suspension/steering bushes squash in and cause the front wheels to have slight toe in while driving, a correct wheel alignment will have just enough toe out so while driving the wheels will have neutral toe. Had to learn all this while doing my automotive apprenticeship a few years ago, so it might be less true for newer cars, but i know from experience that correct toe is needed to take up the slack in suspension and steering components.
D'oh! You're right. I had my car's multilink in mind where some of the joints are located near the centreline of the wheel, so taking the slack under accel alters castor more than toe, haha.
Camber is similarly adjustable by adding precompression to certain beams in the hub, or to an upper suspension link. It gets more tricky with multililnk suspensions, where camber and toe intertwined making it difficult to set them independently.
Seen this from a previous thread called "Camber" in suggestions, where DrowsySam ended the topic by showing a pigeon with loads of camber and explained a similar method of modifying it. However toe obviously uses steering for the front wheels.
