Hi guys, just my 2 cents worth (which is about what its worth!!!), rear toe, firstly, IMO, there is no "correct" setting.
It depends upon rear suspension design AND (more importantly) what driving characteristics you want from your buggy.
Remember, the following opinion is dependant upon the type of suspension, tyres, terrain, driving style and a million and six other variables.....
Some toe in tends to make the car track with the front of the car more, and this can induce some "push" or understeer. Some might call this "stability or stable"
Some toe out allows the car to change direction easier and can become "skaty" in the rear at. This can induce oversteer or as one guy I used to race against said, "it makes his bum happy", I never really went any further into that description!!!
.
Soem might call this "unstable" not me though as I prefer a car that slides a bit My racing is on hard packed ground for the most part and I want to throw it around and slide some, steering with th rthorttle to a degree.
IMO, this builder should aim for Zero toe and leave some adjustment at either side of this so he can fine tune the machine to suit his own driving style as he become familiar with the buggys handling characteristics.
