Rollover stability is all about 3 things: CG height, track width, and tire grip.
To prevent rollovers you can reduce the vehicle's height by adding lowering springs, and increase track width with lower offset wheels. Tire grip is important because if grip is low enough, you will slide before you roll, but if you put really sticky tires on it will be more likely to roll before sliding
