Combined with the tires.. I would say weight is key.. but it is a combination of center of gravity, weight distribution and weight transfer.. that’s why people buy lightweight bodies.. and then add weights on the chassis to make sure they hit minimum weight.. springs and dampers help you dial in how the weight moves around when cornering.. goal being to have it push down on the tires that are about to loose traction… but not too much.. cuz then it will traction roll..
