Front-wheel-drive cars dominate the market, but they naturally understeer because the front tires must handle both propulsion and cornering forces.
To improve FWD handling, the key is shifting more cornering work to the rear tires. This can be done by increasing rear roll stiffness with stiffer rear springs or a thicker sway bar, which loads the outer rear tire more. Stability control allows even higher rear stiffness because it can intervene if oversteer becomes excessive. Rear alignment also matters: most FWD cars use rear toe-in, which increases understeer, but switching to zero toe or slight toe-out reduces it.
Better traction also comes from higher rear roll stiffness, which helps keep load more evenly distributed across the front tires and reduces inner-wheel spin; if that still occurs, a limited-slip differential can help. Improving front grip through negative camber, more caster, higher tire pressures, or stickier front tires also reduces understeer. Driving style plays a role too: adding throttle in a FWD increases understeer, while lifting off increases rotation. In a tightening corner, this natural lift-off rotation makes a well-set-up FWD more intuitive and forgiving compared to a RWD, which may require power-induced oversteer to rotate the car.
