Anyone who’s ever hit a slick patch on gone up over a curb knows that sometimes your car wheels spin at different speeds. (And we hope you and your car were okay.) But even when rounding a corner under more normal conditions, wheel spin can make a big difference in handling. Each of your car’s wheels travels a different distance when cornering, and thus need to spin at different rates as well. A good differential will reduce slipping or pushing and help you corner with confidence.
