No-Load/One-Wheel Syndrome
A common misconception is that a Torsen-Style Differential is useless under a no-load situation (e.g One wheel in the air). Although true to an extent, this no-load situation does not apply to the modern day car with Traction Control (or eDiff). For those without traction control, there is a very commonly used solution to the problem (used by professional race car drivers over the past 30+ years) that our competitors will not tell you; simply left-foot brake
