A factory limited-slip differential (option 471) is a prized and often-hard-to-find feature that many buyers consider necessary given the power, and it is frequently confused or misreported on listings. Owners note aftermarket Wavetrac or Quaife units are an easy retrofit and, in some views, superior to the factory unit.
