Its time for the next modification to my Mini R59 JCW Roadster. This time I am going to replace the differential. Questions is though...what is a limited slip diff, how do they work, how do they improve the car, which type should I buy and how are they made ? I was invited to Quaife, specialist diff and gearbox manufacturers, for the tour of they factory and to find answers to all of my questions. Thanks to Quaife and Lohen Mini for arranging the visit.
