Havent yet driven on the new setup but have driven plenty with the Quaife LSD. Installed the quaife about 3 years ago after I siezed the stock LSD at the dragstrip. Have done plenty of track days (circuit as well as drags) and am very happy with how it performs. There was some issues with mine when they tried to fit it as it had not been machined correctly (and horsepoer freaks later sent an email for a recall) but my diff shop managed to set it all up correctly after they machined it.
