The idea is that the Quaife L*D is more progressive and less 'snatchy'/unpredictable compared with the original e-L*D, which is also prone to failure when being used on modified/aggressively used cars. And of course one of the main benefits of the Quaife as always is that it has no wearing internals, meaning no servicing or needed to rebuild or replace in the future - the ultimate 'fit and forget' L*D! The new BMW G29 Z4 40i & A90 Supra Quaife ATB Differential, now in stock.
