Considering that I'm already a previous vicitm to a broken Stock Diff, it takes alot to break the piece, Trust Me!! IMO the Open Diff provide better launching than the Quaife with street radials, at least from my experience, strange but true. Though the Quaife makes a world of difference on a road course and Solo2 from my extensive experience, if you don't plan to do such events much, than just don't be to harsh on the stock diff like I was because it's not cheap as D=man has said to purchase/install.
Have you ever seen a Tour go Toe to Toe w/a 300Z TT through the first 60ft.???
