•   Ford 8.8" Rear End (2007-2010 Ford Explorer) including inner stub axles/CV joints
•   A Driveshaft (install instructions include a variety of recommendations)
•   Rx-8 rear diff isolators (user's choice of style but we like polyurethane). 

The Ford 8.8 is a substantially stronger diff than the factory Mazda rear end.  It's available in a huge range of gear ratios (3.08:1 up to 5.71:1) just looking at Summit Racing.  We use a donor rear end from a 2007-2010 Ford Explorer.  It's an aluminum case with dual front mounts and each front mount is massive.  The support on the Explorer makes the Cobra 8.8 front mounts look tiny by comparison.  Furthermore, the Explorer parts are both easier and cheaper to come by than the comparable Cobra pieces.  Everything mounts from the topside which dramatically improves the load path AND you'll retain close to factory like exhaust clearances.  Note: 2006 is a conversion year but so long as it has the dual front mounts that's what you want. 

How much power will it hold?  Well, wheel hop can still kill most things but from the few folks who've managed to break things on our Rx7 kits we can say somewhere around 600-800 hp is a reasonable approximation.  We've had folks who've made 1000 hp successfully while road racing.  The shafts come with a lifetime warranty so if you do break one just let us know and we'll send you another (international users we ask to pick up shipping).
