The Mk8 irs is the same unit in the Mustang Cobra--and it is very stout. the TBird unit is almost identical, the exception that the Lincoln center section is aluminum. the Super Coupe uses the same unit as the Mk VIII, as does the Mustang Cobra. Plenty of gear choices as well. the only knock on the unit has been a weakness in the driveshafts themselves in hi output applications under extreme duty conditions. If you plan to push your car HARD, regularly, I would get a set of hd axles made up. Best place to find a set is in one of the hot Rod mags for import cars, if those guys can make a set of FWD axles that can run in the 9's, i'm sure they can make some stout ones for you!!
