Only the terminater cobras had the irs... 03-04. That's it.. The problem with the jag stuff with air ride is it dosent have upper and lower control arms... So it just dosent travel well... But the tbird or mark 8 are imo the easiest to fab up cuz it has axtual upper and lower control arms and u wont fight the toe problems through travel that most get... And parts are plentiful and not expensive..

All 99-04 Cobra Mustangs had IRS, not just the 03-04.

Tired of being beat in the power game by the V8 Camaro and Firebird twins, Ford has beefed up the SVT Cobra considerably for this year. Not only does this pony feature more horsepower (320 at 6,000 rpm) than before, but it comes standard with independent rear suspension, a first in the Mustang's 35-year history.
