The 2015 Mustang is no secret to us enthusiasts! However, one particular change that has drawn most of the attention is the return of the independent rear suspension. If you know Mustangs, then you are well aware that the only IRS (independent rear suspension) offered from the factory was found on 99-04 Mustang Cobras. I'll be honest, Ford really did have their cards played well with the aging solid or live axle setup. At the same time, it really was time for a refresh to stay competitive within the sports car market.
The IRS underneath the redesigned 2015 Mustang will still feature a 8.8" center section, however Ford still threw a twist at us. The ring and pinion gear are both different from the outgoing solid axle and will require a specific gear kit for the S550 IRS. Furthermore, I'm sure aftermarket manufactures and Ford Racing will be on-board offering state-of-the-art suspension upgrades to keep your Mustang ahead of the competition. Nothing is available as of yet, other than Ford's upgraded half shafts.
Regardless of what your opinion is, I would strongly recommend you go out and test drive a new 2015 Mustang. I'm sure it will change your attitude toward the drastically altered American pony car.
