Famed Mustang tuner Roush has finally gotten its hands on the latest pony car, the redesigned 2015 Ford Mustang, and gave us a glimpse at this modified 'Stang last week in Detroit. The Roush-modified 2015 Ford Mustang will officially debut later this year, but we have early specs on the various states of tune that will be offered, including Stage 1 and Stage 2 performance kits.

Styling has always been a big part of the Roush upgrade strategy, and this new version is no exception. All Roush versions of the 2015 Ford Mustang come with an in-house body kit that take the car's looks in a much more aggressive direction. Gone are the rounded curves of the stock Mustang's front end, as Roush has replaced the entire grille and front fascia with its own sculpted bits that actually extend the nose a few inches further forward than in the stock car. There are also new hood vents and an optional hood scoop, in addition to rear fender vents and a redesigned rear fascia and rear spoiler that make for a significantly cleaner appearance out back.

These looks aren't just for show, as Roush claims that certain pieces like the front splitter, rear diffuser, and various vents up front actually improve the car's aerodynamic performance. The custom Roush 20-inch cast wheels are also slightly lighter than stock, and are wrapped in Cooper RS3 tires for extra grip. Roush models equipped with the Mustang's factory performance package also include upgraded brake pads and rotors for the Brembo six-piston calipers, and Roush will also offer two types of adjustable coil-over shocks.

Like it has with previous Mustangs, Roush will offer various levels of tuning kits, including RS, RS1, and RS2 for the new car. But given the 2015 Ford Mustang's expanded engine lineup, the structure is a bit different. RS kits are for Mustang V-6 models; RS1 kits focus on the turbocharged Mustang EcoBoost; RS2 uses the naturally aspirated 5.0-liter V-8; and we can assume that, like with previous Roush Mustangs, RS3 adds a supercharger to the V-8 with various stages of power available.

We saw an RS2 car up close and were impressed with how Roush's appearance kit looks in the flesh. Although we can't speak to how it drives yet, hearing the raucous sound of the Roush's new active exhaust system on this RS2 V-8 car certainly grabbed our attention.

Expect to hear more details on these various levels of tune later on, as well as pricing for these various upgrades. Roush will also offer nearly all of its parts as stand-alone options for Mustang owners who want to focus on certain elements of their cars like wheels, brakes, or appearance. Stay tuned for more information about the Roush 2015 Ford Mustang as the tuner readies its special Mustang for its debut later this year..
