These include: unique stability and electronic power-assisted steering, six-piston Brembo front brake calipers with large diameter rotors, bigger radiator, silver-painted strut tower brace and a Torsen rear differerntial with 3.73 axle ratio.
Just because Ford's 5.0-liter Ti-VCT Coyote V8 has been updated for 2018 with dual-injection and fancy new cylinder liners doesn't mean the Mustang's other engine option - the 2.3L EcoBoost I4 - deserves to be overlooked.
The package will add $6,500 to the cost of a Mustang GT fastback manual, the only model for which the package is available.
The most immediately obvious changes can be found on the exterior.
In addition, custom tuned MagneRide dampers will give the Mustang sharper and a more precise handling. There's a custom high-performance front splitter and rear spoiler, created to add more downforce into the corners, with black detailing, and exclusive ten-spoke alloys. To keep all the mass in check through quicker direction changes, spring rates are up by 20 and 13 per cent (front and rear respectively), while anti-roll bar stiffness has been increased too, 12 per cent at the nose and at 67 per cent at the back. Called the Performance Pack Level 2, it has all of the added benefits of Performance Pack Level 1 but has some unique extras to boot.
The chassis has been upgraded with double-adjustable Eibach Pro-R2 coilovers, and three-way-adjustable Eibach sway bars - 36 mm front, and 25 mm rear. Combined with the retuned suspension, the wheels bring the Mustang more than a half-inch closer to the pavement.
The latest performance pack is the result of afterhours work by a crack team of engineers at Ford in the US.
Jamie Cullen, Ford supervisor for vehicle dynamics development, was in charge of the road tests to ensure the auto delivers ultra-responsive steering, braking and handling performance. "The auto has lightning-quick response and never gives up grip". In the United States the Level 1 package costs $3995, but be prepared for that to rise a lot.
The goal of the model isn't to create the ultimate track auto, like the 1LE packages on the Chevrolet Camaro SS and ZL1, but instead to make a daily drivable weekend canyon carver that delivers on the promises made by the Mustang's formidable powertrain and stiffer chassis.
