The reintroduction of the Boss 302 in 2012 came close, but only in 2015 did Ford finally ditch the solid rear axle for modern technology and an independent rear suspension.
Despite its new rear end, the Mustang hasn’t been able to shake off all its past. It’s larger than ever, and when the road buckles, the Mustang bobs and weaves more than a sports car should.
In theory, Performance Package 1 should fix the Mustang’s dynamic issues, but it doesn’t. The new Performance Package Level 2 does.
Finally, the good stuff
Pony up $6,500 for the Performance Package Level 2 and the Mustang gets what it needs: magnetically controlled shocks (a $1,695 option on top of Performance Package Level 1), a 67-percent stiffer rear stabilizer bar (24 mm, solid), a 12-percent stiffer front stabilizer bar (33.3 mm, tubular), 20-percent stiffer front springs, and 13-percent stiffer rear springs.
For good measure, Ford wraps 19 x 10.5-inch front and 19 x 11-inch rear aluminum wheels in large 305/30 Michelin Pilot Sport Cup 2 superhero tires that are so wide, they stick out from the fenders (which are 1.5 inches wider than Performance Package Level 1 tires and the same as the Shelby GT350R’s front tires).
The same Torsen limited-slip differential with a 3.73 axle ratio as Performance Package Level 1 handles the rear end, but the electric power steering system’s been recalibrated for quicker response.
A new front splitter–inspired by the 2012 Boss 302 Laguna Seca’s splitter–that sticks out 3 inches around the front corners creates about 24 pounds of downforce at 80 mph, while 6-piston Brembo brake calipers clamp down on massive 15-inch rotors up front to haul things back to reality.
Finally, less bob and weave
How does it all work? Does it cure what’s left of the Mustang’s handling shortcomings?
I blasted around the track at Monticello Motor Club on Wednesday, in a Kona Blue Mustang GT equipped with the Performance Package Level 2, as heavy storm clouds rolled into the area. It’s clear Ford’s finally done what it should have in 2015.
Bomb into a corner hot, brake hard in a straight line, clutch in and downshift from 4th to 2nd, turn the steering wheel, look to the apex, and roll quickly into the throttle. This Mustang responds with flat precision. With the new package, the Mustang finally has the suspension setup it’s needed since the 6th generation launched three years ago.
Though there’s no Shelby badge, this Mustang has shockingly little body roll. It manages weight transfer in corners more smoothly, and the stiffer springs and stabilizer bars mean the Performance Package 2 Mustang doesn’t bob and weave on cracked roads like a prizefighter, though the wide, sticky 305s want to explore ever crack and crevice they roll over on public roads.
The magnetically controlled shocks—something the Mustang GT’s desperately needed—help the stiffer suspension setup keep everything firm and controlled without being harsh or jarring.
