3. It's outdated
Ford will replace the solid rear axle in the Mustang with a fully independent rear suspension (IRS) in 2015.
Long overdue, debates about what what’s best for drag racing are irrelevant. For the car, and for the vast majority of drivers, IRS is better.
Certainly it’s better for road racing, though the flaws of the current ‘Stang’s setup are never really as obvious on a smooth racetrack. Rather, an independent suspension will deliver a vastly superior ride quality, something all drivers will appreciate.
The 2015 Mustang’s new suspension will do away with excessive wheel hop and our tester’s horrendously choppy ride .
