The 2015+ S550 Mustang independent rear suspension quarter-mile world record has just been reset by Mo Makki and his turbocharged 2015 Mustang GT.
Weighing in at over 3,900 pounds sans driver, Mo ran his fully loaded street car and set a new world record not once, but twice yesterday with an 8.41 @ 161MPH quarter-mile pass running 23 psi boost.
This beast of an S550 features a JPC Racing turbo kit using a Precision 8685 single turbocharger, GForce Engineering bolt-in 9-inch fabricated independent rear suspension kit, Viking shocks, the entire BMR Suspension catalog of parts, TH400 transmission, and 17-inch drag radials.
