On the dragstrip, our car regularly runs 11.20s at 123 mph, and 60-foot times average in the 1.55 to 1.57 range. We didn't better our best time of 11.23 or our quickest 60-foot clocking of 1.54. Like all dragstrip testing, track conditions and weather has to be factored in to results, and we feel that is what affected the results this time around.

The car's best times have always come later in the season, when the air is optimal. We tested these modifications at Atco Raceway in early September. The oppressive summer heat was gone, but the temperatures were still in the mid-80s. Last year we ran our best times with this car when the temps were in the low 70s. That said, this Mustang is deadly consistent as it ran—with the Steeda modifications—11.27 at 122 mph with a 1.56 60-foot time in the hotter weather conditions.

On track the car was flying, and we were enjoying the lowered look but there was something missing—new wheels! We added Shelby GT500 wheels four years ago, when we changed to the Ford Racing GT500 Brembo brake package, and it was time for a fresh appearance.

There actually wasn't too much thinking in the matter as the author instantly gravitated towards AmericanMuscle.com AMR wheels. The charcoal AMRs seem to be a crowd favorite for the '11-present Mustang, but we haven't seen any on earlier S197 models ('05-'09).

AmericanMuscle's online ordering is easy and we clicked away at the order form. The company shipped staggered fitment AMR 19-inch wheels wrapped in General G-Max tires. Up front, the tires are 245/45R19 and are mounted on 19x8.5 inch AMR wheels. In the rear, the G-Max tires are 275/40R19 and the wheels are 19x9.5 inches.

AmericanMuscle makes it super easy to swap tires with complementary mounting and balancing, tire pressure sensors, and a DVD on how to calibrate the new sensors to your car's PCM. We didn't change the overall height of the tire size, so we didn't need to recalibrate the speedometer.

After one day's worth of work, a trip to the track, hundreds of street miles logged, and hours of staring at the car, we are confident in saying our '07 Mustang GT sits just right, drives smoothly, and continues to mow down the competition.
