The 2015 is comfortable and nimble on the street. It has good power and a great sound too. We were anxious to get on track, do a real burnout, and launch on a prepped surface. What we found is that the 2015 Mustang is tricky to launch compared to the out-going S197 Mustang. Why? In layman’s terms, the live axle in the S197, which is considered somewhat crude, provides great feedback for drag racing. The three-link suspension does a fantastic job of planting the tires and transferring the torque loads to the body to create pitch rotation (nose lift) to transfer weight from front to back. The heavy axle assembly also gives lots of feedback to the driver and really communicates what the tires are doing.
The suspension is a little on the stiff side but that’s to be expected in a car that is setup for the track. Trust us, you wouldn’t want a floaty suspension with 650hp on tap. Speaking of suspension, Shelby has really done their homework with the Shelby GT as we were able to carve around more than a few corners at speed while the car gripped the tarmac and took it like a champ.
The Mustang was a blast at the track. Even famous author Stephen King, who happened to be at the track, came over for a look. He didn’t think it was too scary, so we doubt it will appear in his next book, but you never know. He has written about a car or two in the past.
While the drag racing launch can be violent (we’ve all seen racers dump the clutch and blast off the line), street tires require a smooth, controlled application of power to stay hooked. Your best times will come from getting off the line clean. Finesse is key. Believe it or not, we recommend novice drivers launch as if they were driving away from a traffic light, but with more rpm and slightly quicker clutch release. We would say 2,500 is a great place to start. Using this rpm, you’ll probably bog the engine a bit. No problem—add rpm, or get the clutch out quicker.
