Lighter pedal effort (40lb. pedal effort on the stock 03 Cobra), which wouldn't apply here. It also had smoother engagement, less chatter, cleaner disengagement allowing better WOT shifts, and better power handling. It didn't slip at all when changing gears, all the power went to the ground when you let the clutch out under hard acceleration.
If you're planning to keep the car stock, power handling and everything may be fine on the stock clutch, but I have noticed that it is less than smooth in stop and go traffic. I won't keep my car stock, and the OEM clutch will start to show it's limits sooner or later. As I said, JMO.
