if your trying not to run a 13@150 MPH you will launch your car hard.. I dont think Joey and al powers are making these cars to "drive around in traffic leisurely". They are made to put up solid numbers at the track which requires getting power down to the ground for the best 60' possible.. The byproduct of this on a front drive tranny that is squatted and sagged during a launch with all the weight on it and LSD and drag radials and massive power = broken drive train parts..
