Good launch traction, handling is very stable up to 150 MPH (that's as high as I've tried). They look awesome on the Cobra.
Ride is rough but it is a Z-rated UHP tire, so that is typical.
My only complaint is that it follows truck grooves in the highway pavement pretty badly. You can feel them pull sideways while driving on a well traveled road.
Overall, they were a spectacular bang for the buck.
