on my daily street tires which are nitto 555r's. These tires are definitely holding me back. With each run I made they began to slip more and more. I was also getting a lot of wheel hop so I will be re-installing my other subframe with ES bushings and buying a set of et streets. Best run was a 11.6 at 123mph with a 1.75 60ft but it's got a lot more in it still.
