I run it on ToyoR888's so 60ft are only in the mid 1.8's somehow I did manage a 1.76 60ft on them once. On Michelin Pilots it goes 11.90's with 2.0 to 2.1 60's. Also, I have drag raced stick shift cars my entire life so, once I leave the line its flat to the floor ,flat shifting till the end which helps a ton.Your trap speed is pretty damn good. Picked up 6mph over stock. How have you not twisted an axle yet?
