Port my own heads?

Yeah it felt like the car was swaying back and forth a lot! I kept feeling like I was gonna lose it and smash the wall. The slicks we're m/t ET drags, that were 14" 28 x 9's I was running 15 lbs in them if I remember right. They were really whipped though I borrowed them from a friend just to see how it would do. I dont know if being trashed had anything to do with the loose feeling the track I test and tune at isnt the greatest either, But its the closest to home.
