This was on 17 HC (in my ownership, I bought them used!) Pirelli DH 305/315 Non-DOT Slicks. You can hear that the ZLE picks up inside rears on some corners, which requires you to feather the throttle when fully loaded up... not ideal. Car is 100% stock aside from the tires and Hawk DTC 70 pads front and rear. Also, larger OD rear tire means the speedometer registers 3.5% or so slow. Actual VMax on this lap was 142.8mph per Aim data, car registers 136.7 mph on Cosworth Tool.
