Here's a little different flavor- here is a video of my brother driving the GT4 coming on track right behind me in the 1LE at Mid Ohio last weekend in the instructor run group. My car was on Yokohama non-dot take-off slicks, the GT4 is on Pirelli Pzero non-dot take-off slicks. Once my brother warmed up the tires, we had a blast snaking through traffic together... I just wish we would have gotten a few more laps! Only one close call, when he carried a little too much speed on entry to T7 and dropped two wheels in the grass. Amazing how well matched the 1LE and GT4 are on track.
