Yowza I've never had film of myself so maybe my hands dance around more than I realize. Are all GT2s like this? Ahh, the joys of owning a 50/50 weight distribution and underpowered sports car, otherwise I fear I would have to give up text messaging while HPDEing.
Two things make the hands much more busy.... Street tires , battling handling issues. That was the first time in the car. On top of learning the car I had to learn what was wrong with it as we had just essentially built it. While figuring out the T3 S2000 my hands looked much the same. As we got the car sorted out the hands calmed down a bit.
