I don't have a 951! So with limited power and grippy tires, Its rare that I can drive it with my right foot! Trust me, I've tried.
I need to tighten up my rear sway bar, but it seems like invariably I do that, and then I've got way too much over steer...
Doesn't help that in that video I had been on a nearly year long autocross hiatus, so most of the problems you see are the loose nut behind the wheel..
