The M2 can fit a set of 4 tires in the back seat, so I drive to the track on PS4S on OEM rims, and carry my track tires. If it rains, I leave the PS4S on.
And if I cord out a track tire, I can still get home
I just watched some video from a GT3 that was behind me this past weekend at COTA... Between the track temps and my driving, I'm not surprised I killed the tires. But which came first, the sliding or the tires dying? Who can say.
