Porshe Club of America had a rally at Road America (?) in Wisconsin, I was in high school in charge of checking wheel lug torque at the safety inspection. Some guy took me out in a slope nose 930 Turbo around the track a few time and I thought I was goona die, said we hit 160 a few times.
With a 14month old so there is no chance of anything close to that happening again, maybe 100 in the MM
