That looks like a BLAST! Well done. What was it like driving the ring with the other cars and bikes running the track at the same time?
To be honest, on the day I had the HellCat on the Nordschleife there wasn't much traffic so it was fun. Most people are pretty good at getting over to the right when being over taken. I only drove about 80% that day because I still had the stock all season tires on and as you know, they will not put the power down. On the GP track however, they were manageable and even kinda fun hanging the rear end out coming off the corners.... It was slow as hell but the other drivers seemed to get a kick out of it. I ended up playing with a Miata, I'll have to get those videos uploaded here sooner or later.
With the M4, which I actually sold a few months ago, I was able to go much faster, its just a better car all around than the HellCat.... Although just before I sold it, my buddy and I took the cars out to Mexico and the HellCat was just a tic faster. Had I been running the 100 octane tune on the M4 I think it would have been pretty even.
