Answer: None.

I won't go any of these routes in 2012. I will just enjoy the car with the great Dirrezzas as I have done before.
Wow Tony, instructor, that's great!

I was running my Dunlops at 45 lbs pressure when hot. They were performing quite well. I now have 13 track days on these tires.

Not sure where and when am I going out again.
First, good representation for the Z4 buddy!

The highest I've run hot is 42 lbs, and I've been shooting for about 39/38 lbs F/R hot. I didn't notice the tires getting greasy at 42 PSI, so I guess I could have tried a few more PSI.

You seem to be getting really good wear on them and have a lot of experience. What's your opinion of the 45 lbs hot vs. lower pressures (say 38 hot)? How does the car handle, impressions? I might start off with a bit more PSI cold next time and target a higher pressure hot based on your feedback--I guess I was under the impression 45 hot was "too high".
