Z4M roady @ T-hill w/ cyclone.

My best lap of the day w/ a passenger. laptime -- 2:14.35

06 Z4M roadster

Stock except...
Ferodo DS2500 pads
ATE superblue racing fluid
Star Spec 245/275 (39/38 hot)
camber pins pulled

I think I can improve the time a little more:

1) 2nd gear at T11 but heel-toe into 2nd is really pain in the butt.
2) better arch at T14-15
3) 2nd gear over T5 (???)
4) lighter braking or maybe just lift-turn-throttle at T8 (I always run out of guts here. I spun once at ~110mph right here)
5) need more guts and stiffer right foot on the throttle over T9. I keep missing the outer berm next to the big gutter. The cure is to carry more speed and it will push me there.

Please feel free to give your input...
