GT-R SPECV '09 600PP for Nür seasonal

[voltctrl]

I designed this with the 600 PP Nürburgring New Year's Holiday Challenge 2012 in mind. This is not a finished tune, it's my fifth one or so, but the difference in performance from the GT-R '07 GRIP tune i used the power limiter to get into the race was so great I thought I'd upload it. I'm no great driver, but it took me from 8th place to 5th on a DS3. Feedback is greatly appreciated.

Happy New Year, GT community!

Cosmetic:
Atomic Orange Metallic Tintcoat, or a similar metallic orange

Stage 3 chassis weight reduction
Window weight reduction
Carbon bonnet (unpainted)
Rigidity improvement
All aero parts, rear set to 22
[YMMV] Ballast: set it so your balance is 51/49 f/r. This is what I used to keep it in the correct PP range, as it fluctates slightly. If this is a bad idea, please tell me!
