G37 Coupe seat adjust?

[ACoupe]

Over on the Fresh Alloy forums, a user posted a trick to lower the seats in the G35 Coupe past the factory lowest setting.
Has anyone tried it on a G37 Coupe?
I'm looking at a G37 Coupe next year when the lease on my 2007 G35 Coupe is up but am concerned about the lessened headroom in the G37...

For some reason after driving 240s for ever, when I got in the coupe, It did feel like the roof was MUCH lower.

I have my seat all the way to the floor, and I'm 6'0 with plenty of headroom.

The seats sit pretty high. Makes for easy exit, but not great for any race event requiring a helmet.
