Love that car!
The JWT wont make too much differnce man...but it looks nice when u pop the hood...but u cant hear it that much. Also, i LOVE the 06 headlights...the projectors look very nice.
Great pick.
I only have one bit of advice for you (i have owned 2 G35's)
Unless your gonna spend $10,000+ on a turbo kit, DONT waste your money and time playing around with bolt-ons. The VQ wont respond all that well (maybe get u like 20hp) to mods like intake, headers, exhaust, plenum, etc.
Instead, spend your money on the suspension, wheels, and enhancing the cars #1 attribute- ITS LOOKS!
Ok, my rant is done...thats just my $.02
Enjoy your new G
