I personally have had bad experience with my G35 with a Seibon hood (hood latch broke off and caused $7K worth of damaged, nothing covered, not even an apology, and they blamed me saying that I didn't use hood pins, which is the exact reason why I bought the hood because they told me the fitment was so good that Calvin Wan wasn't using pins on his FormulaD G35 half the time).... ANYWAYS... this is MY personal opinion, not my company's.
As far as my "official" opinion... I say, why not go for something more original and high quality? Something you won't have to worry about quality, functionality, testing, fitment, finish, durability and weight savings?
Varis makes a great hood fitting the style you're looking for. Give us a call or pm if you're interested.
