Ah, How i missed this thread?
I was in same situation after i installed the TT kit, I had heat issue and it was seriously annoying so started with venting the hood.
I really didnt like any of aftermarket hood supplied to G37 coupe. so I had to steal a design from another world, BMW for instance.
After countess of hours research and see what fits taste I end up with vorsteiner hood for bmw 3 series.
And it all started from here (excuse my noob Photoshop lol)
Tada! Its not exactly what I wanted but looks similar atleast.
The funny part is the company that made my hood now calls it type s version 1 g37 hood (or what ever its called now) and sells it as their design without a single permission
After all this hood really works and looks good. Im sorry Vorsteiner for stealing the design but i had to do it due the lack of body kit available for G37 coupe
