Nismo N2 should look a lot better, not many people are a fan of the ibherdesign venom bodykit, but each to their own, not seen that spoiler before looks might even hunt for one like that.
I have similar mods to you and only made 283bhp, so would be interested to hear you findings on the compression test. But I think the engines just loose hp quickly over time or were lacking it in the first place.
Cant you just buy some carbon wrap and cut out the shape you want and stick that to the headlight rather than pay lots of cash for eyebrows that have been known to detach
Might do this myself come to think about it
