Wow looks amazing. Very aggressive. Looks well put together with all of the parts.
It seems like you daily drive your car, so do you worry about the hood popping up while driving?
Of all the carbon fiber and vented carbon fiber hoods I've seen on Club Lexus on 2IS and IS F, none have used hood pins.
Also, what about rain getting into the vents?

Looking awesome dude! 
Definitely the way I want to go with the hood/bonnet as we call it over here!
I noticed someone asked you what you do about the vents allowing water into the engine bay? Any answers on that one? I'm just curious whereabouts the vents line up under the hood?
Only real thing that could get water marked on mine would be the oil filler cap and the Cusco front strut brace.
Does set things off really nicely though.
What else have you got lined up for it? Think it's pretty awesome as it stands!
Cheers.

As far as next mod, maybe equal length headers and I'll hold off for a few months. I have been modding like crazy

This is not how aerodynamics works. Airspeed over the hood reduces pressure on the top side. Static air underneath the hood causes lift because the reduced pressure on the top from forward speed creates an imbalance. The faster you go, the greater the lift. Air "getting under the hood" is not what causes the problem, and there is no way to stop air from getting under the hood just as there is no way to slow the air over the hood without creating massive drag. Suffice it to say, the OEM mechanism to latch the hood is strong enough to deal with the lift the hoods make - OEM or aftermarket - without hood pins. Actually, because of the vents on the Seibon, there is probably less lift than the OEM hood because the vents cause the air to stall and increase pressure on the top side.
A proper splitter works exactly the opposite - fast moving air underneath the splitter creates low pressure on the bottom while the stalled air on the top side creates higher pressure. This is what makes a splitter create downforce.
If you stuck some inch long pieces of yarn in a pattern around the vents, you might very well be surprised at which way the air is moving on the vents.

I went to European Auto Source, EAS in Anaheim, today to dyno my car before testing out the Vivid Racing tune. EAS is very big in the BMW M community that dyno many M cars. I'm curious on how my numbers vs the M3/4 on the same dyno. Darron tagged along to check out my car on the dyno and he got the itch so he put his car on the dyno too for numbers. GoPro video to come
My car, 08 107k miles with Meisterschaft exhaust and Sikky headers. Light weight two pieces Racing Brake rotors and TE37 19x10.5 wheels if that matters. Here are the numbers my car pulled. 4th run, the last run, gave the best numbers actually. The car seemed to pull harder and harder after each run, and the dyno numbers backed it up. Run 4 was imidiately after run 3 so there is no cooling down period in between.
DYNOJET 91 oct California fuel
4th run, 404whp 382wtq
Darron's car number
Mods, Sikky headers and Joe Z exhaust

Traded. Steering ecu is still calibrated with the 2012 car that it came from. Even with that, it felt much more precise than the 08-10. It was actually sloppy/loose the first 30-40 miles and then the steering wheel seemed to adjusted/learned and got so much better. At least that's what it felt like to me

Thanks bro! I think the red seats is the best mod I have done. Softer cushion for my bottom and so pleasing to the eyes whenever I'm in the car. I can't see my exterior mods lol, that's for people around me to see.
