Thanks for the comments guys! I had no idea I have a brake duct missing. I looked at it again this morning and it looks normal to me! Bummer if I do have something missing!
Aki, I know Nakane-san well. He used to work at Zele. He is a really good mechanic. He opened his GT-R maintenance garage not too long ago and I thought I put on one of his stickers on the car. I hope it can help him out getting more business. And that's where I take my car to for maintenance/ repair.
