My '23 BRZ just came in with Magnetite Gray. I've watched the videos since your first install / DIY video, and love the new videos too! Followed on instagram!
Hi, it seems like it's not available in the states yet. You can get it from Black Hawk Japan. For the GR Aero Stabilizing Cover, it is only availble in Gloss black. You can get them from IRR, 86works, 8speed, FTspeed, etc.. If your looking for a matte black finish, the Max Orido one is for you. But I also see some people who paints their GR one to Matte Black and puts a GR logo sticker on them. Hope this info helps!
