Hello CSSM, I'm quite new here and haven't really posted much but these sigs are hella tight. It'll be great if I can get my own. You already have a set premade for a previous post. (If you still have it) But mine would be quite similar so I'll copy and paste his post and make some changes.
BRZ Based
✔ Asphalt Gray (Dark gray metallic)
✔ 86 front bumper
✔ 86 Fogs
✔ TRD front, side & rear (put in black to contrast the gray)
✔ BRZ headlights
✔ BRZ vents
✔ Ducktail
✔ Reddened Tailights
✔ Lowering kit
✔ Larger exhaust
✔ Red calipers
✔ I know you don't really do aftermarket rims, but I can't help but noticed that you don't have any rims similar to Gram Lights 57s

You don't need to rainbow it, but if it's possible that'll be tight. But if not, you could just put it as gunmetal with red lugnuts.
Thanks a mil

+ another mil from me

CSSM!
Oh and thanks to GZE2 for the original idea post.
YOU'RE AWESOME!
