Just adding if anyone cares
Also to note, the rear bumper/ diffuser for the 86 (Kouki) is slightly rounder near the end (where the mudflaps goes). I actually replaced my 13’ FRS bumper for a 17’ 86 bumper, and I couldn’t apply the mudflaps to it. I had to order the 17’ mudflaps due to the different shape
The 17’ BRZ seems to not have adopted the extra line that runs across the diffuser like the 86. At least that’s what I noticed. Not sure why, need confirmation.
*edit: @
Tokay444 I'm sorry, I don't mean diffuser, but I meant the black bottom part that houses the reverse lights and holds around the exhaust tips
