thanks for the response. I'm currently debating between this and a quad diffuser.They fit like all other carbon fiber does- "ok". Expect any carbon piece to need a little massage. I put a vorsteiner on an F10 and i expected for the $$$$$ for it to fit like a glove...... which it didnt.
its a molded in bump. not an anomaly
New.
250 sounds good? gonna have to package the hell out of it to keep it from being damaged
