Donate one thing about the difference between U.S. spec FD's and J-Spec FD's
Japan five speeds had an optional 4.33 gear on some models, US is always 4.10 for a manual. The Kouki models have different/better cooling fans with 5 and 4 blades instead of 6 and 5 like the Zenkis we got. Later RZs had bigger front brakes as well.
