I haven't been able to figure out if there are tuning kits available for the F56 JCW (or any JCW). Maybe they have a special name or maybe they don't exist because the only search result I get are JCW tuning kits for the Cooper S. I figured it wouldn't hurt to ask the people who would know for sure: Are there tuning kits available for the Mini JCW's?

 

Just the JCW Tuning kit here, which is for the Cooper S: 11122359631 Some people are just using the exhaust part and not flashing for the tune but for the exhaust.
