I got B18c in my Ek, Ek9 brake made be just enough but I don't want to change stud pattern and my wheels just like a lot of guys in here.

Wilwood brake calipers don't have dust cover, not ADR approve,

Second hand Spoon 4 pot calipers is the idea what I want, but too hard to find, also way over price.

Normal Ek Brake booster and MC is ok to use Rx7 Fc 4 pot brake calipers, I already confirm with my local engineering guy. Just need to find the way to do the fabrication.

I guess if I can do it cheaper the ek9 brake conversion, a lot of people in here would be interest. How much is the Ek9 brake conversion this day?
