To further complicate matters on this. Mighty Car Mods GRY did NOT have the Performance Pack, IE the factory Torsen diffs. So could that be it? PP you get brake ducts, non-PP cars don’t get it?That's what it sounds like. With the GR Yaris, it is pretty easy to buy then and convert it based on Mighty Car Mods's video.
We all are. It would be good to know the venting situation on every trim. Core, Core w/PP, Circuit, and Morizo.You bring up a very good point. Now I'm confused again.
