From what I've gathered, the E1 calipers will "work", but won't give as much braking surface, as they aren't as tall of a caliper as the FSVT's.

Rara has verified that an E1 caliper will work (from the pinned topic) but has anyone tried using a E0 caliper on the FSVT rotors?

You can use the FSVT anchor bracket with the contour caliper. The only differences from the full FSVT brake swap, is you pull the stock anchor bracket out, and slide the FSVT one into the stock caliper
