Those seat pans of Radeks look to have similar setup to the DA9 Tegs where the outside rail is outboard of the seat pan, so if that's what your ED6 is like then, No, CRX seats and rails won't fit. I fitted DA9 seats into my CRX, but I had to use the DA rails and make mods to do it. If you want to stick with Honda seats, the Gen3 Preludes look like they've got great side and leg support, but don't know what's involved with the rails. Would also be hard to find.
