I have seen 2 kits using Eribuni parts in them before (neither were for a Scion). One kits was for an Integra, another for a Mustang, both kits used some Eribuni parts and some from other manufacturers. The Eribuni parts I saw were the worst pieces of trash I have ever seen. The Mustang kit got returned the integra kit got used but the Eribuni hood (didn't fit the opening, was softer that paper machette, had 1/4 inch deep waves in it) and 3 lip pieces went in the trash (that is how bad they were). Does Eribuni make nice parts for the xB??...who knows but after what I have seen I would touch nothing Eribuni unless I had already seen it and knew it was good (or the seller would deliver it for inspection and pay both ways shipping with no penalty for return if I didn't like it).have you seem the eribuni kit in person.?
