I don't see the rocker switches on the lower plastic panel for the power lumbar support and side bolsters. The power articulated type of seat is what came standard on the Trans Am WS6 package.
I have seen some 99-02 Firebirds with a performance package that had leather interiors but without the power lumbar/side bolsters. The seat in your picture may be from one of those.
But to answer your question, no I don't think these seats are correct for your WS6.
