I disagree. Unless Momo or FIA pulls the FIA certification on that seat (a la Corbeau circa 2003, due to failures in design) then that seat retains its certification. The only time that the earlier seat will be unusable is if SCCA chooses to enforce the 5-yr life limit; at that point even the 2007 design seat will not pass muster eventually.

If you're implying that Momo has already withdrawn the cert on the earlier bottom-mount seat (which would be news to me) then that seat is no longer usable without a back brace.
