A friends selling a sparco evo FIA seat. Rules state 5 years or 2 extra if you send it back in for recert. I'm not racing with any real organization so rules don't apply. But I want to be safe. Good idea or no? Marked is may 2004.
From FIA standard 8855-1999 (revised 2003), article 7 (
http://www.fia.com/resources/documen...ion_seat.pdf):
7. Seat life:
The usable life of an FIA homologated seat will be 5 years from the date of manufacture indicated on the seat label.
An extension of up to 2 further years may be authorised where the seat has been returned to the manufacturer for re-validation. Extensions will be indicated by an additional label affixed to the seat identifying the date on which the seat eligibility (word missing in document translation) and validated by the manufacturer's quality inspection stamp.
