Did some research and found out Porsche is having a recall on seats. Here's a copy and link to the information;

Make : PORSCHE Model : 911 CARRERA Year : 2003
NHTSA CAMPAIGN ID Number : 04V070000 Recall Date : FEB 16, 2004
Component: SEATS
Potential Number Of Units Affected : 1805
Summary:
CERTAIN PASSENGER VEHICLES FITTED WITH FRONT SEAT BACKS, WHICH DO NOT MEET PORSCHE'S STRENGTH STANDARDS.
Consequence:
IN THE EVENT OF A VEHICLE CRASH, THE SEATS COULD TWIST, TILTING ON ONE SIDE TO THE REAR, POSSIBLY RESULTING IN PERSONAL INJURY TO THE VEHICLE OCCUPANT.
Remedy:
DEALERS WILL REPLACE BOTH THE FRONT SEATS. THE MANUFACTURER HAS NOT YET PROVIDED AN OWNER NOTIFICATION SCHEDULE FOR THIS CAMPAIGN. OWNERS SHOULD CONTACT PORSCHE AT 1-800-545-8039.
Notes:
CUSTOMERS CAN ALSO CONTACT THE NATIONAL HIGHWAY TRAFFIC SAFETY ADMINISTRATION’S AUTO SAFETY HOTLINE AT 1-888-DASH-2-DOT (1-888-327-4236).

I imagine this is for the 986 too.
