after 9 years and 45K miles my 996 TT drivers seat base would appear to be sagging a little (I weigh 95kg/215lbs). Can the base support be refurbished/reinforced in any way. I need a heated seat in winter and have previously had a GT3 Seat but its not really fab as a daily driver in winter. Pity you cannot switch the passenger and drivers seat / base as the passenger seat has had 10% of the use.
