Treat your seat well and it'll last longer!
I did EXACTLY that (and THEN some), and the Recaro SPD (forerunner of their current 'Speed' seat) I had in my 2000 Z28 DISINTEGRATED within 3 years time (suspension broke and dropped out of the frame, Avus material wore clean through to the cushions even in LOW wear areas, and the cushions themselves crushed and deformed) and Recaro refused to either warranty it, OR even sell me the covers/cushions to repair it myself. About $800.00 plus a $175.00 Wedge base adapter thrown away.
Now granted, Recaro may care a bit more about their OEM contracts than the aftermarket, and therefore take much more care in materials and build quality, but they have lost me for LIFE as a customer, so NO, I REFUSE to pay a $2000.00 premium for their name on my seats!
I will eventually install my OWN seats in this car (Status Spas in alcantara, which I am told will be made in THIS country in the very near future, Cobra Daytonas in alcantara, OR Sparco, OMP, or Racetech shells IF I decide to go that way) once I figure out how to get around the air bag s**t.
