I like the flip idea. Sort of like rotating your tires to even out the wear over time.

Now what is so special about these radiators to warrant the $800 price tag? Yes I know it's a Porsche part, but we're talking aftermarket on a 50,000+ production run car.

If I had a higher mileage "just for fun" 928 that I wasn't worried about originality on, I'd be retrofitting a brand new universal performance type radiator. Used is just asking for trouble and probably as much as a new universal.
