Perhaps you can answer a question. What do the OEMS do that use 2 piece rotors? Are they special in any way that makes them usable in 4 seasons? I don't recall any of them using full race calipers, most seem to be the "street" version 4 or 6 pot so I assume with full dust boots, etc.

Thanks, me too! OEM's many times use a one-piece disc when running a fixed four or six piston caliper, for both cost savings and for the 4 season durability reasons. Some good examples are the Evo VIII-IX, STI, 350Z Track, C6Z06, etc.
Two-piece discs from the factory are fairly rare. A good example would be the Nissan GT-R. They use standard Brembo factory mounting hardware/spring clips...the same parts you find in one of Brembo's aftermarket GT kits. The typically address the issue by having some qualifying language in their warranty to warn people that the brakes are high performance parts, and as such, you need to be more mindful of maintaining them. For the GT-R, they even have a disclaimer for the brake pads in the owner's manual, stating that they are a high performance compound, and that they may make noise, squeal, etc. The car is so targeted in its appeal, that they are assuming the customer would rather have the performance and deal with the slightly greater maintenance. I believe it was a smart choice. Most of the owners only use that type of car in good weather, and even if they don't, they don't mind spending a little extra for the added performance benefits. As for the calipers...yes, they are not full race calipers from the factory on these cars. They all have dust boots on them.
