I'm sitting at a vendor's shop as I type this waiting on them to install their newly released solution. I'm going with what they call their stage II which is larger pan that holds 4 additional quarts of fluid and replacing the stock cooler with a more efficient cooler. They offer a stage III which replaces the pan and instead of simply replacing stock cooler keeps it, but puts in line with the stage II cooler. Stage I is just the larger pan.
