Not to knock your setup, but what is wrong with the OEM brakes? With good pads and stainless lines, and MAYBE some power slots, the OEM brakes are good enough to lock up azenis. Are you looking to track this car? Even if you are, there are a lot of race cars, ITA comes to mind, that are running rear drums! I seriously think oversized brakes are more for the look than anything, and you are adding rotational inertia as well.
