Has anyone used the MMR composite windage tray with the mmr billet rear main seal housing? Have you had any leakage issues with the 2 combined? Is it worth the cost of using the MMR windage tray vs the OEM 03 04 Cobra windage tray? Is there that much turbulence through the entire oil pan warranting the need for a full length windage tray, with 14 to 16lbs of boost compared to the stock 8lbs of boost?
