I've been searching through the threads and haven't found a whole lot on the stillen rear diff cover. I've done my research and I know that it will bring down the temp and increase my fluid levels but what I can't find is a DIY thread. How hard is this mod? Has anyone actually done this themselves and if so is there a thread out there? Really want to do this mod but I want to do it myself. Any help here would be awesome!
