Welded differential... lets talk about it. We welded the diff in my BMW drift car a number of months ago and I wanted to share my thoughts on it after daily driving it for awhile. In all it's a fun and cheap way to get your car drift ready but it comes at a cost. If you plan to track your car a lot you won't regret it but if you plan to daily your car you might regret it some. Take my experience and use it to help guide your decision, thanks for watching!
