Hi, I am Jonathan Paquette and I am BavarianDiffs, this Patreon page will be used to share with you my passion for engineering, machining, fabrication and rebuild of car parts, especially custom BMW differentials. Through my endeavor to share with you what makes my race-proven differentials so reliable, you will learn all my tips and techniques.
