The main benefit of a stub axle setup comes with giving you the ability to change a half shaft twice faster than oem. Often that`s crucial during races because a 5 min shaft swap might turn in to an hour because of an old hub spline or nut that got stuck. We have these available for the most popular Motor-Sport 122mm CV joint sizes. NOTE: These stubs fit only 30z hubs (the so called big bmw hub splines). Feel free to email us with your desired chassis / knuckle combo. We make these custom with 1-2 weeks lead time. NOTE: For the moment these do not feature an ABS ring but can be added for additional payment
