1998-2002 BMW Z3 M Roadster 3.23 Ratio Clutch Type Limited Slip Differential. Removed from a 1998 BMW Z3 M Roadster with 122k miles. This differential has a final drive ratio of 3.23. In good working condition, fully tested prior to removal from the vehicle. Differential made no odd noises or grinding or testing. During testing we did notice the passenger side output flange seal was seeping some fluid. We suggest replacing this seal prior to installation. Fluid has been drained with no abnormalities. Will ship drained of fluid. Includes the axles stubs as shown. Housing is in good condition with no damage, all mounting tabs are fully intact with no damage. The rubber mount is in good usable condition with no rips or tears. The housing has some spots of heavier surface rusting and corrosion as shown. You will need to reuse some of your existing hardware for installation. This style differential was only found on M Roadster and M Coupe models. Includes the finned rear housing as shown.
