Diffsonline Spec E46 Racing Differential


Premium racing limited slip differential for the SpecE46 class.  This is by far the most popular differential option for SE46 cars.  Nothing to set or think about, just install it and go.

While the SpecE46 rules allow for any 3.46 ratio differential, you’ll be hard pressed to find a better option.  This is the same differential found in the majority of top winning SpecE46s.  4 clutch with 35/60 ramps with optional REM polishing.

  • You can find your production date on the black placard on the driver's side door jam.  This information tells us what output flanges should be used.

    $500 included core charge will be refunded upon receipt of your rebuild-able core*.
