When installing this product on RWD Chassis

When changing from the standard bevel gear (16T) of the GRK GLOBAL series (including GS2EVO) to this product, the [R31W269] GRK GLOBAL RWD reduction gear adapter is required.
When changing the bevel gear, the clearance with the ring gear of the differential will change, so adjust the backlash by replacing the shims on the left and right of the differential according to the current car.
