I see Cusco Japan have just released a solid replacement for the diff pinion OE collapsible spacer. Could be a worth mod if you're planning on keeping the OE Torsen LSD & it's going to get a regular hard time.

Has adopted the "crush type color" is genuine parts, is the color to change to shimming type this. It is possible to prevent damage to the differential unit without parts deformed even after repeated running hard by a "shimming Type Color." This is the part that you are using for the position which is not visible from the outside, but because it is a part that has taken all of the input from the tire side and the driving force of the engine, it is very important.
It does not pose a problem if only the normal running in the normal state, but from factors such as the following, stress on this component will increase even more in sports driving. <Load factor to color increases>improved traction by wearing · LSD increase of engine power installation of the high grip tire increase of the braking force due to installation of a high-performance brake pads , such as gymkhana and circuit racing, sports driving improvement of the drive transmission response by attachments such as the clutch and strengthening etc ....
