If you want shorter ratios, look at importing a CL7 EuroR gearbox from Japan instead. That will have your shorter ratios and the LSD already in it. You need the right gearsets which might not even exist for the CL9 transmission case because mixing and matching will give you the wrong tolerances on the mesh of the gears which puts stress on the gears and cause premature failure.
DC5R most probably won't fit on the Euro. The gearbox is a different size and the mount might not match up with the transmission mount on the Euro.
Yes, i have gone to Wakefield with the LSD. It's great for track.
