I never really liked the stock trans all motor. Especially 3rd gear. Granted I would pull away from a lot of others but I could only imagine how fast the car would run through the gears with this final.
ouch! 4k at 70mph...that high for a daily driver ...
I dont think the OP is doing this any longer. I would say your best bet is to get in contact with mfactory and see if they would be interested in doing it. I would be out of this though, I ended up buying a new final drive.
