I wouldn't mind spending that kind of money for the trans, but my friend has ran into an issue on his CD009 setup that has made me put the idea on hold. Basically the 009 won't fit in the stock shifter location and uses a u joint to shift or something? Not sure, either way he threw engineering gibberish at me involving some weird shit about the shifter. He says what he has done won't work, but it seems to work in my eyes.
Others have done it but his pride won't let him ask, I'm too lazy and I'm not too worried about it right now, my rear diff Will pop before the trans....I hope.
