I'm about to make a purchase of a ITR LSD to pop in my GSR tranny. Are there any other parts I need for this conversion (bearings, etc.)?

Thanks

 

bearings yes.
install the LSD and check its fitment side to side with a feeler gage.
then order the correcr spacers/shims from honda.
may take a few days to get them.
I was lucky and able to use the shims from the oem differential with a little machining. that may be an option for you if you know of any trustworthy machien shops that will do it for free... grind off .005" or whatever.

also need hondabond to make a nice seal when you bolt the tranny case halve together again. Make sure you have the right tools ahead of time!


you will the LSD, I know I do

 

go with the quaife over boost . com sells it for 850 its better then the itr diff. plus its life time warrntied so in my mind go with quaife plus you dont have to buy anything else dont get me wrong i love the itrs and all but i have a several friends that tell me that their quaife handles much better than the factory lsd.
