I have a b20vtec mated with a jdm gsr w/viscous LSD. Apparently it was worn out and I broke it and the wheels spin independently like there isn't lsd anymore, It doesn't engage like its intended to. I am currenly rebuilding my trans with Mfactory LSD and carbon coated syncros from syncrotech. And also putting ls 5th gear, ls final drive and ls RG and CS in as well. I wanted to know if anyone has experience with this diff and what their opinions are of it. I got the gear type maintenance free life time warranty one. Just have to change the fluid. Anyway whats your thoughts/opinions. Thanks.
