There are a few LSD's you can go with. Kaaz and Mugen are clutch type so you'll need to replace the discs a bit if you are actually road racing. If youre auto-x'ing, you could be safe with any type lsd, but the clutch types wear faster I think. Then theres quaife, stock honda, ats (carbonetic) and I think toda has one too. Your best bet from what I have been told for a somewhat daily car is the oem one or quaife.
There is also OBX, the cheapest, but I have read mixed things about them. Look around on here and see what different people say for different purposes.
