One other very important factor to note. Everyday drive-ability.....if you daily, or drive the car to and from the track, going with a super high performance, high locking factor LSD of any kind, can be down right diabolical in rain conditions on public roads.

My Guard LSD was incredible on dry track, but if it was raining on public roads, you better have two hands on the wheel, it tries to kill you.

This again, is why I prefer low-pre-load LSD's...and perhaps the Giken most of all for dual purpose cars, because it gives you good DD capability, in the event your car isn't just a track whore.

If you feel your stock LSD isn't locking enough, before buying a new unit, perhaps just run some non-LS gear oil, and you should feel it grab faster and harder than before. Our diff's don't have external coolers, so the gear oil gets plenty hot. Most gearbox builders will tell you for track applications, to just skip the "LS" oils, because at high temps they make the clutch plates too slippery and you lose lock. You can go as far as even mixing 50/50 with LS and non-LS to tune it better. Cheap DIY LSD tuning.

Just something to keep in mind as well.
