LSD anyone?

[spy54]

so for 300 bucks would the phantom lsd be a good buy?

[ricodemus]

apparently the phantom grip "lsd" isnt really a lsd, but works like one. I did a quick search and seem to not have run into anything too negative, but google makes their money by putting advertisements first on search hits. I would do some hardcore web searches and see what you come up with.

Yeh ricodemus is rite. Do some more research on those. From what i heard that it tears ur tranny apart. I don't know if its true but my best bet that i would ask someone who has or had one.

damn for the price i would just by a lsd equipped tranny..... either way don't go phantom, it's pretty much like a locker, it'll work great off the line, but kiss cornering goodbye, when you are making a turn both wheels will get 50/50 torque instead of whats proper 60/40 or what have you..... or that's how it was explained to me.

I haven't heard anything negative about the Phantom Grip, but a 300 dollar LSD seems to good to be true.

The type-r has a torsen limited slip, i don't know who makes it. The other limited slips (all factory non-type r trannys) are usally made by hitachi, they are totally different. They are clutch pack limited slips. Hitatchi is the OEM diff supplier to most japanese carmakers. They also make the performance clutchpack diffs but they are based on the same housing as the open diffs so they are cast and have only 2 pinions. All of the aftermarket clutchpack diffs (kaaz, cusco,ats) CNC new 4 pinion housings so they have more space inside for largers clutch discs. They are less prone to failure since they were designed from the ground up as LSDs and build up less heat. For the street I would recommend an aftermarket 1.5way clutchpack diff or a torsen. If you find a good deal on a jdm lsd tranny they are worth it but remember that clutchpack diffs wear out and you should try to get a rebuild kit (viscous and torsen diffs should last a long time). I have heard some bad things about phantom grips but they are so damn cheap (i have seen them new for less than $200) that it might be worth it to some people. I hope that this helped.

yah when my tranny shits i'm just gonna find a y1 w/ an lsd already in it, i can't stand the massive torque steer my car has.

i very highly doubt it's torque steer... hondas do not exhibit torque steer. it is probably a loose suspension component or bad alignment.

in order to have torque steer, you need to have torque.

111ft-lbs in a 2000 lbs car is NOT gonna give you torque steer, especially with equal-length half-shafts like what the B16A trannies have.

the primary difference between the 3 is this:

clutch-type: cheaper, but wears out quicker due to the friction-lining based nature of them (think of it as, of course, like a clutch or brake pad). very effective, however. very good all around LSD

torsen (or gear-based LSD). not mechanical slippage so there is no wear like clutch types. very expensive (compared to clutch type). for street duty they work.. if you are gonna drag race i would recommend a clutch type. with hard launches, sticky slicks, and a strong clutch, you can actually break the teeth on these types.

viscous: they use a thick fluid.. kinda like a heavy oil to lock the drive shafts. they have the long-wearing properties of a gear-based LSD, but without the pront to breakage under high load. these will be the longest-lasting type of LSD. they are very expensive however (moreso than gear-type), and they usually end up "hunting" for traction leaving the car to wander under hard throttle.. or causing a delay in shifting power to the outside wheel. because of this they are not as effective as gear or clutch type lsd's, but they have the best longevity.

our 1997 Nissan has a viscous LSD in it from the factory.

the ITR and new SE-R both have gear-types, but most other factory LSDs are clutch type.

hell.. even the porsche 959 had a clutch-type center differential.
