ALso dont read one thread on some site, where one guys says he has heard of lots of people having trouble with it. Cos infact, they dont. PPl have learnt from the first few times, and if u look properley, you will find that all a d-series guy has to do, is shim it correctly.
Helical is preferred for racing?? wtf are u on about? DRIFTERS??? Look at the top track cars from Australia, USA and Japan. You think they use helical? NO .. why? because it lacks response and locking power.
If you bothered checking the inherent design of a clutch type LSD vs a helical, the discs provide greater locking power and more responsive engagement over the gear type diffs.
Why does Honda use a helical diff? Because its lower maintenance, lower cost, a mass produced item that is easy on everyday driving. We wouldnt want a chattering diff. for a factory car would we?
Quote: "you will find that all a d-series guy has to do, is shim it correctly' the fact that you have to shim the POS obx unit and it does not plug and play, shows testament that the quality control and development of this item is below par. What type of company produces an item that doesnt fit or operate correctly? An EBAY company.
This is the reason why I dont wish to waste my hard earned $$$ to 'try first hand', because changing a diff. isnt like changing brake pads. I would rather spend the money on something proven and not fix things twice.
Go figure.

meh let them try OBX and find out 6 months later that they need a new gear box and LSD i say.
Then they may work out what the cheaper option really was

a helical diff works by biasing torque from one side to the other side. they are able to transfer more torque to the wheel with traction. that's why the are so good for road racing.
Why do we need a diff that fully locks? I know drifter do (hence why mentioned) or atleast one that doesnt move around the way it transfers torque
Heres some info on diffs

a little quote from 'Quaife'

Because it behaves like an open differential during ordinary driving, street drivers will have trouble telling it's there until pushing the car's limits.
I will look for more info if i u wish....

What are you saying? I've just said I've been using an OBX LSD for over a year, and have been tracking it as well. There's nothing wrong with my gearbox and I even just use normal gear oils that I've bought from the shell servo.
and to top it off, I actually have a D Series LSD in my B series Box, had to machine the plate to make it thinner (Which should mean its weaker right?) but still am not having any problems.
My point is, not all cheaper things are crap, not all expensive things are good.
In my experience, the OBX LSD are bang for buck having already tried it. Would I buy an OBX LSD again? The answer is yes...

cool hope all goes well, however i am sure i can drum up one bad experience for every good one.

Just get a the OEM prelude ATTS. They works like an LSD. Do some research. They came optional on preludes and standard on prelude type S.

problem is alot of you guys just think that there is ONE great lsd and thats it... rest are shit... no questions asked...!!
easy enough to say... but think about it when your shopping for something... you have to think about budget, application/type of use and i guess abit of bias thoughts...
different type of lsd's are for different applications etc... just a matter of research and knowing which one you need... some people prefer clutch type because they're cheaper, but doesn't mean they're less quality... fair enough in the long run they do wear... but depending on the driver and its use, it could outlast the car and was no need to spend more on a helical type!! others prefer helical type because of they're longer lasting guarantee... but you could get one of them, not treat it right and doesn't last as long as a clutch type...
only reason brands get reputations like about the OBX lsd, is because on the net, ppl only like to make an issue from things going wrong, not going right...
i've got a mate whos running a phantom grip lsd in his sr20det... i haven't heard one good thing about them on the net, but he abuses the hell out of it, and it still runs fine...
like e240... hes been tracking an OBX and it seems fine... obviously doing something right...
i could be wrong... but thats just my opinion...

Well a $450 LSD compared to a 1.5K LSD there must be something different about them?

Quality assurance right there

I'd wonder about the amount of effort put into metallurgy by the manufacturers of the cheap-o units compared to the expensive ones.
Copying the dimensions and machining the right size gears is one thing, using the right compounds, seals, bearings clearances and whatever else is another matter entirely. Well, thats my take on things.
