suitability of lsd

[Jason240sx]

did my thing , already searched and read. end up with the conclusion below

for grip:
go hlsd or 1.5 way

for drift:
2 way.



is there such thing like a in between? i take my car to autocross , road races and hopefully drifting events.

i was so tempted to get a 2 way but was afraid to have the rear end too loose.

any help from experienced owner appreciated

[infinitexsound]

go 2 way, its better regardless...

[!Zar!]

2way is better for grip and drift.

It's just that if you suck, hlsd and 1.5 is a little more forgiving.

If you learn how to drive properly then you will have no problem with a 2way.

[redsuns3838]

theres no inbetween for 240s. I've heard of other cars having 1.X lsds but they dont make any for a 240 that I know of. and like they said, if you learn to drive, 2 way will be best.

[Jason240sx]

i've gone through most thread and i forgot who is who but mostly i can see post like " if i were to do it all over again i'd rock a 1.5 way for a DD"

is that because of the clunking noise or something? and since a clutch lsd needs to be rebuilt , the only way to tell if it needs one is how much it locks? i dont see any rebuilt kit for sale too

[infinitexsound]

its the noise issue, mainly you drive with the music up anyhow so who gives a fuck.......... tires chirping... if guys can rock a welded diff and not care... then what..... you have money to opt for the real deal... then get it... dont bitch out and get a 1.5... get the 2 way... its still worth more in the long run...

[Jason240sx]

alright thanks guys , any different between a tomei , ats , kaaz , nismo out there? cause all this i see the review from people and i think it's so subjective to comment on each. just like is there a main difference among any of it.

on average for you guys weekend track people , how long do u need to rebuild. and what is consider a lsd rebuild?........

[ronmcdon]

i can't speak for drifting, b/c I'm not into that. however, whether you choose between 1/1.5/2.0 way or helical is really more a matter of preference in driving, and whether or not you mind dealing with the clutch lsd clicking and maintenance.

what do mean by something in between clutch based and jelical based? iirc, they function in completely different principles, so i dont see how it would be possible to have anything in between. pls read this for a basic explanation; http://en.wikipedia.org/wiki/Limited_slip_differential

anyhow, with the clutch lsd's, some engage more smoothly than others. the ats carbon, nismo, cusco rs (?), are some of the moore smoothly engaging clutch lsd's. helicals almost always engage smoothe and don't clatter.

personally, i like helical lsds. i have a quaife lsd on both my s14 and my eg civic hatch, and they do their job very well without the clatter and maintenance of a clutch lsd. this is good for me, b/c i'm too lazy to bother with additional maintence and my s14 has more or less become my dd (there's already enough annoying rattles as is). its also prob the only option thats warranteed from track abuse.

there really is no better or worse choice imo. just try to find and drive around in cars with the said lsd options. decide for yourself what you like. If you dont have a lot of track exp with your car, imo its best to go with a more forgiving helical or 1.5 way. as for me. regardless of how much seat time i have, i will always suck. so perhaps an idiot-proof helical would be the best match for me. btw - not claiming to be an expert, just sharing my thoughts and exp for discussion.

i have a Tomei 2 way, and its really responsive.. i recommend it through and through...
as for Kaaz i know alot of people who have the 2 way Kaaz and they also recommend it...
the Tomei is more agressive i would say.
also i hear great things about the Nismo...
but i researched and found that the Tomei is a better buy for me...
plus theres a kilelr GB on them right now

[chmercer]

2 way is the best differential for general use
spool is best for 100% dry grip, 2 way is better for rain though, irrelevant for street/drift cars though

hlsd and vlsd are crappy compromises for "sporty" street cars

helical diffs dont engage. there is no clutch in a helical.

a hlsd will break before a clutch diff.

hlsd is stupid because it randomly biases torque depending on load so its totally unpredictable, plus you will still get stuck if you pick up a wheel on a driveway, since it will still bias all the torque to the wheel in the air, like an open.

i probably missed some stuff, maybe somebody else can jump in here and clean it up

[Jonnie Fraz]

If I am reading this right you are looking for a lsd that can be used in 1.5 and 2 way. If so check this out.http://www.cusco.co.jp/english/e_lsd.html With the Cusco you could set it up as 1.5 way to get used to it nd later change to 2 way if you like.

[chmercer]

nobody on zilvia has the mechanical ability to change the clutch disks on a differential let alone the locking characteristics.

[420sx]

do the 2 way. never regret

[Silverbullet]

Jason240sx: ride in a car with a 2 way diff first before buying one. They are noisey and harsh. A helical LSD would be more suited if you daily drive your car. It's great for autocrossing and road racing. If your not considering competing in Formula D anytime soon, you dont NEED a 2 way LSD.

[CA18_S13]

2 Ways are way cheaper cause majority of people go 2 way. 1.5 way is more expensive in what i have seen on kaaz's website and other websites. 2 ways are noisy but when they break in for the most part you don't hear it or you get use too it. 1.5 way is good for drift you just got drive differently then some one with a 2 way. 2 way for the win.

hahaha no no you always hear it like going through drive thrus, thats terrible haha
and slow tight turns

+1 For the Tomei Trax Advanced 2-way

error. inferior

[wootwoot]

how is a HLSD inferrior for Autocross? It is one of the best types for that driving. With low speed turns the front end wont push as can happen with a locking diff.

Helical/torsen/gear based LSD's are known to be be some of the most reliable. Are you simply spreading misinformation because you personally do not like them?

[zoototheyork]

how often do you have to service them?

[wootwoot]

how often do you have to service a gear type? 40k miles to change the fluid.

How often for a clutch?..Depending on the brand, driving, tires, fluid used, how often fluid is changed, what the configuration of the differential is..Somewhere around 30k I'd guess for most?

[zoototheyork]

oh nm 30kif you dont beat the shit outa it everynight? like 10-15k then?

you sir speak the truth. 2ways are harsh for autoX

My guess is he has never used one and is simply regurgitating crap he has seen posted, so he doesn't understand why what he is saying is wrong.

The problems that he is describing is caused by a poorly setup suspension, in which case a 2way is probably a better bandaid for that.

"Stuck on a driveway" Has that ever happened to anyone other than "I had a friend once"?

I used to get stuck going up my driveway every now and then with my open diff. After I installed my HLSD, that problem was pretty much gone. The HLSD may act like an open when one wheel is in the air but it is not nearly as bad as a open diff.

[250sxdet]

I have an ats carbon 1.5 way and i totally love it. It locks really hard and there is no noise or clunking at all. carbon lsd's FTW.

speak for yourself guy, im sure you offended more than a few people on this forum with that coment. not everyone here is moron.

[PoorMans180SX]

Like 250sxdet said, just put the money down and invest in a Carbonetic 2-way. 2-way locking without nasty clutch noise. Problem solved.
