limited slip question

[deezlins]

im guessing this is the right forum for this?

i know the difference between 1-way, 1.5-way, and 2-way LSD's, but why would you want the differential to lock up on deceleration (other than in drift)?

[chmercer]

you said why. noone uses 2 way for anything but drifting (to my knowledge), just slows you down, increases lift throttle oversteer.

Prevent lock-up of the rear wheels under braking to some degree.

[deezlins]

so really no use in getting 1.5 or 2 way unless you drift?

[240marcuSX]

1.5 way is the best of both worlds. 2 way is the one that is primarily used for drifting.

[deezlins]

How much does it actually help during braking? is it even worth it? Is there any other benefits? Wouldn't a 1.5way wear faster than a 1way?

[240marcuSX]

they arent really designed to help while braking, theyre designed to give you better traction when accelerating or turning.

Yes, its worth it. You dont have to worry about them wearing out unless you get a viscous unit.

[deezlins]

i was talking about a 1way vs a 1.5 or 2way, not a lsd in general. I meant was it worth it to get a 1.5 or 2way instead of a 1way, and was there any other benefits to a 1.5 or 2way besides drifting and a little bit with braking.So if im mostly doing grip driving, is there really any reason to get a 1.5way instead of a 1way?

To answer your question, no.

It sounds like were getting into a matter of preference now. To fully answer your question you may need to drive the vehice with 1 way and 1.5 way to see what you like. I prefer the 1.5way. To me, having the LSD funciton a little under deceleration seems better. If to help the car to rotate a little easier and provide some what equal traction for balance.

Clutch type LSDs wear out faster than Viscous units just FYI.

LSD's also promote understeer and can limit rear traction in heavy cornering.

LSD's just prevent wheel spin and the resulting overheating of the tires. Provide a smoother acceleration out of corners.

I did not know that. that sucks.

[skydragoness]

I'm going to post in this existing thread as to not be annoying.

But i'm interesting in getting a VLSD unit. I've read that the s13/s14 units are pretty weak (not literally)... would a J30 lsd be a better choice? I autocross/use my car for daily driving. So i don't think my application asks for anything nuts. Just want to know if it will do the job.

Hey skydragoness, all vlsd's are the same inside. If you want something better but don't want to spend the big bucks, try to score yourself an S15 HLSD.

Oh and for everyone here trying to figure out the different uses for the different diffs, 2-way is not just for drifting. Race teams will select different diffs depending on the track conditions. They may even use a fully locked diff.

Er, yes all vlsd's are the same inside, but the gearing is different in the s13's vlsd vs the j30 and some others. I'm just going off what i read from some people who have said lsds installed on their cars.

A fully locked up diff will not benefit a road racing car in any situation.

However a high lock-up ratio could...

Locking differentials are only used for off road and drag racing. The effect of a locked differential on the inner tire would destroy the cars ability to remain consistant lap after lap.

Christine a factory VLSD would work well in auto-x.

WoOT! *dances around*Even the so-called poopy s13 viscous unit? I really hope it does well, my bf's z32 pwned my car in the snow!

Here's a quote from an editorial about the JGTC skyline (the current Motul/Nismo car):The Hewland (tansaxle) transfers power to the rear axles via a locked differential at most tracks. The locked differential can be substituted for a conventional clutch-type limited slip depending on track configuration...
