?'s about welded diffs.

[Dustin240]

With a welded diff- Can you corner just as hard W/out sliding?

How many miles do you tires last? Please list hard or soft tires.

[WDRacing]

I wouldn't do it to a daily driver. A friend did it to his 180 in Japan and his car screeched and rattled on any turn with more then a slight degree. Grab an LSD from the junkyard. WHat type of driving are you looking to do? Drag?

it only screeches on tight turns. my friends welded diff never rattled.. dont know what your talking about there.

[nismofly]

to answer your first question...no you wont be able to corner as hard...youd need an lsd...specifically a helical

[WDRacing]

The rattle was crap in the car, the screech and pop is from the tires turning at the same time. No way I'm doing it in a street car. They aren't that much better then a good LSD anyway so why bother. I hook up pretty well on a stock VLSD.

I have a welded in my s13, and I used it on the street for about 6 months.. I felt it was a lot more predictable, especially compared to a vlsd, and much more fun. It only screeches on smooth streets if you're going less than 10mph.. Also, my tires lastest a hell of a lot longer than I thought they would... Welding your diff isn't something you do just because, there needs to be reason.. drag racing, drifting, or such.. not just becuse it sounds cool. Trust me, you get tons of traction in a straight line, and can get the car to stay sideways a long time if you're into drifting...

here's what about 130whp KA does with a welded diff and BFGoodrich tires, they're pretty sticky, and only had 800 miles on them.http://www.youtube.com/watch?v=AELJkDwoVh8

I have a welded diff in my S14 w/ KA-T. I can take corners just as fast, if not faster, then with an open or VLSD. I hate when people talk **** about a welded diff and have never owned one. It's very streetable and daily driveable. It acts exactlly as a 2way in most conditions. Don't get me wrong, there's no replacement for quality clutch type LSD. But a welded is a good 'good for now' alternative.

[KATwo40]

How would you say it does in terms of rain driving, when compared to the stock open diff? Obviously, it might break out more easily, but is it more predictable?

I'm asking because my wife drives my 240 every day to and from work, until we get her a "my husband can't touch this one because I won't let him" car. I have been seriously considering welding the diff, but that's the main holdback for me. I couldn't begin to put her in a car with a high risk of spinout.

Thanks!

[solaris22]

It's very predictable. But in the rain you have to drive conservatively. Honestly I wouldn't let a wife/gf drive it in the rain. Women are horrible drivers as it is

[lrb_2000]

Exactly. I have no problems driving in the rain, or any weather situations with it. But i'd never let anyone else drive my car. It's something you need to go out and get used to after you install it. At high speeds, it's very stable, and easy to control... $50 > $800

Also, in such a light car, it's very hard to acually break one if welded correctly.. you'd have to be putting down some serious power, and running some slicks or such.. but if you're putting down that much power, i'm sure you can afford a LSD.

[Chezedik]

There is no way that you will turn as well as stock, since it is the job of the differential to create a (get this) differential in speed between the wheels around a turn.

[solaris22]

You're saying an open diff can take a corner faster than an welded diff?

[KATwo40]

You're saying an open diff can take a corner faster than an welded diff?

I'm gonna go with Chez on this one. The differential (LSD or open) is designed to allow the inside wheel to spin more slowly than the outside wheel, keeping the car from being pushed toward the outside of the turn.

A locked or welded differential has but no other alternative than to cause the car to push and have more potential for oversteer.

I think the issue is not so much maintaining a certain speed through the turn as it is maintaining the desired line. Which, obviously, results in faster track times, even if the cornering speed is lower.

I think I'll hold out for either the OBX helical unit or a J30 VLSD.

Thanks everyone for your input, especially those with experience.

[Chezedik]

That is exactly what I am saying. But the problem would be one with understeer not of oversteer. Basically, the car will go straight when you want to turn, it will drag the back wheels around any turn it makes and will def slow down lap times. Do a search for 'Detroit Locker', you will get better insight. The prinicipal is called Ackerman's Principle. It requires that one wheel spin slower in order to make a turn. If this cannot be done, then the back wheels will chirp around turns as at least one has to break the limit of traction in order to turn. It is like a mini-burnout. This is only a worthwhile mod for a drag car, and while drags are fun, the 240 is no drag car. If you wanted that you would have got a Camaro or a Civic. Get yourself a good LSD, and you will be much happier. Also, have you thought about what happens when that weld finally breaks (if it does)? KA-BOOOM!!! In snow and rain, your rear end control will be next to non-existant. This mod is just unsafe, non-benefitial, and something else to complete a series of three. If you are looking for a cheaper way out, get a Phantom Grip. They work, but make sure you have enough power to break the wheels lose or you may break some parts.

[WDRacing]

Wait a minute Chez, are you trying to tell me this isn't the best mod ever? Are you sure you know what you're talking about? You may wanna do some more research...lol.

[Chezedik]

I am sorry, I did it on my Honda and it took 3 sec off the 1/4, plus then I could make my Civic drift.

[Dustin240]

3 sec< Sorry I call BS on that one. Are you runing crazzzy horse power or you just dont know how to launch.

[KATwo40]

Sorry, I meant understeer, not oversteer. Thanks.

[solaris22]

So with that logic a 2way LSD would also corner worse then a VLSD or an open diff. The welded acts very similar to a 2way in cornering, the difference being a 2way provides less lock when decelerating.

I'm not going to type out a long reply, do whatever you want. I stated earler theres no replacement for a quality clutch type unit. I've owned a 1.5way, 2way and welded. They all have their pros and cons.

2 ways arent good for handling either, neither are open or viscous

1.5 way are better, but if you really want handling your only option is a helical

[zero_gripS13]

not necessarily...

1.5 may be good for racing, but theres alot of varibles.. some high speed racer preffer and use a locked or "welded" rear end... other use 1 ways..

if u have a kaaz 2 way set to 100% lock force, then it will be locked the same as a welded when acceleraing and decelerating... the difference is when going slow and stuff then the lsd allows the insides tire to change as compared to the outside.. that is why u hear clunking and clicks and noises the diff is unlcoking and locking....in a welded this does not happen instead the inside tire skips chirps.... so yea...

900$constant fluid changesrebuilds

or

10-200$no rebuilds no maintenance...

i personally just picke up a weldloc differetial from luke at zilvia...

i use my car to drift ... it was the best choice i could have made ...

[KATwo40]

For drifting or drag racing, I wouldn't think twice about welding the diff.

But I also make hard Dragon runs, autoX the car, it gets daily driven, and I plan to do some track days at Road Atl, Roebling, Mid-Ohio, etc.

So, it's just not for me. But if it were a drag only...I'd weld that baby tight!

[lrb_2000]

Good call. I welded mine up because my VLSD sucked, and I will be Drag racing, and "drifting" or whatever more than anything else. Plus it's not my daily driver anymore.

[Florida240sx]

Anyone got pics of their welded diff?? My shop won't do it unless I give them a pic...... Any prepping needed??? Spray carb cleaner on it and dry??

[Chezedik]

You need to get it very clean if you want the welds to hold, so try brake cleaner.

[solaris22]

Here's mine, I pointed out the spots that are welded. It needs to be very clean. Also, it's best to use a high nickel rod when welding.
