Just curious (as the subject says) how many people are running welded diffs? I've been running mine for about a year no problems.

Re: How many Welded diff's???
Ran one for about a year. It was street driven, and chattered alll the time. I ended up having it give up on me locally (luckily), and limped it home. Put in a lsd, and went for a cruise, had my buddy who had rode in the car a thousand times, came to a corner and he started clenching the seat like it was going to slide, nice smooth lsd. But now I run a lsd and think how many times before it lets loose....

Re: How many Welded diff's???
I have been running a welded diff for 5 years with 400+ WHP :nanan?re

Re: How many Welded diff's???
I might weld mine, if I get it running before the s13 subframe swap.

Re: How many Welded diff's???
The funny thing is my Z doesn't like to slide even with the welded diff, probly something about the tires, the alinement, or I just dont drive fast enough, idk… Wish I could afford a lsd sometime in the near future, I dont really mind it welded that much but parking can be a pain & I know a good lsd would be better all around.

Re: How many Welded diff's???
Mine is welded. Cheap, easy, and not nearly as bad as everyone made it out to be. Really glad I didn't drop a huge wad of cash on a "proper" diff.

Re: How many Welded diff's???
Yea, i agree with you. The welded diff has worked well for what i wanted it for. but down the road i want a nice lsd to make it that little bit nicer to drive around. But honestly everyone makes welded diffs out to be horrible uncontrollable beasts & that's really not the case. This is the first time i've welded one & its held up without any issues.

Re: How many Welded diff's???
You guys might hate me for asking but what is the difference between a welded and non-welded 1?

Re: How many Welded diff's???
Well.... a welded diff is welded. And a not welded diff is not.

Re: How many Welded diff's???
With a welded diff you take a open diff and weld the 4 spider gears in the carrier bearing together so they don't rotate and it locks both sides together. When you dump the clutch both wheel are throwing smoke instead one, which occasionally happens with open diffs. I've been thinking about doing it to my truck if I don't get a locker first.

Re: How many Welded diff's???
The main goal of the welded diff is to make better sideways.
When you mash the gas exiting a corner with an open diff, usually only the inside wheel spins up and makes a bunch of smoke but you don't slide. With a welded diff both rear wheels are locked together, so for one wheel to lose traction the other wheel has to lose traction. So when you floor it mid corner either you accelerate down the road, or both wheels lose traction and you go sideways.

Re: How many Welded diff's???
Thanks for the explanation.
So what would the advantage of a welded diff be for a street driven car? I can see the advantage for someone who races or tracks their car but wouldnt having both rear wheels locked cause problems on the street? especially in incliment weather?

Re: How many Welded diff's???
Fuck a lsd.
Welded ftw.
sure you waste tires a little faster, but if you drive like an ass, it's inevitable
if you take your time and don't take turns at 40+mph then you'll be fine and as long as your alignment is okay you won't be scared in the rain
about to get another welded in there since I just blew mine (not from the welds) due to not shimming it correctly

Re: How many Welded diff's???
It also allows for more controlled straight line accel when traction is limited… I used to have this problem where one tire would spin in second + alittle fishtail which would cause weight to transfer & the opposite wheel to spin going back & forth. This would get violent @ cause violent regrip situations. I find the welded diff much more controllable in those situations. & you get used to drifting in the rain.... It becomes a fun thing on the side. Just wish i could make my exhaust so i didnt draw so much attention.

Misbehavior. :twisted:

Re: How many Welded diff's???
I've used welded in some other cars, but on a stock Z31 with tired bushings, I would imagine stuff back there would start falling apart in a hurry. They are really shitty at the limit when drifting, as it won't respond to throttle inputs as well to keep the car in check. This gets worse when you upgrade your wheels and tires and add grip.
Then you guys who think LSD's are a waste of cash start spinning out and make posts on FB about how the Z31 needs moar steering angle.
They are great for just starting to learn while burning up crap tires. To date, there are probably 8 people on this forum with REAL aftermarket LSD's in their cars who can tell you for sure if it's worth it or not.

Re: How many Welded diff's???
i had the stock diff in my 86 welded so i could drift. i dailyd my Z and gave drift lessons at U-DRIFT in vegas for a year and a half.
it made TONS of noise when cornering, completely unsafe in the rain with any kind of power. tires sqeal on concrete. girls ask if and assume the car is gonna fall apart.
the shittiest thing about welded is IF you get a flat tire and the spare is smaller than the other side…your gonna destroy the spare. i speak of this because it happend to me.
then i swapped in clsd from a 88t. never will i go back to welded. the lsd is quiet, smooth, (worth decent $ if i wanted to sale), tires last longer, you can take corners quick, more safe than welded in the rain, and the ability to lock both together when i want.
no control in a welded diff…but the one REALLY cool thing about welded is strait line stability.

Re: How many Welded diff's???
lol @ people who say weldeds make alot of noise..
my tires hardly ever squeal at low speeds, I have high cornering capabilities, and ultimate control even with slicks..
Just learn to drive a little more cautious and learn your car..
and I will never use a half-assed piece of shit donut spare tire as a spare period
those things are trash
plus my tires last quite some time. but I drive fast 99% of the time or drive like a jackass 99% of hte time

Re: How many Welded diff's???
im sure your car handles awesome on a track, especially when your on slicks and your putting your high cornering capabilities to the limit in your na 2+2! maybe ill make a special trip to see your skills. im in austin, i have family in clear lake, it will be a good chance to see them…and those capabilities.
it doesnt matter what tire you use as a spare, if it doesnt match the opposite sides tire height, youll tear it up.
welded diffs make and cause noise, if not, you must have not put many miles on it, or actually drifted much with it, because it WILL start making noise. your tires last quite some time? i went thru a pair every 6 months with a welded diff, went lsd and the same pair lasts a year. then again, im running 245s....not bicycle 215s on a 15 inch wheel.

Re: How many Welded diff's???
lol..
friend is running a VQ35 in a S14 on 255's, daily drives/drifts welded diffs day in day out.
another friend, drift car, ka-t 300+ whp welded diffs on 245's, those tires last them the whole event (federal ss 595)
man you people are arrogant and can't stand a little bit of chit chat
but wait I don't live in the old ages LOL
oh and Ian is running a welded as well.
And now I have my car boosted and 215's don't even hold traction
but i'm not upping the tires until I get a cage, new clutch, and start competing.
I love how people are such jackass's and can't respect someones opinions.

Re: How many Welded diff's???
so your saying that your friends have welded diffs, not you? your a joke. welded diffs making noise is not an opinion. its a fact. why were you sayin that shit about your superior handling capabilities and even better on slicks when you are running a stock clutch? retard. fool. dont say anything else on this thread. please.
