I want to do an event very soon and do not think i'll have time to get a real diff. The only thing i have handy is an stock S4 t2 clutch diff. How bad will this be ? My only experience is in my old car but that was drag racing... Just trying to see if i will be wasting my time swapping the torsen

 

Been drifting stock diff for the last 3 years.

Sure, a after market would be nice but not absolutely needed.

 

i was concerned about it not locking up fully while drifting, these diffs are pretty non-aggressive

 

S4 TII diffs are the ****. Many people abuse them, run 10s and ect at the strip and they can last a good amount. It will be fine for more than one event unless you have bad luck or a **** diff.

 

i guess i'm gonna ask. has anyone tried both ? on the same car ? S4 vs Kaaz etc ?

 

my car is stock S4 TII rear diff, and it does this. super worn out but throws down still.

im either going to weld it, or invest in a good diff. we'll see after sema.





my best advice is just to run it, and find out. drifting is about getting by with as little money spent as possible... at first. then get nutz!!!

 

i have a s4 t2 diff that forrest welded... its coo.

 

hey is it still holding up?
do you clutch ride **** alot, and upshift hard/do 2nd gear linelocks?

i was going to give him mine after nationals to weld. i just dont want to break it, cause then i HAVE to spend a grip on a baller diff...

 

Shim, shim, shim.

If you want aggressive, that's how you do it. Shim that bitch.

Weld it if you want. It doesn't push bad unless you're going like 0-10 mph GRIPPING without being somewhat manly with the clutch/throttle. I've been daily driving on a welded for two weeks now. I dont notice **** unless i'm parking or taking a low speed corner. The chirp/chatter **** is rather annoying but whatever. Gotta sacrifice **** to play hard.


If i can afford it, i'm throwing a kaaz 1.5 way in my s4 TII pumpkin next year.

 

does your diff shake, and bang **** when your making low speed turns... i cant stand my car feeling all shitty like that.... 13's are cool, cause they dont do it bad, but FCs have weak *** mounts, and ***** always whored out.

 

dude full throttle 2nd some 3rd with 275's and 285's and it holds up great...

doesnt feel like a shitty welded NA diff though... wayy different than what NoPistons has to say.
pretty smooth and not chattery cuz the 275's dont break at when not dorifto


Cj ( the full race fabricator that lives at erics) was saying that they would gutt the clutch assembly and weld the remaining, but doesnt look like they did.

 

hahaha cj gave you the juke!

 

its Ben right??? not eric...

the dude that has the huge mansion

 

Any more detailed info on shiming the stock diff? I had a shop rebuild mine and they fucked it up. The pass side will spin cruizing @ 50 if I roll on the throttle , and the dirver side won't lock up EVER.

I picked up a diff from a 10ae that I was gonna swap in, but I figured I should freshen it up if I'm goin through all the trouble. Ideally I'd like to get 20-25% more aggressive lockup, but what does that equate to in shim size?

Also has anyone rebuilt a T2 diff using those thicker clutch plates from mazdatrix? does that yeild a more aggressive lockup or just increased wear resistance?

 

i welded the s4 t2 diff in my gold car.
gutted the internals, welded the stub axle housings to the casing of the diff.

 

Use the first cone washer in the stack as a template and make a shim out of a flattened red bull can, If you need thicker use a regular pop can. Put the shim between the case and the cone washer. A single shim will typically turn a worn (<10ft/lbs of breakaway) into 50-60 ft/lbs of breakaway(70-75 ft/lbs with a pop can). Two red bull shims will put you into 120ft/lbs + territory.

i think you guys have convinced me. i'm gonna try it out. since i have one already... although the cusco diff would be awesome

 

So you have fully locked wheels all the time and you're not having ANY chatter or chirp? Sounds bullshit to me because that's the NATURE and BEHAVIOR of a spooled diff. One wheel is going to slip on the pavement and the other is gonna grip. If anything, you're lifting one of your wheels OFF the ground hence no noise.

That's how it works. Circles and physics.

LSD is completely different. I had ZERO chatter or clunk from my real lsd.


I did a write-up with pics but someone was misusing and screwing around with my photobucket so i deleted them. Didn't have saved on this computer and the old computer was wiped due to viruses. No firewall is safe from koreans that play starcraft.....

Just throw shims on parts that dont move. I used pbr cans for the sheer trashyness of it. Someone on here can attest the **** works besides myself. I just couldn't drive well enough to make full use of it.

 

physics shmiziks...

as long as your diff isnt open, then just get out to the track and drive. tear it up with the cusco or the stock clutch type.

the moral of the story is to go out and drive... put in work

 

lol yea its ben, but its hardly a mansion. CJ flew the coupe after like right around forrests birthday.. hes back in AZ working with Full-Race again i think he said.

lol Ben's house is a normal 2 story house.... thats average for out here. mansions here are like 3 story ******* white houses way out in northh town, by the mountains.

dudes live on man made lakes and **** looking all rich.

 

I have the cusco. Its nice to have and gives me options as far as what the car can do. i.e. auto-x, time attack, hpde.

 

Yeah. Weldeds are fun, dont get me wrong. You just have to learn how to drive.

No heel toe and doing brutal engine braking downshifts in the rain intending to grip drive=no good. You might be able to get away with it running an open or lsd but with a welded....any steering input or weight transfer during this WILL PWN YOUR *** if you dont know how to drive.
