So i found a couple good write ups on shimming a vlsd, and i definatley want to do this before i put my vlsd in. The only thing im curious about is that supposidly it shortens the life of your diff itself, which would make sense. But i cant really find any info on how fast it wears it down

so i was just wondering if anybody has been running a shimmed vlsd on their car and how they like it and how well its been holding up over time and abuse

and incase anyones wondering

when i was at a track event here there was a guy who had shimmed his diff to a 2 way and i believe he had it for 1.5 - 2 years like that and it wasnt giving him any problems yet

2 way = always locked, same as a welded if you ever driven with a welded

1.5 way (1 shim) sorta like a vlsd, full lock on load, not locked off load (i think)

you can also change the aggressiveness of the lock depending on the thickness of shim you use as well.

a 2 way locks under acceleration and deceleration (off throttle), where a 1.5way locks under acceleration, but only partially on deceleration

as far as a 2 way being the same as a welded, i dont think a 2 way is as 100% locked like a welded, otherwise there would be no point of it

lol well the gearing in aftermarket 2 ways are usually better and safer to run than a welded stock gearing

possible its not 100% locked and that would change the feeling durring a drift for sure, but not locking 100% means you dont get that 100% predictable feeling like you get with a welded so i guess it would be a prefference/gearing/reliability choice

1.5 when shimming can change the load it takes to lock it under both acel and decel by changing the thickness there is like 4 shim widths that can be run and with the possibility of running 1 or 2 or 3 shims it can be dialed in pretty close to whatever you want it to be im sure

You're quite possibly the most ignorant person on this forum.
1) 2 Ways are NOT always locked. They lock 100% under hard acceleration, and lock 100% under hard deceleration. Anything else and they're open. Therefore ideal for daily driving. But most of this half-assed forum can't afford one.
2) 1.5 Ways lock 100% under hard acceleration and lock 50% under hard deceleration. Hense where the ".5" came from.

Shimming a viscous DOES NOT, I REPEAT DOES NOT make it act like ANY sort of clutch-type differential. Yeah, it might lock harder, but it'll NEVER, EVER lock as hard as a 2 way/1.5way/welded. You're a fool if you thing anything differently.

The fact will ALWAYS remain that viscous' SUCK ***hole for drifting. That's why most associations won't even allow them for drifting (IE Club Loose). They heat up and become useless.

Hell, you can weld your diff for less than you can get a stupid f*** viscous.

People need to educate themselves on this s***; for real. :facepalm:

getting hyper-butt hurt over here

i was trying to make the comparison when drifting of the 2-way being like a welded as it being 100% locked (acel/decel) not litterally all the time! i guess i didnt convey my meaning good enough

when i was reffereing to the 100% lock i mean durring load, 0% being its not locked i.e. open (one wheel spins the other does not), 50% being its failing at locking 75% being its mostly locked so on and so forth until 100% being its fully locked...UNDER LOAD!! not 100% of the time as in there is no load and its locked

and the "(i think)" after the 1.5 way means i dont know for sure, once again, not claiming i all knowing like yourself, were all here to learn, otherwise why the f*** would we be on a forum asking quesiton and researching, got off your high horse

as far as your ranting about the vlsd, i trust you've driven a car with a shimed vlsd in order to make the comparison between the two. not everybody is super die hard about there diffs, if the "2-way like vlsd" shim locks hard and is predictable and they like it they like it...dosnt make it inferior to another diff just because they faking the funk.

you set up the car how you like it, if you like the feeling you keep it if you dont you change it...the shimmed vlsd gets alot of good reviews so you shouldnt knock it for not being a clutch

when i shimmed mine i didnt use 2 shims, just 1, the thickest one they have. according to what ive found it should make it behave closer to a 1.5 way but we'll see. i havent tried it with the shim yet but i used my regular vlsd out of a 180sx for a few years and i like it

jesus christ lol somebody was having a bad day

I really want to try this, im just not sure if i wanna replace the one i have now with a thicker one, or just add a slim one to it

heres some more input on this question, the same thread but on a local drifting forum
http://www.sfldrifters.com/forums/showt ... hp?t=63637

as you can see some people are bashing the idea, but those are the people who bown down to the welded diff and think that ppl who would rather not have a fully locked diff for a daily driving and would also like to do other motor sports besides drifting are vaginas.

also, if anybody here has put vlsd guts in an open diff hosuing, could you help me out here? A few questions reguarding the half shafts not being the same

Anyone?

And according to one person
This shim that your adding is for adjusting the VLSD, not for making it lock. I read this write up, then tried with with double the factory shim. Then tried it with a barely over sized shim.

They did not make the diff lock harder, because it is THE FLUID INSIDE THE DIFF that makes it lock. Not that shim. All it made it do, is get hot super fast which makes it stop working until it cools.

then like 3 weeks later, they decided to blow out the side of the case. $100 diff + $10 in fluid + $10 shim = $120, welding an open $50.
Now im a bit lost cause on the write up thread people say they lock amazing and its the best thing ever, and no problems, then two ppl on my local drift forum are saying that it sucks and the diff just blows out after a few weeks and its not worth all the hastle.

Im not getting a 1.5 way cause one there expensive, two i daily my car and i dont want to deal with that clunking. Same with a welded, yes its cheap and awesome for drifting, but its annoying as hell to daily, and it sucks a** for any other motorsport thats not drifting. Vlsds are good for the street, and making sharp fun turns, but they arent the best for drifting and everyone knows why

so im trying to find a happy medium here, which i thought would be shimming, but apparently that doesnt even work that well according to some people
