arrg welding diffs is dangerous
if the weld isnt good it could break up and lock the rear wheels solidly
not fun on the motorway!
ok for track

also turns into a nightmare trying to park as the wheels try and turn at the same time ruining your tyres
and leaving black marks anywhere you use regularly

go for an lsd as its the best of both world, locks up with sharp acceleration and open when
driving normally

also you can use shims to tighten up the sensitivity

Search "LSD shim skyline"


also welding diffs is for cheap crappy cars where LSD's are too expensive in relation to the cost of the car!
ie E36 beemers, mk1 MX5's, Volvo 340's
This all confuses me lol I've had cars with welded diffs including a daily drive and never had an issue :)

So it's not safe on a skyline but it is on a e36/mx-5?

Most of the drifters I know have welders and don't have an issue. They are easy to park so I don't understand what your on about there?

Everyone has an opinion and I usually let people get on with it. But I disagree with everything you've put there bud. No offence tho.

Stu 92 - if your worried talk to Adams he has a R33 and uses it in BDC. It's got a welded diff and he drives it all over the country to drift no worries :)

Sure if its done badly then its not safe but if you fit a wheel badly its not safe!!! Lol if you don't chew properly eating your Sunday roast its dangerous lol

Ill elaborate lol
welding an "open" diff consists of welding the spider gears on the diff
so instead of letting both wheels move independently they are fixed and rotate together
permanently
(hence wheels skipping when turning as one wheel wants to travel faster than the other)

if the weld comes apart and locks the propellor shaft it will stall the engine
possibly twist it along with the subframe and the rear wheels will be jammed

is that much fun on the motorway? or 40mph a road with other cars about and trees etc.?
on a track it doesnt matter because your not going to kill anyone haha!
Ok thats the safety bit on ANY car;

The skyline bit is -
How expensive would it be to replace and fix these things on a skyline?
Compare that with the cost of an lsd and some £0.20p shims!

an e36 or mx5 etc. costs about £300 to buy all out, so if you trash it you can scrap it for
£200!
Or spend more than the car is worth on a decent LSD

In LSD there is an inner sort of clutch which temporarily locks the diff when
under pressure or strain and opens up when you let go of the accelerator etc.
so all in all a better way of doing things

and thats without mentioning the strain it must take from the extra power these rb25's put out, even if the weld is good it will deteriorate

each to their own just explaining
Ive had a welded diff on road before too lol
just putting the info out there

it is more expensive to do so hence why welding is more popular for track use
but would you weld the diff of an r35 GTR? or ferrari enzo? lol!

I see what you mean. And sorry adam didnt see you ask what its exactly had done to it, currently:
-Grounded first stage boost (earlier full boost)
-Slightly uprated intake (hopefully have uprated mushroom filter by firsy dwyb)
- Will hopefully have bigger intercooler by first dwyb
- Stripped out as only going to be tracked and a good service

Never having owned an LSD or welded i cant really input here =/ lol,
but I will probably go welded as had a go before in an r33 4 door at pod with a welded diff and didnt have trouble getting sideays/mechanical issues and was 4 of us nailing the hsit out of it all day in the dry.
Also Im only going to track it for the now so if i do get it on the road I will think more about an LSD or shimming another it when the time comes, but as its just track, like you said its hard ot kill someone lol

So just to confirm I can just get the standard diff welded for an R33 GTST?

Sounds good mate. Personally if it drives fine with the side mount I'd leave that on :) a front mount won't be cheap and the money's better spent on coilovers :) plus its harder to remove a smic on a wall lol


To WRLondon - it's a drift car not a track car bud. R35s don't have a welded diff because they aren't drift cars.

You might not like the fact that the wheels are locked but that's the whole point bud :)

Yeah wheels locked is great
by jammed i mean they wont move at all, cant move or drive the car if the weld breaks
and by track car i mean not on the road
It gives great consistency for drifting on track as its predictable
its just not a good idea on the road as a daily driver

Just have a good think about how the cars work
look up how diffs work and make a decision
not based on the cheapest way :)

It just frustrating on road as it can kill, **** your engine gearbox subframe prop
Let alone the extra stress on driveshafts etc

friebd of mine had a 200sx s14 diff welded up by a well known welder who welds suspension bridges for a living, 1 year later the weld broke locking the wheels at 75mph
spun 3 times hitting 2 cars and the barrier,
It had twisted the prop, tore the diff out of the mountings and scrapped the crank
car was a cat b write off
insurance never paid out due to the "dangerous" modification
got 9 points and had to pay for the damage
cost over £8k excluding the cost of his car and insurance rise

take the risk roll the dice :)
But hey as i said ive run a car with a welder before and they are fun

I find the last bit sort of weakens the argument but I hear what your saying.

It's a risk sure - but I bought a car last year where the braided brake lines weren't tied to anything and had nearly rubbed through... I could have had a huge and fatal accident due to a "fatal modification" and it would have been due to a "normal" mod if your with me? just installed by someone who didn't care if the driver and passenegrs died or not.

now I don't want to distract from your friend or the gent who welded the diff but... I know allot (and i dont mean 4 or 5 people) I mean half my facebook including at least 15 guys local to me who I know well, who run welders day in and day out.

your story is not only the first i've herd about this sort of thing happening - it's also the first time i've even know someone suggest the idea.

I don't want to distract from the tragedy your friend experianced but my advice to anybody getting into drifting is the same

weld you diff.... everyone else does

done

Keyboard warriors! Arghhhh
Welded, shimmed LSD blah blah
As your car is a gtst it is fitted with a v-LSD which is viscous limited slip differential, you can drift on this but it won't be great and if its quite tired you might get pee'd off with it not spinning up properly.
Give conceptua a ring and buy some shims- less than £15. Fit them in your diff and ta dah one awsome diff that has no dangers of killing people, cheaper than welding and awsome for skids.
I shimmed my standard diff and have been drifting on it for over a year with 550hp and 245 18" tyres it's still locks awsome!

As for rims take 16" standard alloys, if its dry or your struggling to kick the back end out increase your tyre pressure to anything up to 40-45psi if you don't have enough grip drop them down, in the wet I often run 22psi on the front and 20psi on the rear :)

Cheers for the feedabck, il set upa fund for coilovers then instead lol, any good suggestions?:)

Thats sounds, good to hear some experiences/opinions with different diffs. Im going to look into diffs a bit more as im pretty much a noob at the moment.

I tend to have it for a while so hopefully can try a few different diffs and see which is best suited. Only reason I am leaning toward welded is because like i said thats what I drove at pod before and was sideways in the blazing sun (R33 - RB25DET), plus the bloke said it was completely standard apart from the diff (welded).

As cooper says it takes less to shim your diff and that way its still good for road use etc. over here police have mobile mot units. All the young lads out in bmw's sierras etc get pulled in and diff checked. If its welded shes a goner. Unroad worthy vehicle. Your told to lift your stuff out of car and shes gone.

The fact that he said he's gonna sort out a recovery truck to get to an event suggests the car is off the road so welded diff should be fine!! I agree with the above though, shimmed diff might be better if your planning to put the car back on the road in the future. Where about in Birmingham are you based? Selly oak was it? There is/was a gearbox specialist in Ballsall Heath. SY Motors I think it is. Might be worth giving them a ring to see if they can weld/shim your diff.

Yeah cheers dave was just about to say I was using a recovery truck. But yeah i can see what you mean by getting pulled/inspected and no doubt your car will be taken! but like i said when it comes to getting it on the road i'll source another diff.
Il look at that dave see if if its still open, could do with getting it done properly, wouldnt want to risk it doing it myself... especially if ive got to turn back and head home after 10 minutes seat time lol
