hi people, what diffs are good for road use and one that can actually spin 2 wheels instead of 1! as my std lsd sometimes lets me down.
i was thinking about quafe but aint really up on the different types and prices etc.
i drive the car almost every day so cant just be welded up etc.
anyone with some expieriance as to which one to go for would be appriciated.
iv herd of good yhings with BARA ??? anyone no anything

Spinning 2 wheels is going to be more down to grip and power/gearing, I was going to suggest welding it!!

I drove my Cossie daily with a welded diff, was fine to be honest. They really are no where near as bad as people say, the only time you really notice it is tight turns or parking. Makes it twice as fun and only goes out when you provoke it still.

You need a plated diff with appropriate ramp angles, and plate congfiguration

my mate is into the nissan drifty things, he has recently "shimmed" his viscous lsd, by putting a thicker spacer between the coupling and plates, effectivly increasing the pre load on the plates. TBH it behaves like a welded one, usual skittering when parking or making a tight turn. But he assures me you can get it in between with a thinner disc. He drives this car daily with no probs though. ill see if he has a post on sxoc about doing it.

here is the link, not sure if a sierra diff is the same but im sure something similar is posible.http:http://www.sxoc.com/vbb/showthread.p...ight=diff+shim

You can't shim a ford diff, it's different.
For drifting you needs a locker diff or a plated diff. Welded is the cheap option, I use one.

For a plated diff you need one with 45/45 ramp angles.

mig spec cheap reliable and just awesome compared to the sketchy standard ones and stronger due to losing the planet wheel failure that will happen if driven properly

umm decisons.... wot doud a welded diff drive like around the twistys at 70-100 mph mark as i go to wales often and i like to drive moderately. i dowanto upset the drive,

chaffe

i see, never had one appart mate, can you weld an lsd, or does it have to be a std diff to be able to weld it?

robrs2

Yes the planet gears can be welded on the lsd.

I would not like to use a welded diff everyday. Damp roads are not easy with a welder.

keldsyke

Hi, there are no planet gears on an LSD, why you would want to weld an LSD I don't know. As you say having 45/45 ramp angles will give lock up on accelerating and braking.

As you say, a welded diff is effectively dangerous

chaffe

effectivly dangerous or dangerously effective

I've had an LSD diff welded. A couple in fact.

They are no where near as dangerous as some people will make out; you hardly notice it in fact when normal driving.

ajamesc

just get a gripper locks up both wheels every time!

what about driving on track in a welded diff - surely it will step out a lot more and will eventually catch you out

welded diffs are great, there not dangerous only if you are kicking the clutch on a damp road will it go out.. if you buy a plated diff and set it up for drifting with the ramp angles you will find it will be near as bad as a welder when parking and tight turning..

you may as well just weld your own.. ive been on a welder for over a year now with no plans to change it..

chaffe

i think ill weld mine first for the cost of sweet FA, if it upsets me too much, or kills me ill consider changing it.

robrs2

Yes there are planet gears on most lsd's. The ford vlsd does have them. If the rear case is opened on one most people looking at it would think it's an open diff as all that is see in the centre are the planet gears.


I did not say dangerous. They are too unpredictable for road use. Yes you can use it but with caution.

On wet trackdays I find the welded diff a big pain in the ass. It's too hard to control over steer or under steer. But in the dry it's fine.

I drove a welded diff on my first ohc-turbo as an everyday car, and except from parking and tight turns it really isn't noticable. A bit more noise at motorway cruising tho.

BUT, when I drove it in the wintertime, it understeered massivly. Always had to tap the throttle to get the back out in turns, or else I would've ended up in a ditch

But you have to love the predictability when playing around
