Locked Diff Vs. LSD

[wpayne]

Alright, I was just reading in a magazine that said a locked diff is a much cheaper way to go. You save more money. I was just wondering what the downside of the locked diff is.

[Replicant_S14]

A locker will "lock" the two rear axels together so that the wheels turn equally all the time. It might be good if you drag some peice of crap that you don't care about but it'd be a shame to molest a 240 that way.

go locked diff if you drag a lot (domestics do it) but the daily drive on it..good bye tires. i have a 2 way LSD and love it. i would suggest that. it hurts tires, but not the same way as a locked.

vlsd is pretty good, my friend has it but it is a bit laggy on the drifting, noticable but still worth the money. dont count it out.

Ok, so the reason why we don't have locked diffs stock is because of the tire wear?

I was looking at it more for a drifting application.

i dotn know about drifting. if it was good i think there would be more poeple in japan using it due to cost. but there must be a reason people go for 2 ways over this. cant dont know why.

but a locked diff will kill tires so fast. hehe...

IIRC, ae86 uses a solid axl...same effect.  Thats one of the reasons ppl like them for drifting so much.

A locked diff makes for massive understeer if you corner without being under throttle.

It also makes parallel parking (and other tight manuevers) a real bitch.

For a street car you'll be much happier with an LSD.

Ahh. I see now. I used to live in Japan and once in a while I would come across a car with a locked diff. I guess it's the cheap drifter's way of solving the open diff problem.

AE86 does NOT use a "solid axle".

true. &nbsp;the axle housing is solid but there are 2 separate axle shafts inside the axle housing that connect to the differential inside the pumpkin. &nbsp;this just changes the way the suspension is setup. &nbsp;

i had to replace a rear end on my .. crashed ae86. &nbsp;i bought the car for $500 before i had my 240 for the sole reason of drifting. &nbsp;i only hit a curb once, which snapped a rotor in half. &nbsp;3 days and $110+$4 [axle and gear lube] later, i had a new lsd rear end in. &nbsp;i didn't bother to connect the rear brakes and one night while grip driving in this one way street system with lots of tight blind corners, i came up to a corner at 80, locked up the brakes on pavement wet from sprinklers and hit the guardrail at 35[?] &nbsp;i i lost a headlight, hood, powersteering, a mirror, and the A pillar was horribly dented. &nbsp;i figured this would be my last night driving it, so i stuck my head out the window and did a few final drifts before i took an extremely back way to my house and parted it out.

Right. &nbsp;But that doesn't matter anyway.

The whole point of a DIFFERENTIAL is that the wheels, when turning, spin at DIFFERENT speeds. &nbsp;Just think about how much more the outside tire has to spin to turn in a circle than the inside. &nbsp;A locked (welded) diff does not allow this to happen. &nbsp;You have both wheels turning the same speed all the time. &nbsp;So, now when you turn in a circle, the inside tire will be scrubbing (squealing) the whole time. &nbsp;And turning will be a biatch.

Does that make sense?

The AE86 has a differential. &nbsp;All cars do. &nbsp;No matter if they are solid axle, swing arm, independent, multi-link, etc.
