Best LSD?

[FBI14]

What do you think would be the best LSD if someone were to swap out the stock one on the MSP

[ddogg777]

The only other one that I know of is the Quaife lsd...

[CHICO2003]

Am I the only one that thought he was talkin about the OTHER LSD?

[ddogg777]

How many lsds does the Mazdaspeed have? Yes, you are the only one...

[spacemonkey]

yup quaife is the only other company that I can think of that has LSDs for our cars. I wish Kaaz would come out with one.

[TurfBurn]

The quaife is the best quality performance wise, but is very expensive comparitively. There are supposedly two version of the MSP LSD according to some people on this board.... the original and the revised (clutch versus possibly posi-trac style).

There is also the phantom grip if you wanted... but that's certainly not any better!

[spacemonkey]

phantom grip i heard is horrible in turns...def quaife is best for performance but its really expensive. Thats why I like Kaaz...I heard good things from the 240 guys and its relatively cheap.

[Glowmunkey]

What type of LSD does Kaaz produce?

I've also heard about two different LSDs for the Speed, but was never told that it was a totally different design. I was lead to believe that it's the same basic diff, without the springs that allow it to 'sense' torque and function in a turn.

Phantom Grips don't suck any more than an open diff in a turn... they just don't help all that much. They'll help you put the power down coming out of the turn, and certainly in a straight line.

Quaife is expensive, but seemless, strong, and guaranteed for life. If my LSD or tranny ever blows, a Quaife will mostly likely find it's way into the Speed.

I mentioned phantom grip largely as a joke :) I just don't agree with slapping in two slabs of metal into a standard differential and believing that it will work well or for a long time!

I'm curious about the Kaaz stuff though!

Nope, I was going to say micro dot

perfect for weekend drag racer..

it makes it a lsd.. but remember that a lsd made to be a lsd is a stronger unit as in

example:

a stock diff hold 300hp.

Astock lsd diff hold 500hp

a stock diff with phantom grip still only holds 300hp.

but it works good for the price

From what I've seen a phantom grip basically is 2 plates with a spring in the middle, and 2 metal straps on the side. What your supposed to do is put it in between your spider gears and cut the strapping. From what I've heard they seem to work pretty good in a straight line. I really dont trust such a product...and such a cheap price.

I only mention Kaaz cuz its popular with the drifters and its fairly cheap.

[TurfBurn]

SOB, lost my last post..

My issue with the phantom grip is not that it does or doesn't work, but that wedging metal plates into an open diff is a bad idea. It will wear and load the diff in ways it wasn't designed to be loaded. I think it will cut the power from 300 to 200 for example... the diff wasn't meant to have that kind of pressure put on the spider gears and so forth, and thus is a bad idea. That's my thought on it, not that it doesn't work necessarily or do what they claim.

the best lsd is the one that you won't have to think about breaking and is really cheap.....when you find it let me know !!!

[jersey_emt]

LOL nope you definitely are not the only one

[TurfBurn]

It's called a welded MSP LSD, I have one :)

Ah, the '1-wheel burnout' LSD

[TurfBurn]

nope, I can thoroughly assure you that I lock both wheels very solid. Works fabulous and I can leave very nice even streaks. Works amazing during autocross to the point where I can drag the rear end into a four wheel drift. So certainly no one wheel action with it in any way shape or form in all my racing high speed (110+) and low speed (auto-x)

[terbow]

anyone have a quaife yet? where can we get one?

[Glowmunkey]

Haha, yeah... we all wish.

[TurfBurn]

Little Beavis has one. Who he got it from I don't know.

[vindication]

if I'm not mistaken the Quaiffe isn't a direct fit, right? There is some tweaking needed to be done but cant remember what.

[mspeed101]

Does anyone know how much the quaife lsd costs?

[Dimitrios]

The Quaife is available from www.mazdamotorsports.com. If you intend to buy something from there, you must show written proof of at least 2 racing events (auto-x, drag, etc).

[spacemonkey]

Does anyone know how much the quaife lsd costs?My guess ia a good $1300-$1500?

www.Mazdamotorsports.com (http://www.Mazdamotorsports.com) is good.. or you can try www.corksport.com (http://www.corksport.com)

[JDM Sam]

wesman has one. hes in the process of installing it with thicker axles.

There are 2 MSP LSDs:
old design with springs locks up better but weaker casing.
new design no springs. how the new one works no one knows for sure, supposedly stronger because the lack of springs to exert the amount of force to lock up the front wheels.

Like mentioned not many options maybe weld a locker spool in place and lose all turning driveability.

The only thing you have to do is shave down the top of the gating plate to allow room for the screws/nuts on the bottom of the quiafe from the ring gear to pass without hitting. Can be done in 5 minutes with a dremel and you are set to go.

[t3ase]

How many lsds does the Mazdaspeed have? Yes, you are the only one...
someone missed the jooooooke.

That answer could also depend on 'career' the driver has.

Okay to contribute, as everyone else has said.. There are (confirmed) two models of the MSP LSD; sprung and unsprung. It's available through ProtegeGarage for around $600, I think. There's also the Quaife. The quaife is available through CorkSport for around $1400.00.

I read somewhere that the LSD we have is a very economical unit that does the job but is extremely cheaply made to reduce maker's costs. That makes sense. However, the only known problems I've come across have been it splitting which TurfBurn corrected by rewelding. Most*** owners who have taken the car in for the LSD issue have had it replaced under warranty. If this happens, I'd STRONGLY advise you to then take your car to a tranny shop or a friends so you can weld that mofo on. If you don't, there's no tellin when it'll pop again if you get the old model. It's worth the downtime now to prevent a huge downtime later.

Good luck
