where to buy bm or other "decent" lsd insert?

[cutty2fast]

i have been searching and searching and maybe i am just tired but i cant seem to find anything but phantom grip and like 2 no-name lsd inserts on ebay i've heard decent things about the bmt lsd insert but i cannot find a link to purchase one???? also my tranny is a 95...

Here is a link to a quaife lsd. Thery arent cheap though.

The Quaife Automatic Torque Biasing Differentials

i'm not really looking for the full lsd quite yet im eventually gonna go with a shep stage 2 trans with the wavetrac lsd but for now i have to pull my tranny to stick a clutch in there and i was gonna throw in a lsd insert

 

[WORPeclipse]

Oh ok i see what your sayin.

Pretty much all inserts are the same. You can try this one, it's not too terribly expensive but you still have to be careful with it: EXTREME PSI : Your #1 Source for In Stock Performance Parts - Extreme PSI LSD : Mitsubishi Eclipse 95-99 FWD

As with all inserts, they do nothing to fully control wheel hop - only spinning. With excessive wheel hop, the insert can cause catastrophic diff failure. They seem to be hit and miss.

 

[cutty2fast]

im not gettin any wheelhop just tons of spinning im really just interested in testing one out cause the tranny im pulling out of the car is going to eventually get a shep stage 2 rebuild and i traded like 50 dollars worth of stuff for this current tranny so im throwing it in with a cheap stage 4 xtd clutch

I wonder how that is a lsd. I know in the 4x4 sceen you can get one like that and it turns it into fully locked. We call them a mini spool. How does that work as a lsd can anyone explain?

It works like any other spring type LSD, just with massive spring pressure and no actual friction material.

OP save your money and buy the one from TRE. It's not so rediculously overpriced.

$85 for a ripgrip insert, or send in a core and get a whole differential with the ripgrip installed (professionaly) for $125.

Hey, anyone have any updated sources for these LSD inserts (automotive or otherwise kiddin Hehe hoho haha)? The extreme psi one still exists but not the other. Just want to see as many as possible before I choose one. Actually would like to find one of the "BMT" ones I've read about in here

Edit: found this one but haven't read anything on this brand

I'm interested in one of those too I was thinking going with ghost grip never heard of BMT and the one from extreme psi is identical with the one from GG. And one stupid question what is wheel hop sorry but English is not my main language.

Just keep in mind, these things fill the transmission with powdered steel. Wheel hop is when the wheel starts bouncing during a burnout.

What about this powdered steel business? What's "powdered" steel and what are the implications of having that in your differential? I've read really good things about these if they've got the upgraded springs

All forms of "phantom grip" inserts have a tendency to grind away little bits of the side-gears as well as simply wear away. If you never steer, then you'll be fine. If, after a drag run, you have to turn around and drive back up the slip-lane ... or if you drive the car on the street ... you will end up with powdered steel in your transmission.

These things are a cross between using a band-aid for a sucking chest wound and giving a patient with mild migraines a frontal lobotomy. I, personally, would not put one in my car. There's a guy from Texas with a GST with GSX brakes and mis-matching and ill-fitting wheels that I would love to hand a phantom grip to, but no-one else. Not even Snowy or Leon (who have never been seen in the same place at the same time, I might add).

There's a reason why "bm" is a great label for the latest version.

Thanks thanks and thanks but still waiting for the end of your point on bm unless it was already implied, but I didn't get it

 

[jtmcinder]

Ask any parent what it means when the family doctor asks about their child's BMs.

Oh, wait. I'm a parent. Ask me! Ask me! [waves hand in air wildly]

Thanks!

A "BM" is a bowel movement.

 

[Colt4G63 also]

Just to clarify, powdered steel is a type of finely ground up metal. Particularly steel.

Colt and I will be here all week. Try the veal.

That's Mike Huml's new company. From my understanding, Slowboy Racing was a bit up the creek without a paddle, so he moved the business to Florida, changed the name and has been trying to fly under the radar with the new name ever since. I'd probably steer clear at least until hell freezes over.

Jtoby, pass the A1.

So let me get this straight, this thing won't increase your horse power but WILL make your car faster? Hmm, what else can I upgrade? Clutch? That's a bit expensive though for the gains no? Tires too I guess then. I think i'm just typing out loud now.

 

[tkelly27]

You can use the spring from a Ford clutch type differential. It will do basically the same thing as the phantom grip or BM insert. I've not seen a transmission they have ruined, but I've also not put one into my cars for fear of ruining the transmission.

 

[juntjoo]

Yeah, I doubt I'd go digging in a junk yard for a part that deep in an old ford
Hey, what's in between one of these $200 inserts and the $1k quaifes? Is there a cheaper lsd out there or one for another vehicle that would fit ours?

 

[jtmcinder]

Start searching for a 1-way front diff from Cusco or Kaaz, and research whether/which front diffs from older Evos will fit. Also, I have no clue if you want this for road-racing, autocross, rallycross/gravel, or drag, so I don't know what type of diff your really want.

Thanks. I don't race but I may race myself or show off for someone, in which cases and just in general I would like better traction/responsiveness.

You can order the springs brand new from Ford for $7.00. If I'm getting anything differential related from a Ford in the yard it's going to be a solid 8.8 after my 3 bolt breaks.

These (and the spring) basically put pressure on the spider gears so there is some static friction keeping the tires spinning together.

A true clutch type differential (I think the Cusco and the Kaaz are both clutch types) will have clutch packs on the spider gears. The device inside the diff will apply more pressure to the clutch packs of the gripping wheel and less to the slipping wheel to keep them turning equally.

A gear type (Quaife) uses a set of gears. When one wheel spins faster than the other by a significant amount it drives the gears into each other and forces both wheels to spin at the same speed. I'm not super clear on how this works, but there are videos you can watch.

A viscous differential has viscous fluid on each gear. When one is being driven faster than the other the fluid becomes more viscous and that begins to drive the other gear.

A locked differential or a welded differential has the gears locked in place so they can not turn different speeds. This would be a pain on the front diff, so I wouldn't even consider it.

Which one is best? I'm told that the clutch type is the only one that can truly lock up and release. The gear types will only give you torque biasing, again, I don't know a whole lot about it.


You'll be a lot better off learning how to get your weight distribution 50/50 left to right with you in the car at race weight. Also, a good alignment for FWD traction helps a lot too. When you launch your wheels will become fully unloaded, if your alignment isn't set up for this you'll get a bad camber angle and not present the fullest contact patch of the tire to the road. Finally, good suspension pieces will make the car much more enjoyable all around, and a lot better to launch. The less it squats down when taking off the more weight you can have over the front tires for traction. You can think of it this way, if there were super light springs and no shocks in the back, and super heavy springs in the front, the front would want to fly up in the air every time you took off. This probably doesn't need to be said, but FWD's can't take off if they are trying to do a wheelie.

When you're at the reasonable limits of those, begin to consider your limited slip options. The only real choices are in the $1k range. Inserts don't really work all that well.

That visual is hurting my head. I'm even trying to imagine myself lying face down at the level of the frame of the car with arms from that jax character I think his name was from mortal combat 3 powering the wheels and i'm not feeling this inclination to go upwards. So then I re-imagined myself sitting indian style in the engine bay powering the wheels in the same manner as the last example and severed the car from behind the firewall and then I realized I forgot to engineer me a seat so I did so and attached a shipping cart wheel to the back of it so I can just take off while lying down. Still no feeling like I want to go upwards. hmm... What am I missing?

Either way, thanks for all that info for me to consider. And were you suggesting softer springs or something? And which ford transmission are we talking about?
