i have pretty much given up hope for a quaife diff for our car and i heard from the spec-v guys that their lsd is nothing to write home about, which unfortunately leaves us with one option...phantom grip >:( well, i guess i've just heard things from people about phantom grip that i don't like. so here is your chance to make a beleiver out of me. if someone who has this mod and knows the pros and cons please tell me because i am sick and tired of no traction! and it only gets worse the more performance mods you do!

p.s.-does kaaz make an lsd for our car?

I have seen a kaaz lsd for our car int he past.. not sure where to find it anymore tho.. hrm i can check but if someone else knows post away.

www.real-engineering.com sells the kaaz for our cars and you should ask T.C. about the phantom grip, he uses it...

www.roadracemotorsports.com has a kaaz lsd

Phantom grip works great. Wheel hop is cut down to almost nothing and launches are much better. For the price it is an excellent upgrade. By the way, key performance sells tha Kaaz limited slip also. I don't think the phantom grip is as good as an actual full limited slip differential, but it mimics that pretty well and is much cheaper. It is an easy install also. If you do go with the phantom grip I reccomend that you get the upgraded springs though. Not much more expensive but a lot more holding power.

If I was going to be doing a LSD, I want it done right the first time.

I love how everyone like how the phantom performs right now for the money. But most forget that eventually you will have to rip out the tranny and replace it (which is not cheap to do) again!

Is the Kaaz LSD similiar to the qualife in the way it performs (one wheel lifting up and all)?

Thoughts?

Qualife- your best if you can get it made!
Kaaz- not sure, need information
Phantom- great admission price and performance, needs to be replaced (more labor!)

Actually, according to Phantom Grip, If you have the upgraded springs the unit will hold well over 500hp with no problem. They even have some drag cars that use it. And no, of course it is nowhere near as good as anything Quaife makes. But then with quaife you are talking at least 4 to 5 times as expensive and in the case of the tiburon I don't think they are available. Regardless, phantom grip is plenty for almost everyone on this board. But everyone can do what they want. Your best bet of course is to find some local tibs that have one or the other and see if you notice a difference. Good luck

I, too, was interested in the Phantom Grip, so I emailed them awhile back for some more info on their product. Here's the email that they sent me:

We are working diligently to try to improve on the information of
Phantom Grip products. Our new site launches this fall to accomodate
both the performance and the oem marketplace.
Now as for hp/torque info.
hp ranges have been seen from stock to as high as 700 hp, maybe
higher, depending on race category.
Torque #'s on the base spring/gold, is 675 ft. lbs
the green full race spring upgrade tuning kit is 725 ft. lbs.
Red has not been available for the past year, out our door.
The upgrade tuning kit will not effect daily driving, but is probably
more than enough for grandma's ride. So eventually, all units will
probably step up to the upgrade spring, when more levels of
development and research have been endorsed.
The Phantom Grip diff-saver is a replacement shaft only, some with
retaining end clips that help to keep your diff-pin from coming
through the tranny, making a nice hole in the side, and a nice hole in
your pocket.This has been a problem mostly for Saturn and Neon, where
the diff-pin's (or aka as the centering shaft within the differential)
dowel hole is not precise to the dowel pin which holds it in
place.With much force and binding, this causes the mess. Our diff-
saver has 3 unique patent panding designs which are more precise - the
dowel pin hole to the dowel pin.
journal grooves provide more lubrication to prevent binding, and(when
the clearances allow for it),
end retaining clips to help ensure the pin stays put. help bulletproof
your tranny.
Hope this has helped to answer your questions. If you need more info,
let us know.
Thank you for your support and interest in Phantom Grip products.

I hope that answered some of your questions!! :biggrin:

OUT

I have never question Phantom Grips power holding potential...

..but doesn't it wear out and need pads or something to be replaced?

I figured if so, it will be expensive for having to reinstall new parts since our tranny is a pain.

Anyone got an information to disprove this or prove the wear out? I think that would help alot. :)

By the way, thanks for the information from Phantom. :D

I don't think it should wear out. There are no pads. Essentially, the phantom grip is 2 very solid steel blocks that go around the shaft in the differential. The springs between the 2 blocks push them apart and they wedge against the spider gears so that both sides and thus the wheels get traction. It is metal on metal contact but the pressure is immense so there shouldn't be any rubbing or anything to cause wear. The blocks themselves are very tough stuff as are the springs. I have had mine for a year of ridiculous hard driving and no problem of any kind. Of course nothing is indestructible, but I think they will last as long as the car for anyone other than a pro drag racer or someone with an absolute ridiculous amount of hp. And good info Macatron.

also from the phantom grip website:

The Phantom Grip is extremely strong and durable and comes with a Lifetime Warranty for breakage and manufacturer defects.


I'm not trying to sell anybody on the idea. I don't work for phantom grip and have nothing to gain. Just getting info out there for whoever may want it.

And good info Macatron.
Thanks! :biggrin:

well, i guess my only beef with the phantom grip is the metal on metal contact. how can that be good? also, it seems like it wouldn't do well on corners because it wouldn't be the same as a launch. it seems like it would just grind or not work at all. well, from what i've heard so far from you guys it seems good. i just drive my car really hard and i just don't want to have to worry about it ya know?

As far as how I understand how the phantom grip works (and I could very well be wrong) is that it pushes the spider gears against the differential housing. What keeps the differential "locked" is the friction between the backs of the spider gears and the differential housing. When one wheel does spin faster than the other (like around a turn) then the backs of the spider gears are rubbing the differential housing with a lot more force than they were designed to do. So if something is going to wear down over time it won't be the phatom grip, or the insides of the spider gears where the phantom grip pushes, but it will be the outsides of the spider gears and the differential housing. Of course the phatom grip itself is warrantied. But I highly doubt that they will claim any responsibility for excessive wear on your spider gears or your differential housing.

Just excatly how much the phantom grip accelerates the wear and tear on your spider gears and differential housing is unclear. It could very well be negligible as they say they have many customers that have had a phantom grip installed for lots and lots of miles without any problems.
