If everyone did burn outs on wet patches of pavement, and then hit dry pavement at 5000 rpm then yes, it would be a common problem.

The stock Diff is a perfectly fine diff for the era these cars were built in.

Furthermore, the phantom grip is not a complete differintial replacement, but rather a instert that pushes on the two spider gears. This allows the car to transfer power equally to both tires when going in a straight line.

Because it is not a direct replacement, getting one will not make the diff any stronger, and not make your odds of shattering one again less.

SickSix: The quaife unit is almost $2000, plus you need to have the ring gear from your diff put on it by a machine shop, and grind down your tranny housing to make it fit. (Remember, Quiaffe only makes one for the 2nd gen, so these adapatations are requried to make it work).

No they are still in development. It was a group buy / development project. It has been a few months as they have tested and rebuilt the prototype 3 times.

PS can't wait to get mine... the spare rebuilt tranny is in the garage waiting for the transplant. Thank's Mazdameister!

Last I heard the total for the Quiafe was roughly $3000. That included the Quiafe, adapting of the ring gear, and tranny case modification.

Just got mine in. We'll see what 400+hp will do. Guys with similar hp are having excellent results with it. Welding diff pin in was highly recommened.

How are you guys with the PG liking them?

Hmm..

According to what JayB did, I know his name is kind of a sore subject around here lately.. But a shop in FL modified his tranny. They machined .030 out for one of the races, so that the quaffie fit in properly.. Total cost was like 2600 when all was done.. And yes he used the 2ng gen diff.

Phantom Grip sucks.. it's not worth the $300 .. i had it in my car...i had to cut the OE spider gears....once you cut it(use machine shop, cause i used drinder and had to redo it) and you drive in striaght lane its ok(help you a little on acceleration) but in corners its still the same ****.... i picked my car up and i moved my one wheel, the other turned in same direction, (so that good right??, ofcourse) but now i went and tried to stop the other wheel and....well in quaife or really good diif you barely can stop it spinning.. but in PG it takes barely any effort to make it rotate the opposit way( whcih is in case of regular open diff)...

anyway , mx6.... i got a complete brand new diff i'm trying to let go... for pics got http://community.webshots.com/user/probikgts.. and please dont think i'll let it go for $50 .. i ought it on dealers discount and that's how i want to let it go, it's uncut, uninstalled , only i touched it with my hands no oil or grease , nothing....the price i paid is on the pics of the receipt... i'm looking to get $150 plus shipping...which is little lower than i paid for....

MX666Y: You must have done something wrong. There are guys that have over 400whp fe3's having excellent results with them.


I think the Phantom Grip will shine more so on the drag strip than a road course, but it has to be better than a stock open diff. Also if there is slippage then upgrade to the "green" springs is maybe needed. I also heard that making the tolerences tighter will help out alot as well.

I think the best would be to get that AUS LSD, but to drop $1200 on it would be tough. No point for me beings my car will be rwd next year.

Fallguy no disrespect, but i'm not novice in the performance scene....PG blocks were nice and tightly fitted between spider gears...so if you ask me. i would pass on the PG....if it would enhance the life of the diff then yes i would by it but it wont..the only thing that i have came to conclussion in order to prolong the life of the diff on the drag strip is to fill the mounts with poly.....no tranny movement, no engine movement, perfect gear switches, barely any if none WHEEL HOP(#1 killer of the diff)....but that's just my suggestion...

None taken, but still not many LSD options out there.

I agree with you in that #1 killer of trannies is wheel hop. I have poly filled mounts and zero hop. That's prolly why mine has lasted so long.
