superu Posted March 16, 2009 Share Posted March 16, 2009 Anybody currently using one?Pro's,con's,general feedback from someone who's used this. pinister used it but he hasn't posted for over a year. I've heard good things about the phantom grip used in offroad applications. A friend regularly puts them into his built up rigs (EJ swaps into EAs and DR swaps into new gen cars), but he's not on this forum, so i appologize for a second hand report. One of his rigs is run by freerange I think in Montana [(an 98 OB) has phantom grip front (i think) and rear with a DR 5spd from an EA] is smetimes on this board but more on legacycentral.org. He likes it well enough. He reports, "it's possible to burn off the front tires(phantom LSD) but axle hop and torque steering comewith it." I too have been weighing the phantom grip vs. a stock suby lsd (not vlsd) for a rear LSD in my minor-lifted legacy, for use in snow and minor off-road applications. But I've come to expect the PG would be better for off-raod but good in snow and the suby LSD primarily good in snow. I am considering it ONLY for the rear, as it is my daily driver. Anyhoo, I don't know if this helps but it is second hand reporting of Phantom grip being pretty good for offroad application in a suby. Link to comment Share on other sites More sharing options...
frogstar7055 Posted March 16, 2009 Author Share Posted March 16, 2009 Ya I just want to run it in the rear as well. Think I'm gonna do this. Link to comment Share on other sites More sharing options...
monstaru Posted March 16, 2009 Share Posted March 16, 2009 i have heard from the racing crowd that it does not work. they nicknamed them "phantom slip" these are high horsepower cars, i would think that in a dirt situation you would not see any difference if they are not seeing a difference on the street.... they say that the springs are the weak link. what are going for here?and why are you not trying to utilize an LSD from a subie? is it the fact that you have no options for your axles?true =the stubs on an lsd unit may hinder this but i do not believe that you could not take some earlier rear axles from an impreza or legacy wagon and utilize them out back. someone pipe in here and tell me if it has been tried or not. i do not know,but have been inside of our differentials several times . or for about a hundred bucks more why not try to find an sti rear diff with lsd.....or are those viscuos? anyways, just some food for thought i guess.good luck with whatever you do.everyone likes traction!cheers, brian Link to comment Share on other sites More sharing options...
superu Posted March 17, 2009 Share Posted March 17, 2009 Are you running a 4.11 final drive or 4.44 in your forester? Both are findable in Suby LSD, they'll vary on LSD or VLSD though. Someone else help me out here, but can't you get an 02 WRX (probly a 3.90 final drive?) auto (I've read that's the one you want) and pull the LSD unit then replace it in his rear diff with his correct outer ring gear (not sure what its called), or a similar deal with another factory clutch pak LSD? Scoobyclimbs has a 4.44 LSD in his 03 OB, I think its Suby... Anyway, I'm interested in this mod too, either creating your LSD from another Suby diff or doing the phantom grip install Link to comment Share on other sites More sharing options...
carfreak85 Posted March 17, 2009 Share Posted March 17, 2009 For the front diff, a Phantom Grip will be the cheapest route short of welding the diff. Other options exist, but at a much greater cost. From what I've heard about PGs, under repeated drag style abuse, the PG will actually start wearing the diff gears which will produce metal debris, which isn't really that good for transmissions. I've never run one myself, but have done some research on the subject. Link to comment Share on other sites More sharing options...

Really just want a lsd in rear,just can't make up my mind which way I'm gonna go. Link to comment Share on other sites More sharing options...
