i emailed them and gave them the info that we too use the r200 as well as the 300's and maybe this should be a direct fit since i cant see any difference between the r200 we have and the one the 240's have other then the gear ratio

it pushes the 2 spider gears into the wall of the diff creating a lsd effect where power is routed to both wheels rather then just one..and if you spin out the extra spinning motion causes the phantom grip to expand more and cause even more pressure on the spider gears....you can go to www.phantomgrip.com to get more info

hmmm ... I dunno if I'd recommend it. I know in the race car, we used to weld the spider gears together, much to the same effect, but it really sucks for cornering, because when you go into a corner, the inside and outside wheels spin at different speeds. With the spider gears forced to spin at the same speeds, your inside tire will start to hop. On an oval track, it's not such a big problem, you just wear one tire faster than the other, but it can make you really unstable when you're trying to change directions, like in an S.

ill check it out then! sounds like a pretty cool little unit. and we wouldnt go through the hassle of having to fit a rear axle. I wonder how much a 'yard would charge for a rear LSD axle. perhaps we could get out for one cheaper than this. (just trying to play devil's advocate)

if you can find a lsd froma 300 or 240 in a yard then ya it proberly would be cheaper abd you would only need the diff itself not the whole axle....but they are hard to find and would most likly require a rebuild so this may be the next best thing

Very interesting, kinda vague tho. This isn't really my area of expertise, But like Bart says, the plates seem to work on centrifugal force over coming the tension of the springs to press up against the spider gears. I think. But I am pretty sure during hard acceleration, or for that fact, any sudden jerking motion will cause the plates to pivot or tilt in to a position that will lock-up or in my eyes bind-up the spider gears hence creating a solid axle. Yeah, I'm with Mr.200. I dunno if I'd recommend it.

What's not to recommend? It opperates like an open diff untill load is applied or one wheel starts to slip at which point it locks the spider gears and allows traction to be routed to both tires at the same time. I have seen this done a couple of differant ways. Detroit lockers were very popular with off road trucks for a long time and work very well in this role but are quite noisy. I have also seen another locker modification kit for american cars but the name eludes me at the moment. Again it works very well but makes a chattering noise around corners. This looks like it would work well on the street and be quiet on top of it all. If the money shows it self to me I would buy this product in a heart beat.
Just my thoughts.

Its cheaper and easier than getting a LSD out of a turbo 300ZX, and, should it happen to blow later, then you can always just get another diff out of another S12 (they aren't that rare yet)

Well I have a straight axle on mine and also wanted to convert to a manuel on mine. Would it affect diiferently on a straight axle? Also give me the name and company of that so I can research it.

I guess it's the economical way to go, But it just sounds ghetto to me. It makes me feel like it's trashing up the inside of the diff. But if you're comfortable with it, try it. And please let me know, if it works with no adverse or long-term side effects. I'm curious as to how effective it is.

I know what you're trying to say Randy, and I think you're talking about the Lock-Right, Trak-Lok, or anything of the el-cheapo diff varieties. These are drag race application, where in a straight line you always want both tires spinning at the same rate. But, when accelerating through a corner, you want your tires to spin at different rates. Your inside tire will spin faster than the outside with an LSD. With this style, the car will try and pull itself straight. If you fight it hard enough, the outside tire will start to hop, removing any help an LSD would give you cornering. The fact that it will act as an open diff until a certain amount of pressure is applied, is even worse.
Think about it, you're coming out of a corner under some throttle (diff is open) you whack the throttle, the rear locks, and all of a sudden, you get a whole lot of pull on a side that didn't have it before. If you manage to keep it under control through the turn, and the back tire hops, you'll start getting pulled sideways, and not under control like a drift.
There's a reason these designs are cheap.
And as for not buying an LSD out of scrap yard, because the diff will have to be rebuilt ... even swapping the Phantom unit will constitute a rebuild. This in not something an amateur mechanic can do in his driveway. You have to dissassemble the pumpkin, replace all the seals you disturb.
I installed the Trak-lok in the Charger with a few friends, and it took us 4 hours alone to get the pumpkin apart and together again, not including getting it off the car, or back in. (granted we changed the ring and pinion too)

i got word back from phantom grip and they said it would work on our cars....now i see exactly what you are saying matt and this may be a down side of this lsd but it was something that just poped in my head and i just wanted to let people know that there is an option other then one in a yard for a lsd especially those of use here who wont be doing autocross, but rarher hitting the dragstrip...

Wouldnt recomend anyone to weld the Diffrential togheter if you arent planing on going all DRAGSTRIP/RACE style.. becose it will not manover that good on a circut with a welded (or the type that is describe in this treath.)..
but you will be able to do some nice Drifting! icon_wink.gif
/Joakim Johansson
I agree Bart, it is still an upgrade some people might consider. And yes, it would be pretty good for drifting, depending on your style. If nothing else, it is a very predictable rear end. It will always be consistent, so with some practice, I can see it being a fun mod.

Yeah...I think it was Lock-Right.....sounds correct.
300ZX guys have all done this before.
