These LSD are dirty cheap, thinking of getting it. check this out http://www.phantomgrip.com/

It only cost $299 US, that's a real good deal, right?

If anyone knows anything, good or bad about this product please post.

I've only heard of bad things about the Phantom Grip unfortunately, and it involves buying a new differential after it was used But I think those accounts were based on hard driving conditions. I'd much rather try and purchase a true aftermarket LSD.

Unfortunately, you get what you pay for. Don't skimp out on your drivetrain, where you can't see the damage being done, cuz once it's done, it'll cost a fortune to fix. Either spring for a Type R tranny to begin with, or just get a Quaife or KAAZ or Cusco. Not sure Cusco makes a Honda LSD, but they do make them for other cars. Worth checking out.

Does the Type R original LSD fit into a civic? What is the best LSD out there?

imported_SW20 MR2

I don't believe it will fit the housing on DOHC Civic trannies. The Quaife vs. Kaaz debate has been going on for years now with no end in site. Everyone has their own opinion on the issue, and you won't be able to get a straight answer.

I would like to know some more info. don't know nothing, but how it works.

The Type R tranny will bolt to any B serier block...no matter what car it's in.

As for LSDs, there are several different designs. Clutch type, Spherical type and Spring type. The Phantom Grip is cheap, and does not require re-shimming the tranny. I think Horsepower TV on Speed Channel installed it in their....I forget what car, but it was a FWD. It might be good until you save up for a $895USD Quaife or for a Type R tranny. I'll probably try it out too in a couple of years (gotta get EZ Lockers or LockRites for my 4x4 first), so lemme know what you decide. Turbo magazine has tested it too I think. Jerome Soh sells them as well, and I assume he uses one too. There should be lots of info out there, so just do your research.

Yes, that's correct. I was referring to just taking the ITR LSD and putting it into an SiR tranny. Here's some more info:

Well, there is little more for me to say, unless you have a very specific question. Quaife has been in the business for a very long time, and they probably have the most reseach and dev time in their pieces....if there was a cheaper way that was just as good, I'm sure they would know about it. This of course is second to Honda OEM parts, so if you have cash, I suggest taking that route. However, if you push past 300 hp, the OEM unit is probably outside the design parameters, and Quaife then becomes the way to go. KAAZ builds a unit similar in style to the Quaife, but I don't know of their reliability and quality. I do not own a LSD at this point. Phantom has had great reviews for the money. The key is, for the money!! It's simple to install, works just fine, and is cheap. So, what the hell...if you are going to save for a Quaife or OEM, but want LSD now, then $300 isn't too bad for a Phantom Grip unit....and you can let us know how it goes. Oh, and now I remember....Horsepower TV installed the Phantom LSD in a Ford Focus project car, and they liked it a lot. So it's not a scam or anything...the product works. It's the price that makes me wonder, that's all.

I was thinking, LSD are all made from the same metal right? Not like they are going to break, unless you are running them on more power than the were meant for. Having said that, what I really want to know is the following:

- OEM LSD, besides quality is there any other benefits, in terms of setup (grip setting). Do they provide better grip.

- which LSD is best of mad corning?

- I don't really have faith in American product reviews, think about it, PT cruiser and Thunder bird got the car of the year award They are mostly commercials, but then again metal is metal, it can't just break can they? That is the most important out of all my questions.

Actually, metal is not just metal. Like MRT of Australia has unbreakable gears for the WRX, simply because of better materials, processes, and design. MRT gears is what WRX rally teams use in their trannys. The design of the gears as well as manufacturing processes, and heat treatment all have a lot to do with longevity. You also must understand that Phantom is a far different design than Quaife. Phantom just locks up the two sides as if your diff was welded together temporarely. Quaife, however accomplished limited slip in a different way....varying degrees of slip. Exactly how this is done, I don't know. By the way, the "reviews" I mentioned were not from media sources, but from users on boards like this one. I have not yet heard anything negative about the unit, but a few positive things. No links come to mind. Remember, metal is not metal....why do you think Honda engines are so much longer lasting than Chrysler (besides the obviously superior design and quality) it is the materials they use for bearings, piston rings, valves, cams, and so on.

Oh, and for mad cornering, I would take Quaife or KAAZ or Cusco, because those are true limited slip, that still allow some difference in wheel speed while applying power, ie. when under power and cornering at the same time. Phantom just locks up the diff, so it's only really great for drag racing.

If you want a lot of opinions for Kaaz vs. Quaife, go to ClubSi or Honda-Tech and do a search. You will find tonnes of information and opinions.

EK7_DriftMania

Thanks, guys
This mod is a must have for me, it is reach-a-ble in terms of price.

imported_SW20 MR2

Don't forget about the labour cost as well. Ripping apart the tranny will cost you quite a bit of money. At the same time, you may want to consider upgrading the clutch, flywheel and/or final drive as well.

EK7_DriftMania

true, I will post again after a few days, just need to look around.

EK7_DriftMania

I have read some of the reviews on other boards, the reviews are pretty good, really interested now. Quaife, Kaaz, and Cusco are very expensive... I know that Quaife has lifetime warranty on their LSD. LSD can't just break can they? I am planning to stay under 200hp or does that matter at all, the LSD's hardest job is in cornering right? Still not sure about the internal on the Phantom, anyone know if it is the same as the others?

Raocorp

why not just bolt an ITR tranny in your SiR?
thats what I'm planning to to....then you don't have to worry about things fitting and quality and **** like that. Not to mention, the labour savings of not rebuilding the tranny. Pull one out and slap the other one in.....should be done in a few hours if not less. takes half an hour for a good (key word there) to take out a tranny.
And, correct me if I'm wrong but, I don't think any of these aftermarket LSD's are better than what the ITR tranny has in it already.......
