So Ty are you mainly talking 4t-60? Now how do you feel about the LSD'* available for my 01 ssei with the 4t65-HD? Would you compare say, the Intense version which I know is dual clutch type, The Qualfi (sp?) one I know makes 50/50 power distrubiton all the time giving you wheel hop on turns, But I don't know what type the C-Ya racing one is.

I've been reading on the Illinois Grand prix club, and Mike Dye aka Miker is a member and owner of C-Ya racing. Know him? Well I hear that he'* a very nice guy and will do cam installs and stuff too. But he Says that If your local and come to his shop/house he'll sell C-YA LSD'* INSTALLED for $400. A lot of the local guys got em and say there great. For $400, I don't think I can pass that up.

Just wanted to hear what you have to say about it first.

I will share a little secret (well a secret to the consumer)

Mike dye is the only guy who has innovated in the area of the limited slip because he applied the clutch material to the 4t65-e. The guy who builds our units uses the same clutch material made by mike dye. The only difference is there is the full posi ability with the calibrated springs on both the 4t65-e and 4t60-e, HD or not. We also do 4t80-e and 4t45-e.

Our unit costs more but the calibrated springs and a similar unit costs more.. basically 599.00 for a true preloaded limited slip.

If you are thinking of going phantom, run don’t walk and wait and buy a mike dye unit.

They are the best middle of the row unit. I have my personal preference based on other users of limited slips and Mikes is better of the bunch because of the clutch material.

Still the very best option (my opinion) is a truly preloaded limited slip.

90% of my product is not made by myself. I outsource much like toyota would to companies who I research . The company doing my limited slips for me has a relationship with the maker of the clutch material and adds the calibrated springs for the true posi effect. They also make kits using specific parts with brass rings or brass impregnation on the pinion so if you blow your limited slip you have a greater chance of saving the rest of the transaxle.

I have taken so long to bring it to market due to the testing. I also have a test customer who has destroyed many units and i want ours to last.

For 500hp and less we can already provide unit for $599.99 and it will come with all the parts posted on other popular units but it will also be a fully preloaded unit VS other options.

Just for the record many companies claim to be the best or the first in the 4t65-e limited slip market. Mike dye is the guy who really made a difference creating the proper clutch material needed. Without that there would be no ability to truly preload a limited slip even with the calibrated springs. It just would not work.

I just wanted to place credit where it was due.

Yes quif who came after Torson both offer a 50 50 unit and it is what they use on the 900hp ecotec car..running a 4t65-e. Without the torson unit they would not have been able to pull it off.

The unit we use is just like the intense and mike dye unit in principal but we add the calibrated springs so there is no staging required and no pull from one side to the other on take off. The posi unit is the best way to go and has been used in old Chevy hotrods for years.



I talk about a lot of product and I sell product..but as you can see here I don’t care if you buy from me or not I just peruse to offer the best options available. If you can afford it a preloaded limited slip is the best option short of a 50/50 unit. The next best is the mike dye unit. The rest is a waste of time in my opinion.

But if it only a couple of hundred more for a true LSD then its well worth it. Are these on your website or is this more of a persoanl request.

I have to wait to load any new product because again the company doing my site have not finished and a new programming issue came up.. So instead of add more parts I have slowed down while i wait for the new site. Still waiting. The site is complicated because it is designed to send orders and money directly to my product suppliers or developers. less paper work and less time on the phone. I am also trying to do it for less than 10000.00.

So I will send a paypal link to buy the product and then you can buy it that way. It can take up to two weeks to arrive.

Thanks for the info Ty, So After hearing what you have to say, I think I'm going with the Mike Dye LSD because he is local to me and will install it for $400, that'* by far the best deal and from what you say is a good LSD, I'd like a Qualif or some 50/50 but there 2-3 times the cost, that'* cutting inot my intercooler money.
Thanks for the info again.

yesterday i called phantom grip and talked to a tech that does the actual installs. they have 3 different sets of tuning springs. the extreme springs make it very tight and the unit is set up to have a .005-.010" space between the unit and the side spider gears BEFORE the unit retention clips are removed from the it. when you get it, it is loaded and has retention clips that hold the unit together so that it can be installed. once the clips are removed, the unit loads itself against the side spider gears with the springs inside. the preload rating is of the spring pressure that you use. he also told me that the unit material is heat treated and conditioned to be used with the spider gear material. this conditioning gives it the funtion of clutch material but doesnt wear out like a loose clutch pack does.
after talking to him, i am going to go with the phantom grip unit with the extreme spring setup. i have 2 graphs from phantom rip. they are of straight acceleration and a with and without the unit installed. the graphs show wheel speed VS car speed.
this one is without the unit installed

this one is with the unit installed

the tech also told me that from his on hand experiences of installing these units, the average reduction in 60' times are 3/10-6/10 of a sec over an open diff

Ok I am not an engineer but the phantom has the actual real world effect that the intense unit has and it works but in the wet you will often only spin one wheel. This also means as you glaze the steel the unit will not work much better on the dry.

Yes "real" limited slips need maintenance and all good limited slips require clutch material. Once again look into the 4X4 world and you will find this is true on all the limited slip units designed for severe use. No I am not talking about dogtoothed lockers like the lockright. Just the limited slips.

Phantom will work as I said but it will not ensure you don’t get slip from one side to the other.

I have another option coming that will give you both worlds of a fully locked diff for the 1/4 mile and a open diff for the road. No maintenance.

I have the same company who makes our transaxles working on the unit and getting a cost.

If you want one i can have it made in a few weeks but if not I will have to wait until I am finished with all the other projects.


Basically the point i am making is the phantom works partially but the unit cannot beat the physics of the situation.

Steel on steel creates steel filings and severe heat/ friction. Steel on clutch creates some mostly harmless screenable clutch particles.

Jeff this is not a jab at you and I respect your doing your own homework. Take my comments back to the phantom guy I am sure he will talk as intense has about the “minor” requirement for staging.. But this adds up to what I talked about and thus the phantom or intense unit will work..but they are not proper preloaded limited slips.

-The phantom is the cheapest, but does not function as a as well as a true limited slip.
-The intense unit comes next in cost but is in the same as the phantom in the traction.

-Next comes the Mike dye unit “A true innovation” for this diff and it can be made to work very well. When he makes you one ask for the brass coating or sleeves it is a option that can save your transaxle. It will most likely cost more but if you are hard on your car it is a must in my book.

-The next unit is the DP unit with calibrated springs and clutch material.

-Finally a 50 50 unit preferably Torson if you can get one.

-Dp plans as said to offer a control by button 1/4 mile locker for all the GM transaxles. I will have a price for ya soon.
