Sounds like this is the post that stops us chasing our tails.

Count me in.

Interested in more details on the design once he finalizes it.

Just like always, ill commit myself to this. To be honest though, this possible group buy is a risk. It seems like we would be test dummies, for a product that may or may not work as intended.....Then again, i assume that those on this forum like to live life on the dangerous side.... :shoots: :smokes:

EDIT: On a side note, my interest might wane, depending on whether or not the quiafe diff ever gets some grounds.

^ I think most of us are aware of that there is a certain level of risk that the part won't be as expected. But the reality is that we're basically at the mercy of anyone who is willing to make low-production parts for us. I'm willing to take the chance this will be a decent front LSD, since the alternative if I don't take that chance is no front LSD. :shrug:

We don't have to go on blind faith however. We should attempt to get reviews on Frana's work and business practices from other forums or people that have dealt with him before.

Found some info on the http://www.calibersrt4.net forum. A company called Realtune ran a group buy for these diffs since the only option they had was a phantom grip. Here are some of the posts by Realtune during the progress of their group buy. This was back in October of 2010:

REALTUNE 10/6/10 wrote:An update : Design work is done.

I will start taking deposits this weekend. We will be doing batches of 5 at a time. Wait time once I send the deposits in will be 8 weeks.

These will carry a one year warranty against any manufacturer defects. That doesnt mean you can drop it off a building and we will warranty it

The LSD will be a helical gear (quaife style) for those that missed it.

I will have total price etc. up once I start taking deposits.


realtune 10/28/10 wrote:I am ready to take deposits on the Realtune LSDs.

Price will be $1400 shipped to your door in the lower 48 states. Canada/Alaska/HI please add $40. I will need $700 down to lock you in on an order. Wait time is 8-10 weeks once we have 5 orders filled.


These will be direct drop in. No machine work needed on your end.
"Quaife" style LSD
1 year warranty against breakage [does not include labor or shipping one way]



This will most likely be your only chance to purchase a true LSD for your Caliber SRT-4. I will start with 5 units. If they sell good we will make 5 more and so on but your time frame are months in between.


Please contact me or Whoosh via PM or email Realtuned@yahoo.com

If someone does not have paypal, I can add it to the website for you to pay with a CC but will not do so unless someone needs it.


Realtune 3/30/11 wrote:Bump. I have one spot left


Realtune 7/25/11 wrote:Ok guys!

I got side tracked but I will be double checking a few things the next week or so. All LSDs are done waiting my approval to start shipping.


Now is the time I need to collect the final payments.

If you have paid, please shoot me a PM and we will discuss final payment.


Please do not delay!


Realtune 10/6/11 wrote:Finally an update as I was able to get the diff out of the test car tonight:

We have one area that needs to be touched up machining wise. This will take a bit of time but other than that we are good to go. I am happy with the pre-load and characteristics of the LSD but alas they were not machined 100% correct and if we dont touch it up....it could cause future problems. I doubt anyone wants that so I think we [1st batch owners] will all be in agreement that the extra bit of wait is worth it

Thanks again to all those involved for hanging in there as I realize we are waaay past our timeline.


Realtune 1/16/12 wrote:Ok I have a dilema guys.

I will have these back at the end of next week. Everything should be good to go but simply put....I do not have a test car ready to go until the end of March as its bare chassis right now. I can test fitment [which is what I was fixing] but not opperation [which was good from previous testing]

Does anyone who has purchased one of the 7 have time to install right away and give me feedback? Again from my testing before we should be good as what I was fixing had nothing to do with opperation. Im 99.99% sure they are ready to go but before I ship out all 7 of them I would like to be certain

I will offer free shipping and a Realtune T-shirt to whoever can help me out. Otherwise we might be stuck until March.

The install is basically a clutch install [pull trans, split case - no special tools, remove stock ring gear and install on new LSD, reverse removal process] Should be very easy for anyone with a bit of mechanical wit.

Any helpers [only those who have paid already] ?


Realtune 2/2/12 wrote:LSD test fitment is golden. I have a car Im going to do the final testing in next week and will have an update after that.

Thanks guys!

As a heads up, if all goes well as planned, I will be starting another batch order shortly after. Im hoping to be taking orders within the next 2 weeks


Realtune 2/11/12 wrote:LSD has been getting a beat down the past few days. Fitment is perfect and function is perfect. Going to give it a few more days an/d pull her back out for final inspection. I expect everything to be good to go and the pre-orders to start shipping /late next week /early the following.

Its been a long journey but well worth the wait IMO.


Realtune 2/16/12 wrote:Ok guys, the DIFFs are in and ready to start shipping!


Anyone that ordered, please contact me with your full mailing address and the date you paid. I will get you the shipping quote and get the package out as soon as we are square!


I will have pics up tomorrow for others to drool over

So we're looking at $2500 for front and center helical LSDs? I'm definitely interested and can swing the money.
Will it be the same setup as the TRD ones? Or in the same setup as factory? Or we don't know yet?

In order for the the parts we need to be developed, we need people who are willing to be test dummies... There is no way one person can afford to, or source enough GT4s with different mods, driving conditions and geographic location to give us a good test base UNLESS we all chip in and go for it. If shit breaks well hey that happens, its only going to further the development of the cars we love.
It just sucks that our community is so small so we generally have to suck a bigger portion of the damage up. Besides that these guys know what they are doing im sure they have some confidence in what they are putting out otherwise they shouldn't be in business nor would they be for long. On that note, ive got a budget and buying just the lsd will blow that, so it will have to wait good luck guys

OK I talked with John on the phone today. He said to do just a front lsd is just not feasible. So in order for him to do it, he has to make both a front lsd and center lsd. The design will be just like stock. So both diffs will be in the transmission. The viscous coupling unit will be eliminated completely. He is willing to do a run of just 3 to 5 units for an estimated price of $4000 a unit. The more people we get the lower the price will be.

I'm willing to still do it at this price because I know this is about our only shot at this. But I truly don't see it happening. Even at 3 units. So if you're interested let me know and I will get this underway. But I will not push this anymore and I'm just planning on running my Cusco rear lsd, upgraded Mario center VC unit and stock open till people step forward to me.

I guess we can hope Quaife can come up with a design, and is willing to sell them with a group buy of less than 15 units. But again the shot of that happening is about the same as 2 others to agree to do this Front/Center combo at this price.

I love my Alltrac but this is where I hate having such a rare car.

Ouch

Yeah, I don't know about 4Gs man.
I can swing 2500 but 4000 is probably more than I can do.

Did he mention a setup like the TRD one?
With the center diff in the trans and the front diff in the T case?

I figured on the price and totally understand.

No. It'll be like stock. He said doing it like TRD would be too much to do.

So sad I was really thinking this would have been sweet but 4000 is just to much for me to justify on a street car. I guess im out.

Well, maybe rather than a "commit" thread, we should switch to an "interest" thread and see how many we could conceivably get.

Maybe if we can get up to 10 we go back to Frana and see how low he'll go.

If the Quaife pans out I'm sure we'll all go with that but if not we may get more interest here for a larger group buy from Frana at a lower individual unit cost.

Anyway. Count me as 1.

Count me in. If its going to take a while to get this developed (around 6 months) i can stick to that. But once again, if the quiafe LSD thing goes through and comes out cheaper...I WILL drop out of this. Even if i have Unless i send a down payment through....Ill stick with it to the end if i do that :twisted:

I'm going to wait to see what Quaifes response is. If they say no like MFactory, I'll try again to get interest in a purchase through John. With everyone having hope that Quaife will still make one, there is no hope of getting enough people for this. I bet when they say no, people will realize that this is their last hope at some front and center LSD's.

Can anyone comment as to how they think a center torsen/helical would handle street driving and differences in road surface traction?

I feel that by going with a center helical diff you're going to end up with a car that is at times very FWD biased and at other times very RWD biased.

Would there be any condition where one could actually do damage to the center helical diff?
