The title pretty much says it all.
Over on the other forum: YANK (from Yank Converters) posted that he's seen the new cast iron diff. I pm'd him and got some details: http://www.ls1tech.com/forums/showpo...1&postcount=28
I'm cross posting here, in case others haven't seen this yet. MOD, please beat me a new one if this type of post isn't allowed  I PM'd YANK, and got the following info on the cast iron diff (posted with his permission):

it is much beefier and can be made to work in the early model chassis.
I can not release photos as it is not released into final production at this time.
but the car and powertrain is quite a step up. Very interesting.

And not sure how easy it would be to hang a beefy hunk of cast iron in a space designed for a hunk of aluminum.
I saw that guys (Yank's) post earlier and wondered if he was serious..offered no details in the thread. |

Can anyone here with some GM connections try and get a confirmation? Yank is a failry large outfit, it don't think it's out of the realm of possibilities that they may have some inside knowledge.
Finally, I wouldn't expect that they would want to make anything too big, which may explain why they just moved from aluminum to cast iron. More strength in the same sized package. The car is already a mamouth beast, so whats 10-20 more lbs over an aluminum package?
Who knows. I guess this is all just speculation until we get more details. It does dovetail with that cast iron unit that they put in the SAE100 STS last year though.
If this does come to pass, I think I'll take all credit for it, since I asked them to give us cast iron, in this 'open letters to cadillac' forum thread: http://www.cadillacforums.com/forums...tml#post823621 (CTS-V Differential Issue)
I mean they really read that, and take action right? 
Seriously though, wasn't Rick floating a rumor like this about a year ago? I guess if this was real, we'd have to give him a big-up.

A lot of what kills the drivetrain components in this car is the interaction of weight and power, esp..from a dig. I hope that in addition to the differential carrier, they will strengthen the half shafts too, etc..etc..otherwise the problems will just move upstream or downstream.
I remember Rick saying something about cast iron, too. And Marty, of course, but I think he wanted to fab his own. |

While I haven't gotten confirmation on the next gen CTS-V diff being cast iron, I do know that it's an electronically controlled locking diff so unless Stealth is planning on hacking a next gen ECU so we can add the wiring to control the new diff I'm not sure it's real viable as an option. Certainly not a trivial swap anyway.
p.s. did you note the STS SAE100 cast iron diff had wires going to it also |

Thanks, Ron, for the input... |

Whatever happened to the forum member who was gonna talk to a cast iron vendor?
Ahhh, WISHWARE. 
I am kinda suprised that GM performance parts or GETRAG doesn't offer a "high performance" upgrade.
They would have a ready made market for at least 20 (LOL)

Cast iron is available in retrofit from CTSV05 (Doug). He will be using the C3 Vette rear on my V and will be making the kit for our generation V's. New half shafts, solid mount and 1 piece driveshaft will be installed. Should be reasonably priced and readily available. Details soon as I get back from vaca and Doug gets my V to play with.

Then the computer will have full control of everything reducing the stress on the drivetrain. With AMG, M, and Audi's S all being influenced with some type of manual matic, figure Caddy will not be left behind with the only manual trans.
Figure on mild updates on the diff and exterior enhancements for the new. CTS model as this is what the General usually does, nothing major.

I must be like Creskin or something!
Failure points though, because it don't fit.
Ohh well.
