Tony, how hard/difficult would it be to alter the spring perch ... I can't recall what that looks like off hand ... are we talkin' a lot of cutting with a torch and then fitting and welding under there? ... UGH!
Does having a Ground Control, (or other) coil-over spring perch make it easier to retrofit?

Rand is right, that almost is the only mod we have left.
If we can have the improved drivetrain of the new V in our lighter chasis with similar or better WHP :cloud9:

I was already eying the 09V brakes and hubs, so I don't mind them bieng part of the plan.
I'm mostly glad to hear they will fit.

I'm thinking the spring perch relocation will just be a matter of an offset bracket with something similar to a Ground Control adjustable spring seat integrated into it.

Why are we focusing on the V2 parts? Has the 2008 cts not been revised? i am sure there are plenty of those available wrecked now.
This suggestion still has some merrit.
At least the cradle and gas tank could be the same.

CTS-2 diff would not be cast iron though.
Probably still stronger than V1 diff.

If the CTS-2 has stronger splines too, then that makes 2 good reasons for doing it.

The cast iron diff could always be put in later, if needed.

Obviously if you have big power then there is no option but to wait for the V2 parts.
With low mods, this might be a good low cost upgrade w/ cheap CTS-2 parts.

How about we have a raffle and the winner gets this upgrade done at Lindsay.
That will then pave the way for others to get their cars upgraded after. :)

Maybe didn't read this closely enough, but if this is primarily just a diff swap (from a drivetrain standpoint only i.e. excluding the fuel tank), is there any way to provide axle shafts with substantially different torsional rigidity in order to reduce/eliminate wheelhop?

I mean, if the biggest difference is simply going to be the diff, these cars are still gonna hop like a 'roo on 'roids.
It's true that the car could still hop.

However, a full 09 retrofit (mayb even a 08 retrofit) with improved diff to cradle attachment and updated half shafts, should make it much better than it is now.

Contemplating a quick fix for my newly imploded rear. Sourcing a used rear to let me drive the car this summer.

Hope to go ahead with the ''09 retrofit by...... fall/winter?

I'd be willing to drive cross continent for the work :) Can I camp out in the Lindsay parking lot, as long as there's wifi and power I'm good to go! (seriously tho, anyone thought of the logistics of getting this done far away from the east coast?)
I'm already qualifying 2 potential shops to do the work, once the parts can be purchased.
This is one mod I can't wait for. :bouncy:

When looking at that 09 V, could you see if the front hubs, brakes & rotors are also interchangeable? :cool:
