Don't ask how it works, because the car is still on jack-stands and not yet registered.

My belief is that this support should almost eliminate pinion deflextion and the cradle being tied together at the bottom should help reduce ocillations/harmonics associated with hard launches. With the exception of 4 holes drilled in the cradle (because it is boxed,so you have to go through both lower & upper), this is a Bolt-On.
I don't do hard launches so, I'm a lousy test pilot.

I started thinking about this 6+ months ago and began researching and putting it together about 3 months ago.

With all this rain in NJ, I probably will not put the car on the road until late next week.
The whole project has been kinda a pain in the ***.
At 61 yrs. old . . crawling around on a cold concrete floor, cut, grind, measure,
back under to fit and do that ungteen million times and the joints are hurtin'.
Hey! I did buy a new welder that is really cool, though.

 

Let us know how it works!

 

Not to poopoo anyone's efforts, but the "solution" couldn't be that simple. Granted, some engineers leave a lot to be desired, but simply doubling the bracing has SHIRLEY been thought of (and don't call me Shirley).

Otherwise, hope it works . . .

 

Stepside where are u located?

 

I didnt know you are in Jersey, Im in bergen county if you want i can test the crap out of your car if you want me to.

 

I'm gonna go out on a limb here and say New Jersey. Just a guess though...

 

in that case lets make something of this im from somerset county and im always around the westwood area in bergen county i wanna check this out also.

 

Bergen & Somerset are still a long way from me, since I'm in Sussex Co. west of Newton.

Here's another picture from the back of the car.

 

Let us know how it works....

 

hate to tell you this but you will blow your diff to shards the first hard launch unless u have a bushing in the 4th connection, u need some movement

 

Looks similar to the Kars III kit.

 

If u look at the first two pics, it shows that there is some type of bushing in-between the diff and the support.

 

You are correct! --- Vulcanized rubber. Same as a motor/trans mount.
And I took the car out for a ride today. Also, changed all fluids - engine,trans,diff.
I haven't driven it for 4 months, but I did not notice any difference from stock. No increase or detectable difference in cabin noise.
Maybe I should go faster. I wonder if I'll be able to here any wind noise if I go 100 mph.
I think this is better than Kars III. I looked at that, but decided I did not want any attachment to the front pinion area.
I do not like the BMR pinion support either. I looked at this differential a long time before I created this.

This is my opinion based on obsevations of V1 broken cases vs the newer designs.
On the V1 -- The rear is suspendend in the cradle at 3 points. All of the points are above centerline.
I also, do not believe that the front pinion support is the problem support.
It only becomes a perceived problem when the bushing wears out.
The two rear supports are higher above centerline than the front support and the right rear support is not only high off centerline, but far away from centerline.
Because it is so far off centerline, it has the leverage needed under massive torque load to twist the case apart. If you do not believe that, then take a look TC Perfomance web site of his broken case. I think his girdle works because of what I just stated.
My support is mounted to the left side of the case through vulcanized rubber and connected to a cross brace. There is also a 'corded rubber piece of belt' between the brace and cradle.
If you look at the V1 cradle, it has no support or bracing below the centerline of the differential. To me, it is obvious that it was designed for 200 lb ft of torque and not for 400 plus lb ft of torque. If you are still in doubt, then stick your nose under any of the new CTS's (does not have to be a V-Series) and tell me what you see.
Bottom line. Does it work?
In theory it should, but as of this time, I do not know.
I think time is on my side.

 

hey just wanted to see if there are any more updates and how is this working out for you?

 

I've only put several hundred miles on it since I put on the 4th support and still do not notice any difference from stock.
The car has 19k+ miles, so it is still a relatively new car for a 2007 and nothing is really worn.
I've been contemplating on tying the front of the cradle together and then to the unibody, but not a hard mount.
I would also be able to tie that to the 4th support, but . . undecided.

There would be either urethane or rubber between the cradle & unibody.
Everything is total overkill for the way I drive, but I like the idea of the added support if I hammer it.

 

So a year later, how is this working out?

 

I have the TA Girdle and I haven't blown up the rear yet but I did blow the driver side inner CV.

 

I sold the car in November of 2011. Had it shipped to Washington State in closed carrier.
What I designed and built was only the 1st in a 3 part process.
The car still exist and the new owner has been given all the info should he want to take it further.
He will probably put g-force axles on it in the near future and futher development on the 4 support is up to him.
We still keep in touch.

Oh, i took delivery on a 2012 Raptor last November 2011 to replace the V.
The Raptors were late in production and I think I received one of the 1st ones, thanks to the Dealer.

 

thanks for the update stepside
