Would these spacers mentioned replace the bushings that attach the cradle to the sub frame?

I don't like these old timers shakin' their finger at me either.

I am still waiting for someone to identify the reasoning for GM installing
the LCA bushings on seperate centerlines.....

You built a whole cradle? I was thinking about tackling one but haven't decided yet.

Yes, We have found that once you remove most of the squat and take out the considerable amount of slop all the bushings have that the car hooks so much better and is much more consistent off the line.
Only problem with doing the solid bushings is it raises the car up. When you put the solid bushings in and then let it back down on the ground you see how much the car was sagging down with the rubber bushings.
We did a bunch of work to our car to get it to consistently hook hard off the line.
Our coilovers
Solid cradle bushings
Raised inner control arm mount points that allowed us to lower then car down with zero camber.

With this set up we have been able to pull 1.39 60ft times on the motor with no power adder and our first hard hit on nitrous went a 1.35 60ft a couple weeks ago.
All this is done on a 275 drag radial

LOL...We may as well have! But no, we started with a stock cradle and
arms and modified everything necessary to get incremental
adjustment in camber, toe and a couple of other factors.

Please don't everyone get excited, our project is to find answere not
sell product.

A quick question Chris....when locating your new LCA mounting points
on the cradle, did you correct for the bushing centerline offset or
build it into the new mounts?

We just raised the inner mount up as far as we could. The outer mount has a hiem joint so it can swivel up without binding.

I may upgrade from my poly subframe bushes... Are the solid spacers on your website?

Do you solid mount the bushing on the back of the differential as well?

No, but we are using our 9" kit and it has the big single heavy duty BMR bushing.

I went right for the Delrin spherical bushings on the inner and outer, to eliminate any binding.

Looks good!

How do you adjust camber and toe?

The photo doesn't show the other leg....if it has a bushing with a threaded shank, then you should be able to accomplish proper toe.... but camber???

Your description made me feel that both side were constructed in a similar manner.

Toes adjusted by the outer, camber was taken out of the arm itself.

Kinda as I had guessed. The toe adjustment is pretty straight forward
but camber is fixed.
We built camber adjustment into our project.

That looks like a good bit of work that you tackled with good results,i would suggest you pick up the mounting points as much as you dare,it will help you a ton.I wouldnt do solid mounts on a street car,there are reports of camaro cradles ripping and coming apart with people using the solid pfadt mounts,you need a little give.

I don't know which way to go. I might just jig up the rear cradle and do something different. So nothing binds and I have adjustability.

Question

It's not an IRS.... but, curious if this
SRA kit/setup would resolve/eliminate most/all the issues being discussed in this thread?
Might even be more overall cost friendly.

Kind of mind boggling (at least for me) considering the various upgrades/cost for an improved/bullet proof IRS...
such as, but not limited to.... 8.8 or 9" replacement / Various CoilOvers setups / Bushings /
A-Arm notching or replacement / replace the cradle / eliminate Toe Links / etc etc

Additional pics of this SRA Kit....click

Thats one of "proper" ways to go... for sure.

I remeber seeing one of these at the lsx shootout a few years ago,broke second pass.Anyway it will cost $1000s more to do a complete safe SRA setup ,you will degrade ride as well as handeling.

The SRA route is very well developed and proven......but when you play
follow the leader, you will always be second.

If I was going to race my car on the regular, I'd probably go the SRA route. They can be made to drive and ride quite well. Just ask the mustang owners. I know we tend to feel a smug towards them at times, but lets face it, that chassis is outstanding for a 40+ year old design.

I heard about a 9" equipped IRS Camaro with a similar issue, except the cause was a shattered side gear in the LSD. But that couldn't possibly be the case with this SRA car, or could it?

The Moser SRA kit is a nice kit for sure, we sell them if anyone is seriously looking at getting one. We can also install it, there is some fab work required (not a bolt in kit)
There was a thread a few weeks ago where I priced our 9" kit out compared to the Moser kit and it wasnt any cheaper. In fact, our kit was cheaper because it doesn't require a brake kit.

And sure, SRA's and IRS use the same internals so they all are prone to breaking.

It is a great design. Hell, the 05 GT bested the 05 GTO on the skidpad in that infamous Car and Driver article, and they've improved upon the set-up since then.
