Front Radius Arm Inserts

With the rear LCA you may need adjustability if you lower the car to reach a certain camber spec, but I don't believe the radius rod is affected by lowering (could be wrong though ); also, like the radius rod hole you can also elongate the subframe bolt hole for the rear LCA and possibly not need an adjustable arm.

Adding caster makes a significant difference in the way the 5th Gen drives. Adding SAI is like caster on steroids.

looks like a must do for my staggered set up

A spherical is the best choice for a race car. Short of that, JPSS Aluminum Billet Inserts are 'hard' to beat, with more control surface area than even the nylon Z/28 in GM speak snubber.

I am new to suspensions and in the process of starting to replace OEM parts for the next couple of months. I have a 2ss 13'. I have seen after market components for the rear but nothing on the OEM front radius and lower control arms. Are the Z28, ZL1 and SS front radius and lower arms different?

Like these we make for the radius arms? The control arms wouldnt gain anything from changing that bushing.

Yes they are. Mostly in the size of the void in the rubber bushing. The factory inserts are also different in size and hardness.
Smaller voids and harder rubber translates to less deflection = better steering control/inputs. Side effect is harsher ride and increased road noise.

Uh, ive got both types of radius srms, Z28 and SS, the rubber bushing portion is exactly the same. Onky the insert is different. The arms in my picture I posted are Z28 arms I bought to verify, then I installed our spherical joints.

Where can i get these joints??

I have 30 sets at the shop, I am having the adjustment wrench made to complete the sets. Pegasuscnc.com is where they will be sold along with our current parts and the others I have just finished testing such as our aluminum trailing arms and toe rods.

The joints have been done for over a year actually, lol, but I deployed sooner that I was supposed to so I didnt get the wrenches produced, they have been on my car for a year and a half, still as tight as the day I put them in.

[2012LS3VERT]

If y'all were at CamaroFest I actually have them in my trunk.

reserve a set for me pls

No problem. I have plenty of sets, just no wrenches until a week or so from now. I just brought one arm with our joint in to Camarofest. We will likely offer either an install service or offer them already installed in new arms also.
