Yeah after looking at the pics it kinda does have rust on 80% of it. But is it from the poly do you think?

How long ago did you install those bushings? It’s not likely that poly bushings of themselves would produce a fracture like that. If torque settings were too high, or bushing lubrication was lacking (poly bushings do require periodic, appropriate lubricants), those might have contributed to the apparently long-developing (metal fatigue?) fracture.

Poly Bushing ARE harder on a car, but I agree, its been cracked a while. Welcome to high performance parts :)...Replace it and see what happens. We have NOT broken one of those yet on the race car, So that bodes well for you .

Need more pictures. In the one posted, it looks a bit squished in front... maybe...
Unlikely that poly bushing would alone be the root cause. Need more information though. The "toe link" takes the fore-aft loading in the suspension, so the location looks close to the area of high bending stress.

Doms' rear lca's are about $380 not to mention they have height adjust for the spring and you can move the wheel out up to 1.5" I think but you have to have either his toe or camber arms to adjust out.

I say it was cracked a long time and finally let go. That clean metal was the only thing holding it. I actually got massive camber/toe arms. If that failed check ur rear lca where the sway connects for cracks. Thank godness I live in socal and no rust

I reinforced my rear lca at the sway bar hole but it snapped at the outter bushing yesterday

Look's like you could use some toe-link's from Dom or CFM, & add the CFM boot's too. Dom has rear lower control arm's for you too= awesome! Or you could just get some new one's & run them w/ the stock bushing's. I've run a Steeda rear bar w/ no problem's for a few year's now.
