Default suspension help, feels strange under hard throttle

Hi Everyone,

I recently bought a 2005 z51 with a built 408 and full z06 conversion including suspension. The car feel's very strange under hard throttle and high speeds (Ex: WOT 60-120mph). It feels as if I'm riding around on crinkle walls and sways around until you lift off the throttle. I have stock wheels and tires and it was recently aligned. The shocks feel fine and the car feels fine just cursing at 120mph so I'm stumped on what the problem could be. Any ideas or help is appreciated!

What is a full "Zo6" conversions? Aluminum frame, dry sump, etc? or fenders and sway bars?

Fenders, wheels, sway bars, brakes, shocks and rear diff.

Did it feel this way before the alignment? You could have loose control arms in the rear, a loose wheel bearing maybe a loose tie rod. Maybe a loose front or rear cradle.

Sway bar end links? I have the same problem up around 140. I just bought a set of new sways and pfadt coilovers. My end links ended up being shot.

I put it on the lift today and no bolts are loose. The only thing I could find was one of the four bolts for the rear cradle is broken off. It looks like it is a mount but I can't find the replacement part or part number anywhere online.


I'm looking for the two black mounts in the picture. Anyone know a part number or where I can find it?
