Hi aeoman, to the forums

I can't help you directly, but here is a thread describing a very similar problem Ted Jannetty was having, with tons of tips and his solution: https://www.camaro6.com/forums/showthread.php?t=525356

The BMR rear cradle lockout kit is very helpful in terms of added launch stability and body roll control, I have it installed as well, but you shouldn't have much (if any) wiggling and fishtailing on a stock ZL1 with good tires to begin with. If the reason you're looking at suspension upgrades is to fix your rear end stability problem, you're going in the wrong direction, the suspension should be fine for these basic requirements.

My SS has much more than stock ZL1 power, yet it's rock stable under load even with its slightly inferior FE3 suspension and its simple mechanical LSD (although I do have MRC, too). This is the norm for the 6th gen, don't stop troubleshooting until you can mash the skinny pedal and have the car accelerate straight as an arrow.
