Thanks for the info, that was a lot of help.I'd go with the cradle lock out first between those two choices. You want to secure the subframe and remove deflection in the suspension components to remove wheel hop. Next, I'd replace both the toe link bushing and the rear lower control arm bearings. Neither are that expensive, both involve a bit of labor to replace. The below video is for a Cobra IRS setup, but the theory applies to the IRS in our cars - watch first 4 minutes, then fast forward to 12 minute mark.
Also a good s550 specific video
Def go with Steeda! Was one of the first upgrades to RoadCone... The stop the hop kit.Plenty of options here - many of our S.C. Steeda Performance Vehicles run the Stop the Hop Kit (Ultimate Package):

Congrats! Car looks like a beast. I did ONLY steeda rear braces, very cost effective and took an hour to install and it took care of 90% of the hop. For me, no sense in spending way more for a limited extra gain. Absolutely no added NVH.I have a 19 gt and had a vortech si jt installed. I’m making 659 rwhp, I’m planning on getting a fore fuel system in the future so I can hit my goal of 900 rwhp. I know I can get a lot more then 900 but that’s all I really want. I don’t want a track only car. The main issue I’m having right now is wheel hop. It wasn’t bad before the sc but now it’s very noticeable and it’s very annoying. Does anyone know what I need to get to stop it? I don’t want to get a whole suspension kit. Just something to stop the hop.
@TJ - well designed kit, appreciate you all.Congrats! Car looks like a beast. I did ONLY steeda rear braces, very cost effective and took an hour to install and it took care of 90% of the hop. For me, no sense in spending way more for a limited extra gain. Absolutely no added NVH.
