Rear Cradle Swap - What Should I Change While It's Out?

I bought a '16 Scat Pack rear cradle to swap into my '06 SRT8 Charger. While I have the cradle out are there some upgrades that would be worthwhile? New rear cradle bushings? Rear sway bar (it currently has a 19mm factory unit)?

You'll need a one piece or custom two piece driveshaft. It's a real improvement and not that hard to do.

If you can find a set of solid bushings, then put those in.

I have them in my car that I drive every day. I don't think I can even feel the difference other than when I launch at the track. I have a 1 pc alum drive shaft as well. I don't feel that, but it does kind of broadcast a clunk I have in my differential. It's a pretty subjective thing. Almost every modification I've made has sacrificed some level of comfort, and I would be lying if I said my car is comfortable, but it feels, sounds, and drives great in my opinion, and that's better than a luxury cruiser. My wife on the other hand wouldn't ride around the block in it.

I have the CTP aluminum bushings. I bought them through BFNY a few years ago.

I would do sways, sub frame bushings and adjustable control arms while the cradle is out.

After looking into the rear sway bar options, I'm not sure there is anything out there that would be much of an upgrade. The Scat Pack rear sway is 19mm, the police sway is 20mm, and the other aftermarket sways are in the same ballpark.

For adjustable control arms, is something like this from BMR recommended or something like this from Spohn?

Just talked to BFNY and they don't have any of the aluminum CTP bushings in stock. He's trying to find another machine shop to fabricate the bushings but so far there is no ETA.

Any other good alternatives to the CTP solids?

Yes, even with a stock bar. Damn things are massive lol. Doesn't hurt that Bwoody is local for me.

Any clearance issues with them being so much bigger than stock?

I don't mean to derail your thread, but what is the advantage of the change you are making? I have a 06 Maggie, is the swap something I should consider?
The ZF diff in '15+ Scat Packs and Hellcats has a 230mm ring gear (vs 226mm in the Getrag and 215mm in the older LX vehicles) and 4 mounting points for the diff in the cradle vs 3 in the earlier cradles. Basically a direct bolt in cradle with a diff that's stronger than the Getrag.
