Noise and vibrations are not really worse, maybe just a little.

However heavy acceleration now is completly stable and straight. Compared to before, it really felt like a loose rear axle. lol
I did replace both of the rear cradle bolts (rear) and reused the two front ones because shipping took some time.
Might replace them somewhen in the future, they arrived after I was done...
I carefully removed the old bolts by hand with a ratchet to avoid further stress in the material. When I reused them I carefully just torqued the final pass to just 90°, no more.

Definitely worth it!

Yeah, that's what we were talking about, glad to hear it's working for you, too

My car is much more planted with the lockout kit, which I'm very happy about: when I mat the pedal, it just goes without any wiggle, and it feels more precise in turns.

I didn't notice any increase in NVH, but the car would have to be stock to make a valid comparison, long tube headers and the supercharger both increased the noise floor.

Jumping in here: So, I had the BMR Cradle Lock Kit and Bushings installed... I read above on a post about increased vibration or a little noticeable vibration... Is that a thing, BMR kit causing vibration? Since having mine installed, as arpad_m mentioned, when I mash the pedal it just goes straight. I noticed almost ZERO wiggle, if any at all (what I do feel could be the tires cause a slight sway). But, I do noticed a newer rhythmic vibration from the rear now. I'm still trying to figure out if it's the MT ET Street R's causing the vibration or not. Anyway it's a great kit for the dig and going straight!

Could be the kit or could be the kit exposed something else. I don't remember that in my car, the Camaro. But I had near identical lockout kit in my 15 mustang and on the highway I could def hear the rhythmic whiiiirrrrrr of the gear set.
