Lower Control Arms & Sway Bars - Upgrades

I have been looking at Lower control arms and sway bars to try and control some of the body roll and rear end noise in my car. I have FE2 suspension (OEM) and was looking at putting beefier rear and front sway bars in the vehicle. Read on some old forum posts that a fat rear bar will likely crack the original lower control arms so now I am looking at those as well.

UMI seems to be a great place to get LCAs from... I did see that new POLY bushes will make the car ride stiff compared to the OEM rubber ones. Is this the case? I'm looking to keep the ride as squishy as possible, but remove some sway and roll in turns/corners.

Anyone have any experience with the standard UMI bars? What about the Roto joints? Would those make the car ride more smoothly compared to 2 POLY bushings? Links below to see what I am talking about. The Roto joints look really interesting, but can't find much about just a streetable car that's driven gently most of the time.

Also, it's been recommended that I check out BMR sway bars - their rear bar is fat and should really control the back end pretty well. Front bar is smaller, but the set would probably even the car out well (replace both).

Thanks for your thoughtful advice!

Are there any rear braces like this that work with the sway bar?
0. Unlike the front frame and front swaybar, the rear sway bar and the rear frame brace are too far apart from each other to interact with each other.
1. A rear frame brace can be a tow hitch, or anything else that reinforces the connection of the rear frame horns.

2. Again, physically and conceptually separate from a tow hitch or any other sort of rear frame brace, consider:
a. Dick Miller Racing Rear Triangulation Braces
b. making the swaybar act between the frame and the axle instead of against the rear trailing arms
If it turns out that it's easier to order BMR or UMI lower trailing arms, than to order 9C1 lower trailing arms, I get why you might wind up with BMR or UMI lower trailing arms.
Would not be surprised if the UMI's bushings-&-lube arrangement was basically identical.
