To start off, car has 122k on it and is a true dd. It has Koni 4/4s, strano springs, watts link, strano sway bars, and LCA relocation brackets.

Should i replace the bushings in my control arms with poly bushings? Advantages? Disadvantages? differences?

Should I just invest in UMI LCAs with the roto-joints? Ride difference? Handling Difference? Noise? Pros and cons?

Appreciate any insights.

Hello,

Based on your set up it looks like you are going more for handling than anything? If so I would recommend the Roto-Joints on at least one end for you. The Roto-Joints do not bind like poly bushings, they are virtually noise free while still maintaining a comfortable ride. Here is a set too look at I would recommend- Roto-Joint/Poly combination

Please let me know if I can help anymore. Thanks!

For a great handling street car the UMI poly/roto-joint is the way to go, if you do some competion the double roto-joint would be a good, but for a DD I'd go poly/roto & would complement that great set up you have

hmm, I think I'll be going with the rotojoint/poly set up. What kind of difference will there be between that and stock?

The poly end will bolt to the unibody and filter noise but has less flex than the stock rubber bushings, the roto-joint end will let the suspension move more freely and less binding under hard cornering than a poly/poly set up + the roto-joint is adj. & are able to rebuild.
