I was talking to a guy i know, he had just bought a 1992 camaro with aftermarket trailing arms. when i looked close i noticed they did not have bushings just a hole drilled in them with a thick bolt.

my question is why are they like that, is it a racing thing? what are some pros/cons of these type of trailing arms?

 

Their should also be a sleeve that the bolt goes through. That set up would be ok for a racing application! But when it comes to the street I would highly suggest going with a poly bushing. Going with the certain set up would still give you the comforts of a good ride quality. But if you are looking for a racing set up I would suggest going with at least a single adjustable or even a double adjustable to allow you to be able to fine tune the rear end. Below is a link to show you what all UMI Performance has to offer!

alright thanks just i have never seen that done before. now that i noticed it i see it more and more offten.

 

good advice, but dont use poly on the rear control arms.
use either rubber or rod ends or jimmy joints, johnny joints... whatever they are called.
UMI is good
also consider:
SPOHN
HOTPART
BMR

any of these guys are better than stock and running a bolt through the arm.

 

Hello, we offer several different styles of lca's. They are available with urethane bushings, rubber bushings or QA1 rod ends. They all have a different purpose and are available in adjustable or non adjustable versions. Give me a call here at the office and i can explain what the benefits of each type are.
