I want to get the two lower Adjustable Control arms. I have seen three different one: Hsport, Alta and Ireland Engineering. Hsport uses a urethane w/ Aluminum Turn buckle w/ zerk fittings. Alta uses heim end that has Teflon w/ all steel contruction. Ireland engineering has two version: Street w/ urethane and aluminum turn buckle and Race w/ heim ends. The Alta is the most expensive at $299, the hsport at around $215 and Ireland is $190.

There was some post on the Hsport but none on the other brands. Is urathane better for the street cars? Negative effect on using heim end for the streets? Any other brands out there? Are they all the same?

 

I have RDR control arms: aluminum with heim joint ends. I actually replaced the ends with stronger better heim joints by Aurora. The setup is great for the smooth roads and track, and a bit brutal on all others. Urethane is more forgiving (better) for the street.


Here is RDR's site:

Here is a site where you can purchase better quality rod ends:

Thanks MGCMAN. Thanks for letting me know that heim joints are not suitable for the street. Looks like the Hsport wins because it has zerk fittings and no one else has them.
