I have to put new Lower Control Arms on my 84 Z/28. My question is , what are the pros and cons of each? It's predominately a daily driver car that sees a lot of street racing duty. We don't have a quarter mile track around here so it's street race or nothing. Are the adjustibles worth the extra money?

 

This has been talked about a few times before, and there is a great discussion on this with examples and illustrations of the how and why of adjustable LCAs. I would recommend you read it first, as it might answer your questions.

A small bit of extra to think about....if a part is adjustable, it lets you fine tune the installation. However, it also lets you get it wrong, or maybe WAY WRONG!
